Can you mount a smoke detector vertically?

Tray Shaped Ceilings: Smoke alarms or smoke detectors shall be installed on the highest portion of the ceiling or on the sloped portion of the ceiling within 12 in. (305mm) vertically down from the highest point.

Do smoke detectors need to be on the ceiling?

Smoke alarms should be installed at least 10 feet (3 meters) from a cooking appliance to minimize false alarms when cooking. Mount smoke alarms high on walls or ceilings (remember, smoke rises). Wall-mounted alarms should be installed not more than 12 inches away from the ceiling (to the top of the alarm).

Placement of Smoke Detectors – Best Smoke Alarms

Properly installing your smoke alarms – and making sure they work – is an important step in protecting your home and family from fire.

It is important to have enough smoke detectors in the house. Fire research has shown that fires can spread much more quickly with today’s modern facility than they used to when more natural materials were used. For this reason, it is important to have a sufficient number of properly placed smoke alarms to maximize the escape time available. For many years, NFPA 72, the National Fire Alarm and Signaling Code, has required, as a minimum, the installation of smoke alarms in every bedroom (even in existing homes) in addition to the requirements outside of each sleeping area and on every level of the home. (Additional smoke detectors are required for larger homes.) Homes built to earlier standards often fail to meet these minimum requirements. Homeowners and law enforcement agencies should recognize that detection requirements have changed over the years and take proactive steps to ensure each home has an adequate number of smoke alarms.

Install smoke detectors

Choose smoke alarms that carry the label of a recognized testing laboratory.

Install smoke alarms in every bedroom, outside of every sleeping area, and on every floor of the house, including the basement.

On non-bedroom levels, install alarms in the living room (or study or family room) or near the stairs to the upper level, or both.

Smoke detectors installed in the basement should be installed on the ceiling at the base of the stairs leading to the next level.

Smoke alarms should be installed at least 3 meters away from any cooking appliance to minimize false alarms when cooking.

Mount smoke alarms high on walls or ceilings (remember, smoke rises). Wall mount detectors should be installed no more than 12 inches from the ceiling (to the top of the detector).

If you have sloping ceilings, install the alarm within 3 feet of the top, but not within the top of the top (four inches below the top).

Figure A.29.8.3.1 from NFPA 72, National Fire Alarm and Signaling Code (2013 Edition).

Figure A.29.8.3.1 from NFPA 72, National Fire Alarm and Signaling Code (2013 Edition). Do not install smoke alarms near windows, doors, or ducts where drafts could affect their operation.

Never paint smoke detectors. Paint, stickers or other decorations may affect the alarm function.

For the best protection, wire all smoke alarms together. When one smoke alarm sounds, all of them sound. The connection can be via hardwired or wireless technology.

When installing networked smoke alarms, it is important that all smoke alarms are from the same manufacturer. If the alarms are not compatible, they may not sound.

There are two types of smoke detectors – ionization and photoelectric. An ionization smoke detector generally responds better to flaming fires, and a photoelectric smoke detector generally responds better to smoldering fires. For the best protection, both types of alarms or combined ionization and photoelectric alarms, also known as dual sensor smoke detectors, are recommended.

Retain the manufacturer’s instructions for future reference.

Testing of smoke detectors

Smoke alarms should be serviced according to the manufacturer’s instructions.

Test smoke detectors with the test button at least once a month.

Make sure everyone in the house understands the sound of the smoke alarm and how to respond.

Follow the manufacturer’s instructions for cleaning to keep the smoke detectors working well. The instructions are included in the package or can be found on the Internet.

Smoke alarms with non-replaceable 10-year batteries are designed to remain effective for up to 10 years. If the smoke alarm beeps and warns you that the battery is low, replace the entire smoke alarm immediately.

Smoke alarms with any other type of battery will need a new battery at least once a year. When this alarm beeps and warns that the battery is low, replace the battery immediately.

