MHY 734.031

The MHY 734.031 base is intended for connection with automatic fire detector LITES to control other equipment, eg fire shutter. The base is supplied with 24 V. AC or DC voltage. The voltage is rectified and stabilized to supply the detector. If the detector is activated to the alarm state, the relay closes in the socket. The independent changeover contact of the relay can be used to control eg a fire shutter. The reset is performed by disconnecting the power supply.
