Fixed-temperature thermal detector TM 3-M

This VdS-approved fixed-temperature thermal detector triggers an alarm when a certain temperature value is exceeded. In this case, it indicates the alarm via a red LED and reports it to the SHEVS Control Centre.

The detector can be easily and quickly mounted on a standard or relay base thanks to its quarter-turn fastener. It has sabotage and extraction protection and is insensitive to wind and air pressure.

Due to its flat and compact design, it can also be mounted in confined areas and blends inconspicuously into its surroundings.
