Heat Alarm with 10 Year Sealed Battery

Provides a quick alert to rapid rises in temperature rather than smoke, making it perfect for kitchens as it won't react to cooking fumes. The Heat Alarm will sound when it detects extreme temperature rises created by chip pan fires for example. Ideal for areas with fumes and high humidity, such as kitchens, garages and lofts, the thermistor technology ensures you’re alerted to fires quickly without false alarms. The unit needs no battery maintenance, simply engage the internal battery using the switch on the base of the unit, fix to your desired surface and test on a regular basis. Once the detector nears the end of its 10 year life, a low battery indication alerts you to replace the unit.
