Power Supply Module for Smoke Ventilation Window
and Door Actuators
These modules make it possible to supply the actuator or group of actuators of fire
windows and doors, controlled by the change of polarization of the mains voltage. In order to
monitor the door or window status, the module can operate a potential-free contact of an
additional reed relay.
The connecting and switching functions in the power circuit are performed by relays
with monostable changeover contacts (NO and NC), e.g. RM84 or R4 type.

This module makes it possible to supply optical indicators, fire alarm sounders or strobe
light sirens connected in parallel. The module safety circuits are adjusted according to the
power and number of supplied signalling devices. The module may be adapted to 24 V DC or
230 V AC power supply.