When replacing a battery, follow the manufacturer’s battery list on the back of the alarm or the manufacturer’s instructions. The manufacturer’s instructions are specific to the batteries (make and model) that must be used. The smoke alarm may not work properly if a different type of battery is used.

Networked smoke alarm devices increase security

In a Consumer Product Safety Commission (CPSC) survey of homes with fires, including fires where firefighters were not called, connected smoke alarms were more likely to go off and warn residents of a fire.1 People may be aware of a fire hear without a smoke detector.

When smoke alarms (connected or not) were present on all floors, they sounded on 37% of fires and alerted occupants on 15%.

When smoke detectors were not present on all floors, they only triggered 4% of the fires and alerted the occupants in only 2%.

In homes with interconnected smoke alarms, alarms went off on half (53%) of the fires and alerted people on a quarter (26%) of the fires.

Where should smoke detectors be placed in living room?

Smoke rises, so mounting smoke detectors high — usually on ceilings — is the best option. If you choose to mount a smoke alarm on a wall, placing it less than 12 inches from the ceiling would be best. Find a spot away from air ducts, windows or anywhere with a draft that could keep smoke from reaching the detector.

Placement of Smoke Detectors – Best Smoke Alarms

We often don’t think about house fires or other disasters until they strike. But preparation is vital. In most regions, residential smoke detectors are a legal requirement – and they can significantly improve outcomes in the event of a fire. The question is, where is the best place to mount smoke alarms to protect your property and loved ones in an emergency?

How does a smoke detector work?

Before we delve into fire alarm placement, it’s helpful to understand how smoke alarms work to reduce the risk of devastating fire damage and injury. There are three types of smoke detectors: photoelectric, ionization and dual smoke detectors.

A photoelectric detector measures light as it hits the sensor. These types of detectors are best at detecting smoke fires. An ionization detector detects when smoke enters the ionization chamber and the ionized smoke particles are neutralized. The drop in electrical current activates the alarm. Ionization detectors respond better to flaming fires. A dual sensor smoke alarm is a combination of both.

Where should smoke detectors be placed?

According to the NFPA, the best place for smoke alarms is inside and outside of the bedrooms and on every level of your home, including the basement. Depending on the size of your home, you may need multiple smoke alarms. Smoke alarms with two sensors throughout your interior would be most effective in detecting both types of early fires.

Smoke rises, so mounting smoke alarms high up – typically on the ceiling – is the best option. If you choose to mount a smoke alarm on a wall, it is best to place it less than 12 inches from the ceiling. Find a spot away from air ducts, windows, or anywhere with drafts that might prevent smoke from reaching the detector. Linking all smoke alarms together also gives you broader protection – if one alarm goes off, they all do.

Where to place smoke detectors in the kitchen

People generally avoid placing a smoke alarm in the kitchen for fear of setting it off while cooking. But a smoke alarm is important in any kitchen simply because that’s where fires often start—even if you’re not around when they do. To minimize false alarms, detectors should be mounted at least 10 feet from the stove or oven. In a small kitchen, this can be difficult. Your only option is to place the smoke alarm just outside the kitchen area 10 feet or more from the stove.

sleeping areas

Smoke alarms should be placed inside the bedroom and just outside the bedroom areas e.g. B. in a hallway. If you don’t have enough smoke alarms to put everywhere, place one outside of bedrooms in a spot where anyone sleeping can hear the alarm. As already mentioned, networking of wireless or wired smoke alarms helps to solve the hearing problem. For example, if the smoke alarm in the basement of a two-story home goes off in the middle of the night, networked smoke alarms will sound throughout the home, quickly alerting anyone sleeping upstairs.

basement, cellar

Don’t forget to install a smoke detector in the basement. Networking is ideal for alerting you when there is smoke in the basement. Otherwise, you may not hear the alarm until the fire spreads to other areas.

