Frequently Asked Questions

Why smoke detectors? Why not heat detectors?
Smoke and deadly gases tend to spread faster and farther than heat which is why an operating smoke detector is so important to have. More people die from the effects of smoke and deadly gases by a margin of 2 to 1. A smoke detector will automatically sound a warning when they sense smoke or other products of combustion. When people are warned early enough about a fire, they can escape before it spreads.
How many smoke detectors should I have?
At least one smoke detector near each sleeping area and one on each level of the home including the basement. If you sleep with the door closed, the detector needs to be installed inside the bedroom.
Where should I mount my smoke detectors?
Mount smoke detectors high on a wall or on the ceiling because smoke rises. If mounted on the wall, it should be 4 to 12 inches away from the ceiling. If mounted on the ceiling, it should be 4 inches from the wall. On a vaulted ceiling, be sure to mount the detector at the highest point of the ceiling. Place smoke detectors at the top of each stairwell and at the end of each long hallway. Remember, do not place them any closer than 3 feet of an air supply register that might recirculate smoke resulting in a delayed alarm. Be sure to keep the detector away from fireplaces and wood stoves to avoid false alarms.
How are smoke detectors powered?
Some smoke detectors are powered by a 9-volt battery, some are powered by the home's electrical system, and some are the combination of both. That is, they are wired into the home's electrical system and equipped with a 9-volt battery back-up.
Who should install my smoke detector?
If you purchase smoke detectors that are to be connected to your home's electrical system, you should have a qualified electrician install them. If you purchase those that are solely battery powered, you can install them yourself with a screwdriver and a drill according to the manufacturer's instructions.
What about maintenance?
Keeping smoke detectors in good condition is easy. Change the battery (if equipped) at least once a year or sooner if the smoke detector signals a low battery. Clean the detector face and grillwork often to remove dust. Test your smoke detector monthly. Replaced your detectors at least every 10 years. Always follow the manufacturer's instructions.
After they are installed, then what?
Test them and make sure they work. Everyone in your household should be aware of what they sound like and know what to do if they hear that noise.
How do I test my smoke detector?
Push the test button. If you test it with smoke, use a match or candle. Blow out the flame and let the smoke drift up into the smoke detector. Never test the smoke detector with a flame!
What is that chirping noise?
That noise, usually every 60 seconds or so, indicates the battery is going dead. This signals you to change the battery as soon as possible. That signal may last for a couple of days, but once the battery is dead you will have no protection at all.
How do I prevent that annoying false alarm?
If you are getting false alarms, try moving your smoke detector farther from the kitchen or bathroom area and closer to the bedroom area. There are smoke detectors on the market that are specifically designed for kitchen or bathroom area use. Regular smoke detectors are too sensitive for these areas and cause annoying false alarms.
