How to Remove Fire Alarm Systems in Your Home

Updated February 21, 2017

If you are moving or want to replace your fire alarm system, you must first remove the existing fire alarm. Fire alarm devices are often stand-alone units that run on a battery but can also be wired to an electrical system and outside alarm service. Inspect the wires, battery and wall mount brackets to properly remove a fire alarm system from your home.

Call the external monitoring system company to disconnect your fire alarm service.

Unplug the device. Use a step ladder to reach the fire alarm. If your fire alarm system has a direct wire to an electrical line, remove the fuse or shut down the circuit breaker. You may have to cut existing wires in the main control unit with a pair of wire cutters. The alarm system also includes a device called a sounder that sounds when the alarm is activated and tripped. The sounder can be placed indoors or outdoors and can be removed by unscrewing it from the wall mount or bracket.

Remove the batteries. Use a screwdriver to remove the backing of the battery compartment. Pull the batteries out.

Remove the control unit for the fire alarm from the wall brackets. Unscrew the brackets from the wall and pop the alarm off.
