Some of the newer smoke alarms can use lithium batteries. While lithium batteries usually cost more, they last much longer - as much as five to seven years longer than a 9 volt battery.
Currently, smoke alarms are produced that use both ionization and photoelectric sensors. These “dual sensing” alarms offer better protection for your family. Several of the dual sensing models can also use long-life lithium batteries.
Using a dual sensing smoke alarm with a lithium battery offers the safest protection for you and your family.
Where to install smoke alarms
The Phoenix Fire Department recommends that every home have a smoke alarm outside each sleeping area and on every level of the home including basements. For the most protection, install a smoke alarm in each bedroom.
Hallways longer than 30 feet should have a smoke alarm at each end.
Install smoke alarms at the top of each stairwell.
Smoke alarms in kitchens should be kept away from cooking fumes or smoking areas.
Install smoke alarms on walls at least 12 inches from the ceiling.
Smoke alarms can be installed on ceilings but be kept at least 18 inches away from dead air space near walls and corners.
Where smoke alarms should not be installed
Do not install smoke alarms near fireplaces and wood stoves. This will cause “false alarms”.
Drafts can affect how the smoke alarm works, so avoid windows and doors.
Never place a smoke alarm closer than three feet from an air register that could recirculate smoke.
Do not install smoke alarms in laundry rooms or garages.
Take care of your smoke alarms
Vacuum your smoke alarms every month.
Never paint your smoke alarms.
Replace batteries when you hear a chirping, popping or beeping sound.
Smoke alarms should be replaced every 10 years. Check manufacturer’s instructions when purchasing any smoke alarm.

Get it! Purchase the correct number of smoke alarms you need for your home.
