Smoke Alarm Beeping in Residential Property
A smoke alarm may beep every 30 to 60 seconds or so when something is wrong. This could be an indication the battery is low or there is a dust particle build up in the alarm causing a false reading. Usually the problem is resolved by replacing the battery with a new one. As well, you can try and dust/vacuum around the alarm (as you should do every so often).

If the alarm continues to beep after battery replacement then the device may need to be replaced. If the smoke alarm is easily activated by cooking or showering, you may want to move it or replace it with a different type of smoke alarm. Smoke alarms can use ionization or photoelectric technology as well as a combination of both technologies in one alarm. If you are unable to replace the unit yourself, and you currently have at least one working smoke alarm in your home, you may schedule a free home evaluation. FRS may also provide assistance with the installation of battery powered smoke alarms or batteries at that time of the visit. If you have an alarm that is wired into your homes electrical power, you will need to have a licensed, bonded, and insured electrician handle this.

If you have no working smoke alarms in your home, please tell your MC311 representative or contact your closest fire station for assistance with having one installed immediately.