How to install a smoke detector

Battery powered smoke alarms are among the easiest home security devices to install. They usually come ready to use – all you have to do is assemble them. You can follow the manufacturer’s instructions to install your specific smoke alarm, but in general the steps are consistent.

Unpack the detector and read the documentation. Insert the battery or pull the protective tab off the battery to activate the alarm. Choose a draft-free place on the ceiling or on a wall that is 30 cm from the ceiling. Attach the mounting bracket. Connect the smoke detector. Test the smoke detector by pressing the “Test” button. It should produce a loud noise that is easily audible in the general environment.

Wired smoke alarms may require an electrician who is able to make the connections and wire them together.

Smoke detector maintenance

Smoke alarms don’t require much maintenance other than regular battery or electrical connection checks. Make it a habit to test your alarms once a month by pressing the test button to make sure the smoke alarm sounds. If you hear a chirp, the detector’s battery is probably low and should be replaced. Even if your alarm doesn’t beep, replace the batteries in all your smoke alarms once a year.

sleeping place

Do smoke detectors need to be replaced?

If you properly maintain your smoke alarm by replacing the battery annually, you usually don’t need to replace the entire device. However, some smoke alarms come with a built-in, non-replaceable battery. They usually last 10 years. When the alarm beeps on this type of model, the battery is low and it’s time to replace the smoke detector.

What to do if your smoke alarm goes off?

Understanding fire safety can mean the difference between life and death. It is important that everyone in the family recognizes what the smoke alarm sound means and what to do. A fire alarm should always be taken seriously, even after multiple false alarms. Even young children can be taught what to do when a fire alarm goes off.

A home security plan can be vital so everyone at home knows what to do in the event of an emergency. It is important to have an escape plan in the event of a fire, including where everyone should meet outside of the home.

Smoke detectors give false alarms. If you hear a smoke alarm, find the source of the smoke before calling 911. A small grease fire in a pan, for example, can be easily extinguished. However, if there is heavy smoke or a fire that you cannot control, evacuate the home immediately and call 911.

How many smoke alarms do I need in my home?

When it comes to protecting your family, the first step is to be prepared. Smoke alarms are your first line of defense against a home fire, giving your family early warning and time to escape safely. At First Alert, we provide reliable protection you can count on to help protect what matters most. Do you know how many smoke alarms your home needs to fully protect and what type is best for your needs? Here’s what you should know:

According to the National Fire Protection Association (NFPA), smoke alarms should be installed on all levels of your home, including the basement. Fire alarms should also be installed inside each bedroom and outside each sleeping area. For example, a two-story, three-bedroom house should have at least seven smoke detectors. Homes that have a set number of hardwired alarms can still place additional battery powered smoke alarms throughout the home. There aren’t too many smoke detectors in the house! Just make sure the fire alarms are properly placed in each area.

Where do I install smoke detectors?

For smoke alarms to function optimally in your home, they must be properly installed in each room. In the kitchen, smoke detectors should be installed at least 10 feet away from cooking appliances to minimize the number of false alarms. Smoke rises, so smoke alarms should be mounted high on walls or ceilings. When installing a battery powered smoke alarm on a wall, the top of the smoke alarm should be no more than 12 inches from the ceiling. Remember that fire alarms should not be placed too close to vents, ceiling fans, or windows for them to work properly. Also remember to test your alarms monthly to ensure they are working properly and replace the detector batteries every 6 months.

What type of smoke alarm should I have?

There are many different types of smoke alarms such as battery powered smoke alarms, hardwired smoke alarms, networked smoke alarms, smoke and carbon monoxide combo alarms and more!

Requirements for Smoke Detectors and Door Releases for Smoke Barriers BY WAYNE D. MOORE

Doors used to protect openings in smoke barriers provide an integral safety feature in any healthcare environment. The 2016 edition of NFPA 72®, National Fire Alarm and Signaling Code, provides the requirements for installing smoke detectors for door entry service. Activation of smoke detectors will release the doors and help them close if smoke enters the area near the door.

