Firex photoelectric smoke alarms respond to slow burning, visible smoke caused by smoldering fires.
Designed for use in kitchens and furnace rooms, they reduce nuisance alarms caused by cooking fumes
or high humidity. With installer focused innovations such as gasketless mounting, separate mounting
bracket as well as state-of-the-art production testing equipment, Firex photoelectric smoke alarms have
earned their reputation as the most preferred smoke alarms among contractors.
