Basic Functions

Especially good at detecting flames, slightly less effective at detecting smoldering fire. Heat from cooking or a steamy shower may set it off.

Special Features
Activates automatically when attached to its tamper-resistant mounting bracket, then keeps going for 10 years. A hush button silences nuisance alarms for 7 minutes. You cannot disconnect the sealed batteries.