If the door is only released by the smoke detector via internal relay contacts, a state-approved test center must have tested and listed the detector for release mode.

The number of smoke detectors required and all clearance requirements listed in Sections 17.7.5.6.2 to 17.7.5.6.6 apply when the detectors are used for the sole purpose of door release from smoke barriers. If the doors must be closed in response to smoke flowing in either direction in the corridor space, the code includes specific requirements for detector location. The code also includes graphics of the required positions that meet the requirements based on the depth of the wall section above the door and the number of doors in the doorway. For example, if the depth of the wall section above the door is 24 inches or less, the code only requires a ceiling-mounted smoke alarm on one side of the doorway. If the designer dictates the use of wall mounted detectors, then the code requires two detectors, one on each side of the doorway.

If the depth of the wall section above the door is greater than 24 inches on only one side, then the code only requires a ceiling-mounted smoke alarm on the higher side of the doorway. However, if the depth of the wall section above the door exceeds 24 inches on either side of the passage, the code requires two ceiling or wall-mounted detectors, one on each side of the passage. If the depth of the wall section above the door exceeds 59 inches, the code requires an engineering assessment to be conducted to determine the need for additional detectors. Finally, if the design dictates the use of a listed door frame mounted smoke alarm or a listed integrated alarm and door closer combination, the code only requires such an alarm when installed in accordance with the manufacturer’s published instructions.

The locations for ceiling mounted smoke alarms installed on a smooth ceiling for a single or double door must coincide with the center line of the door, no more than 5 feet from the door and no closer than 12 inches to the door. Regardless of the depth of the wall section above the door, if the electric strike is intended to prevent smoke transmission from one room to another in one direction only, detectors located in the room containing the smoke must meet the same requirements as for above the doors leading from this room. If a room includes multiple doors, the code requires additional ceiling-mounted smoke detectors, depending on the number of doors and the distance between them.

Given all of this, it’s easy to see why detector spacing can prove a bit intimidating for the specific purpose of controlling smoke spread in corridors or smoke compartments. But smoke alarms that are part of a code compliant open area detection system covering the room, corridor or enclosed space can meet all of these requirements for smoke barrier door opener service. In other words, when smoke detectors protect a corridor or other enclosed space using the Code’s open space distances, none of the requirements in sections 17.7.5.6.2 through 17.7.5.6.6 apply.

How close can a smoke detector be to a wall?

For wall mounting (if allowed by building codes), the top edge of Smoke Alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.

Which places to avoid for smoke alarms? LOCATIONS TO AVOID FOR SMOKE DETECTORS For best performance, AVOID installing smoke detectors in these areas: Where combustion particulates are generated. Combustion particles are formed when something is on fire. Areas to avoid are poorly ventilated kitchens, garages and boiler rooms. If possible, keep the devices at least 6 meters away from the sources of the combustion particles (stove, oven, water heater, space heater). In areas where 6 meters (20 feet) distance is not possible – for example, in modular, mobile, or smaller homes – it is recommended that the smoke alarm be located as far away as possible from these fuel-burning sources. The placement recommendations are intended to keep these alarms a reasonable distance from a fuel-burning source, thereby reducing “unwanted” alarms. Unwanted alarms can occur when a smoke alarm is placed in close proximity to a fuel burning source. Ventilate these areas as much as possible.

In air currents near kitchens. Air currents can draw cooking smoke into the sensor chamber of a smoke detector near the kitchen.

In very humid, humid or misty areas or directly near bathrooms with showers. Keep the devices at least 3 meters away from showers, saunas, dishwashers, etc.

Where temperatures are regularly below 4°C (40°F) or above 38°C (100°F), including unheated buildings, outdoor spaces, porches, or unfinished attics or basements.

In very dusty, dirty or greasy areas. Do not install a smoke alarm directly above the stove or stove. Clean a laundry room unit frequently to keep it free of dust or lint.

