Mercury: 350.130UK, Heat Alarm with Electronic Thermistor, 10 Year Battery
About this product
The Heat Alarm with a 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. This alarm will sound when it detects extreme temperature rises created by chip pan fires, ensuring you’re alerted to fires quickly without false alarms.
Ideal for areas with fumes and high humidity, such as kitchens, garages, and lofts, the thermistor technology ensures reliable performance. The unit requires no battery maintenance: simply engage the internal battery using the switch on the base, fix it to your desired surface, and test regularly. A low battery warning indicates when the unit needs replacing, signalling the end of its 10-year life.
