The GT Wireless Interconnected Heat Alarm is specifically designed to continuously monitor abnormal temperature. Integrated with a high-precision thermistor and an intelligent algorithm, it triggers an alarm when a predetermined temperature is reached. It is ideal for smoky, dusty, or humid areas that may trigger false smoke alarms, e.g., kitchens where cooking fumes are present and attics, garages where there may be lots of dust. The GT High Performance Heat Alarm is 240v mains powered with a 9v battery backup. It provides 24/7 protection against fire and the alarm signal will be pushed to every alarm in the interconnected network and they will raise the alarm in unison.