Near fresh air vents, ceiling fans, or in areas with high drafts. Drafts can blow smoke away from the device and prevent it from reaching the sensor chamber.

In insect infested areas. Insects can clog openings to the sensor chamber and trigger unwanted alarms.

Less than 305 mm (12 in) from fluorescent lighting. Electrical “noise” can interfere with the sensor.

In “dead air” spaces. “Dead air” spaces can prevent smoke from reaching the smoke detector. AVOIDING DEAD SPACE “Dead air” spaces can prevent smoke from reaching the smoke detector. To avoid dead air spaces, follow the installation recommendations below. On ceilings, install smoke detectors as close to the center of the ceiling as possible. If this is not possible, mount the smoke alarm at least 4 inches (102 mm) from the wall or corner. For wall mounting (where building codes permit), the top of the smoke alarm should be placed between 4″ (102mm) and 12″ (305mm) from the wall/ceiling line, below typical “dead air” spaces. Install the first smoke alarm on a peaked, gabled, or cathedral ceiling within 0.9 meters (3 feet) of the top of the ceiling, measured horizontally. Depending on the length, angle, etc. of the ceiling slope, additional smoke detectors may be required. See NFPA 72, A.11.8.3 for details on requirements for sloped or peaked ceilings.

Where should smoke detectors be placed in living room?

Flat Ceiling

As hot smoke initially rises and then spreads out, smoke alarms should be located on the ceiling. This is so that smoke can reach the detector’s sensor chamber as early as possible. If it is not possible to install the smoke detector on the ceiling, the unit can be installed up to 575mm below it.

Placement of Smoke Detectors – Best Smoke Alarms

Positioning of smoke and heat detectors

The positioning of your smoke and heat alarms is important to ensure effective detection in the event of a fire. Each smoke and heat alarm includes positioning instructions in the supplied instruction manual; However, below are some helpful tips and a basic guide to positioning detectors in the home. Please Note: It is your responsibility to ensure detector sites comply with all applicable building codes.

flat ceiling

Smoke alarms should ideally be installed in the middle of the ceiling. It is recommended to position the detector at least 300 mm away from walls and lighting/decorative objects (see fig. 1.). This is because air cannot circulate effectively in corners, and objects such as light fixtures can block smoke and heat from entering the sensor chamber.

Since hot smoke first rises and then spreads, smoke detectors should be mounted on the ceiling. So that the smoke can get into the sensor chamber of the detector as early as possible. If the smoke detector cannot be mounted on the ceiling, the device can be mounted up to 575 mm below it. A heat detector should also be located directly on the ceiling; However, if this is not possible, the device can be installed up to 125 mm below.

Sloping ceiling

With a sloping ceiling, the position of a smoke or heat detector must be measured perpendicularly from the top. Smoke detectors can be installed within 600mm and heat detectors can be installed within 150mm of the top (see Fig. 2.). Again, it is important to position the detector as centrally as possible on the ceiling.

How do you stick fire alarm to ceiling?

Putting up a smoke alarm without drilling is super easy. All you need is a pack of VELCRO® Brand Heavy Duty Stick On Coins. Stick one side of the hook and loop coin to the ceiling, and the other half to your smoke alarm. Then simply stick it on!

Placement of Smoke Detectors – Best Smoke Alarms

It goes without saying that every household should have a smoke detector. You never know when you might need it and it could save your life.

So for anyone who’s been putting off installing a fire alarm or is feeling discouraged at the thought of drilling into the ceiling to install one, we’re here to tell you there’s a much quicker and easier way, this to do.

All you need is five minutes and a pack of VELCRO® Brand Heavy Duty Stick On Coins. Read on for our easy fire alarm installation guide.

How to set up a fire alarm without drilling

Installing a smoke alarm without drilling is super easy. All you need is a pack of heavy-duty VELCRO® Brand sticky coins.

Tape one side of the hook and loop coin to the ceiling and the other half to your smoke detector. Then just stick it on!

