Heat Alarms respond to fire, not smoke. While Smoke detectors get all the attention, heat detectors are another useful component of any modern fire detection system. Some environments can trigger nuisance alarms in conventional smoke alarms due to shifts in temperature and humidity as well as dust, fumes and insects. Heat alarms are intended for use in locations where standard smoke alarms are not suitable because they are virtually unaffected by these adverse conditions. Heat alarms are useful in Kitchens, Unfinished Attics, Basements, Garages, Boiler Rooms and other areas where high levels of dust and fumes are present.

DO NOT install heat alarms in areas with high humidity, like bathrooms or areas near dishwashers or washing machines, air returns, heating and cooling supply vents, fans, decorative objects, window molding etc. that may prevent heat from entering the unit thus interrupting its alarm. Also do not install in rooms where temperatures may fall below -10 degrees F or rise above 100 degrees F or near fluorescent lights - electrical noise and flickering may affect the alarm’s operations.
