FAQ and Installation Request
The Central Crossing Fire Protection District in conjunction with the Thrifty Closet, American Red Cross, and other private donations will provide and install smoke alarms upon request by homeowners. For more information on this contact us.
How do they operate?
There are two types of smoke alarms:
- Ionization – A radioactive material is used to ionize the air in the sensing chamber. Smoke entering the chamber activates the alarm.
- Photo Electric – Works much like an electric eye on an automatic door. When smoke enters the chamber, the electric eye sees it, which activates the alarm.
How are they powered?
- Battery – The easiest to install because they do not require any connection to the home’s electrical system. The challenge with these alarms is they require the battery to be replaced periodically for the unit to work.
- A/C Hard Wired without battery – These alarms are wired directly to the homes electrical system. These alarms do not operate if there is a power outage.
- AC hard Wired with battery backup – This is the best way an alarm can be powered. If the battery dies, it will still be powered by the home’s electrical system. And if there is a power failure, the battery will continue to operate the alarm.
How and where should they be installed?
Follow the manufacturer’s recommendations on proper placement. Avoid areas within 6-inches from where the ceiling meets the wall. The smoke will rise along the wall and curve to the ceiling delaying or never activating the smoke alarm.
What is the proper maintenance?
- Check the power supply once a month once by pressing the test button.
- Change the battery at least twice a year (when you change your clock-change your battery).
- Remove cobwebs, insect, or dust by vacuuming at least every six months.
What is the life span of a smoke alarm?
Smoke alarms should be replaced every ten years. Smoke alarms should also be replaced when they beep periodically and cannot be corrected by replacing the battery or vacuuming to remove the dust and cobwebs.
Did You Know...
