Thermal locks for fire doors


Generally Sliding fire doors are installed in underground car parks. Of course in the case of fire these must be closed in order to stop fire from spreading.

In order to provide emergency exits for people using the car park, separate pedestrian fire doors are also installed next to the sliding doors.

The thermo lock is suitable for the reliable control of both single and double pedestrian fire doors.

Bimetal technology advantages:

  • Can be used as both thermal-sensor and actuator.
