Mercury HD-718 Heat Sensor Alarm with 10 Year Sealed, Battery Replacing and a Simple Install in Kitchens, Garages, linving Rooms and Lofts Alerts to Ra

Heat Alarm with 10 Year Sealed BatteryProvides 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.DetailsBatteries DC3V lithium battery (internal)Alarm output 85dB @ 3mSensor Electronic thermistorAlarm level 54°~70°CLifetime 10 yearsDimensions 116mm ?, 46mm heightWeight 116g
