55000-193 Apollo Alarmsense (2 Wire) High Temperature Heat Sensor

 

Apollo

55000-193

The heat sensor operates by using a matched pair of thermistors to sense heat.
One thermistor is exposed to the ambient temperature, the other is sealed.
In normal conditions the two thermistors register similar temperatures, but on the developement of a fire,
the temperature recorded by the exposed thermistor will increase rapidly,
resulting in an imbalance of the thermistors and causing the detector to change to the alarm state.
A High Temperature sensor has a fixed upper limit, which would be suitable for places such as kitchens.

AlarmSense sensors must be mounted on AlarmSense bases (45681-244)
