Thermal detector TD81x/TMD81x

In the event of a fire, the thermal fire alarm responds to the set threshold or rapid temperature rise. In the event of a fire, an increased current flows through the detector, thus informing the fire control panel of the occurrence of a fire. We produce several types of thermal detectors:

TD-811 (Thermal Differential) responds to a rapid temperature rise or a maximum temperature of 55° C

TD-812 (Thermal Differential) responds to a rapid temperature rise or a maximum temperature of 64° C

The TMD-811 (thermo maximum) only responds to a temperature of 55° C

The TMD-812 (thermo maximum) only responds to a temperature of 64° C