Installation takes less than five minutes and if you need to remove your smoke alarm to change the battery, simply unplug it.

How much you need?

This depends on your individual circumstances (i.e. the size and layout of your house). But when in doubt, remember that fires can start anywhere. The more fire alarms there are, the higher the level of protection.

What to do with them?

For minimum protection, you need at least one smoke detector on each level of your home. But a smoke alarm in every room (except the bathroom) offers the greatest protection.

Don’t put one in the bathroom as steam can accidentally set it off. And you should put a heat alarm in the kitchen and a fire alarm just outside the door to avoid frequent false alarms.

Test your smoke alarm and change the battery

Smoke alarms require very little maintenance, but according to the fire service there are a few things you should do every year to make sure they’re working properly:

Test it and vacuum to remove dust from the sensors

Change the battery (unless it is a 10 year battery)

And after ten years it is advisable to buy a completely new alarm.

So now you know how to install a smoke alarm without drilling. So make sure you have one installed in your home. And if you know an elderly person who may be struggling to install a fire alarm themselves, stop by and help them install one.

Placement for Alarms

What is the best placement for alarms?

October 7, 2019

smoke detector

Smoke alarms should be mounted in or near sleeping and living areas, either on the ceiling or on the wall. Ceiling mounting is generally preferred as this allows the smoke detector to be placed more centrally in the room. If wall mounting is used, it is best to use an interior wall to avoid thermal air currents that can occur along hot or cold walls. Our units have been tested and work between 40 degrees and 100 degrees Fahrenheit.

Carbon monoxide and combination detectors

Carbon monoxide (CO) and combination detectors should be mounted in or near sleeping and living areas on a wall mounted six inches from the ceiling and six inches from the floor. When installing on the ceiling, make sure that the distance to the wall is at least 15 cm. Since carbon monoxide has almost the same density as air, it is distributed evenly in the room air. Our units have been tested and work between 40 degrees and 100 degrees Fahrenheit.

If your home has a hot water heater or boiler, it is recommended to place a CO alarm in the boiler room and also in the space above or next to the boiler room for the quickest response.

We recommend installing a carbon monoxide or combination detector on each level of an apartment building. You can use the number and location of smoke alarms installed in your home as a guide to the location of your carbon monoxide or combination alarm, in accordance with current building codes.

If the house only has one carbon monoxide or combination detector, it should be installed in the master bedroom or in the hallway outside the sleeping area.

Consider the following guidelines for placement of a single carbon monoxide or combination detector:

Place the alarm at least 5 to 15 feet away from fuel burning appliances.

Make sure the device is not covered or obstructed.

Do not place the device in a dead air space or near a window or door.

CAUTION: Carbon Monoxide alarms only indicate the presence of carbon monoxide at the sensor. Carbon monoxide can be present in other areas of your home.

heat alerts

Heat detectors should be either ceiling or wall mounted. We recommend that you install a heat detector in areas where temperatures can be extreme; like in the attic or in the garage.

NOTE: 135 degree heat detectors are generally not suitable for attic use as most unfinished attics will exceed the detector’s operating temperature. Heat detector model number HD200F would be suitable for this use with an SM120X relay module for smoke and a CO120X relay for carbon monoxide.

Place all alarms

We recommend that you refer to your current building codes as a guide to the location of your detectors.

IMPORTANT: Improper location can affect an alarm’s sensitive electronic components.

NOTE: For more information on your specific alarm, refer to your user manual.

11 Places NOT to Put Smoke Alarms

Having smoke alarms in the wrong location can result in them NOT going off in a fire or nuisance going off. Knowing where these places are could save your life.

bathroom

Smoke alarms should not be installed in a bathroom as the steam from a hot shower or bath often sets off the alarm. The moisture can also damage the alarm over time and cause it to fail. Therefore, do not place a smoke alarm in a bathroom or too close to a bathroom. Any smoke alarm within 20 feet of a bathroom should be of the photoelectric type.

near fans

Place a smoke detector no closer than 3 feet in a horizontal path from the tip of the blade of a ceiling (paddle) fan. The fan tends to blow smoke away from a smoke alarm if placed too close to the fan.

