I’d like to replace the smoke detectors in my home with models that I can see in SmartThings (that is, the First Alert ZSmoke). I didn’t realize until I went to put the unit up that the existing smoke detectors are hardwired. I guess I never thought about it because the backup battery needed to be replaced once a year, anyway.
Are there any disadvantages to going to a battery-only unit? Could I just cut the power, cap and tape the wires, and put them in the ceiling? I read in the installation instructions that one shouldn’t replaced a wired thermostat with a battery thermostat because the air flow can cause it to not detect smoke properly… could I simply cut a piece of cardboard to put between the thermostat and the hole?
Would it be best to return these smoke detectors and wait for a wired version to come out?
