The Family First Heat Alarm is a 9v battery operated alarm that uses technology that senses excessive heat or fire by air temperature rather than responding to smoke particles. The unit monitors heat and activates at 57°C (135°F) with an extra-loud alarm sound at over 85dB (at 3 metres). For maximum protection, install a heat alarm in each room, especially kids bedrooms, the kitchen, laundry and living rooms, stairwells and the garage.

Not sensitive enough to create trust that it will work in the kitchen. Tested the unit as per instructions. Failed to activate in front of hot heater airflow. Only activates if you put a naked Flame within 10 cm of sensor, to get it this close, it started to melt the housing around the sensor! If the fire gets that hot at the ceiling then it’s already too late