Near air vents, utility grills and registers

Locate smoke alarms no closer than 3 feet from stoves or A/C supply and return grills or registers. Do not place in areas of turbulent air where airflow could prevent smoke from reaching the detectors. Otherwise, you should not place smoke alarms where the air blowing out of the vents can blow smoke away from the smoke alarms.

Windows and sliding glass doors

Avoid installing a smoke alarm near openable windows where drafts can occur. Drafts from a window can actually blow smoke away from the detector.

Within 4 inches of wall/ceiling corners

Dead air space in corner areas. Smoke may not reach these areas until it is too late. Therefore, do not place the smoke detectors in narrow corners.

Near cooking appliances

Do not place near cooking appliances, stoves and ovens. Smoke alarms should be installed at least 10 feet from a cooking appliance to minimize false alarms while cooking.

In oven and hot water cabinets

Do not install smoke detectors in cabinets with gas-fired stoves and gas-fired water heaters. This helps to reduce false trips. Instead, use heat detectors in these locations.

Near washing machines or dishwashers

Avoid placing smoke alarms near dishwashers or washing machines. Alarms should be installed at least 3 feet away from these devices.

garages

Don’t place smoke detectors in a garage, instead use a heat detector. It is recommended to install smoke detectors in rooms that share doors, walls or floors with the garage.

Note that garages are not typically heated or cooled. Actual temperatures in a garage may be above or below the temperature range for which the alarm is designed. Smoke from car exhaust can also cause false alarms or damage smoke detector sensors.

Unfinished attic

Smoke alarms are not designed to work in extreme heat or cold, or in areas where smoke and dust are common, as they could damage the smoke alarm’s sensors. Heat detectors should be used in attics.

Near fluorescent lights

Do not place smoke alarms closer than 30 cm from fluorescent lighting as electrical “noise” and flickering can affect the smoke alarm’s operation.

What is the area covered by a smoke detector?

Approximately 900 square feet is the maximum coverage for a smoke alarm. Beams, ceiling pockets, architectural design, and a number of other factors determine the area that a smoke alarm actually covers.

Heat alerts – what are they? where do you go?

Heat alarms are typically used in locations where smoke alarms may be triggered unnecessarily or falsely. They recognize high heat from fires. Heat alarms can be placed in: kitchens, gas oven cabinets, gas water heater cabinets and in garages as heat alarms do not respond to smoke and are not prone to false alarms from cooking and exhaust fumes. They are inexpensive and are usually available from Home Depot, Lowe’s, and other hardware stores.

Remember

10 Year Battery: All replacement smoke alarms should have a 10 year battery.

Manufacturer Instructions – Read and follow the instructions when installing a smoke alarm.

Test all your smoke alarms regularly; according to manufacturer information.

Replace old smoke alarms (if more than 8-10 years old), replace any damaged smoke alarms and those that have been painted over.

If smoke alarms are linked together and you are replacing one, check that it is compatible with the other smoke alarms. Sometimes smoke alarms from other manufacturers or older models will not work properly with a new smoke alarm; it may fail or some don’t sound.

The time to escape a house fire today is MUCH SHORTER

30 years ago, the average time to escape a house fire was about 17 minutes.

Now it’s about 4 or 5 minutes.

More homes have smoke alarms and carbon monoxide alarms than ever before, and yet escape times have fallen dramatically. The smoke in house fires now contains more toxic gases and the fires burn much hotter.

Inhaling the smoke from house fires today can quickly damage your lungs and cause you to pass out.

Families really need to understand what has happened over the past 30 years to make the fires more dangerous and what they need to do.

The final result

Because of the risk of serious injury, you would not put your seat belt around your neck or install an infant carrier backwards. The same applies if you install a smoke alarm in the wrong place. It’s also important to remember that these codes may vary slightly from one building law to another.

