Heat Alarms

Heat Alarms

Heat alarms are designed for installation in smokey or dusty environments such as kitchens or garages, as they will not false fire alarm due to cooking fumes or emissions from a car exhaust. Heat alarms detect a rise in temperature beyond a trigger level and some heat alarms even measure the speed of the temperature rise. We also offer a heat alarm specifically designed to monitor the area above a cooker to detect if an oven ring has been left on or a pan dries out (innohome stove alarm).
