Exi Heat fire detector
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, namely:
TD-811Exi (thermal differential) responds to rapid temperature rise or maximum temperature of 55 ° C
TD-812Exi (thermal differential) responds to a rapid temperature rise or a maximum temperature of 64 ° C
TMD-811Exi (thermo maximum) only responds to a temperature of 55 ° C
TMD-812Exi (thermo maximum) only responds to a temperature of 64 ° C