Be sure. Check your own smoke alarms and advise your friends, clients and neighbors.

Due to the amount of flammable liquids typically present in garages and workshops, a higher rated fire extinguisher is recommended. This fire extinguisher fights garage and workshop fires such as paint, wood, gasoline and live electrical equipment.

In a typical house fire, residents have only a few minutes to escape. And since smoke in one area may not reach a smoke detector in another, the National Fire Protection Association (NFPA) recommends installing at least one smoke detector on every level of the home (including the basement), in every bedroom, and outside of every sleeping area. The NFPA also recommends interconnecting alarms to provide better whole-home protection than standalone alarms. Leading authorities recommend installing both ionization and photoelectric smoke detectors to ensure maximum detection of the different types of fires that can occur in the home. Alarms with ionization detection can detect invisible fire particles (associated with rapidly flaring fires) earlier than photoelectric alarms. Photoelectric detection alarms can detect visible fire particles (associated with slowly smoldering fires) earlier than ionization alarms.

Now it’s easier than ever to find out about a possible emergency at home – no matter where you are. Now it’s easier than ever to monitor your home when you’re away with the RemoteLync Monitor and RemoteLync Camera.

Kidde smoke alarms are rigorously tested and approved for use in any room in the home as specified in the instruction manual. Some alarms have additional features that can make them more beneficial to specific areas. For example, a model with super bright LEDs can help illuminate an escape route in a hallway, or a model with a voice alert in a bedroom can reduce confusion by providing specific voice messages about the hazard. Near the kitchen, a model with an intelligent algorithm can help reduce false alarms.

Combined smoke/CO detector

A combination smoke/CO alarm makes it easy to provide both types of protection throughout the home. Industry experts recommend installing a CO alarm on every level of the home – ideally on every level with fuel-burning appliances and outside of sleeping areas. Therefore, a combination detector can meet one of your smoke alarm location requirements as well as a carbon monoxide location.

The Kidde Intelligent Alarm combines the detection capabilities of an ionization smoke sensor with those of an electrochemical sensor used to detect CO. Because carbon monoxide is present in all fires, the collaboration of both detection chambers in an alarm is a breakthrough in the fire protection industry. When one of the sensors detects a potential hazard, it communicates with the other. Depending on what is detected, the alarm will adjust its smoke sensitivity to better distinguish between a real threat and a false one. This constant communication improves the overall performance of the alarm on all fires and greatly reduces the potential for false alarms.

heat alerts

Heat detectors are not suitable for fire detection and must be used as part of a smoke detection system. In some areas of the home, it may be beneficial to use a heat detector that detects fires based on air temperature, rather than a smoke detector that detects particles in the air. Installing heat alarms in attics, boiler rooms, or garages is recommended because these locations occasionally have conditions that can cause smoke alarms to operate improperly. Heat detectors are designed to sound an alarm when the alarm reads a specific temperature. They do not respond to smoke and should not be used as a replacement for smoke alarms, but rather as a complement to a complete smoke detection system.

Placement of fire extinguishers

Kidde has developed some fire extinguishers with features specifically designed for this type of hazard. For example, Kidde’s kitchen fire extinguisher has a proprietary nozzle design that allows for a broad, dispersed discharge of the agent that provides a high volume, low velocity discharge of dry chemical. This is the only UL Recognized Fire Extinguisher for household cooking appliances. The National Fire Protection Association (NFPA) provides minimum recommendations for the home:

Step 1: Choose Primary Fire Extinguishers (Must Have)

To protect your main home, install a 2-A:10-B-C rated fire extinguisher on each level of your home – no more than 40 feet apart. This can include places such as living areas, garages and workshops.

Step 2: Choose additional fire extinguishers (should have)

The kitchen is the most likely place where you will start a fire. Protect special places in your home with a UL-certified fire extinguisher.
