Addressable relay module is a programmable device. It is configured by the user when configuring the system from a computer or from a control and indicating device.

Relay module is a remotely operated switch. Functionally, relay module OM4 represents four separate logical units (four separate relays) each having its own address in the system.

Addressable relay module allows connection of any actuators of PCS which can be controlled on relay level, provided their current and voltage meet the technical characteristics of the relay. Besides, relay module enables transmission of different system states to external equipment and central monitoring console.

Relay module has LED indication of communication with control and indicating device and indication of the activated state of the relay.

Address mark power supply as well as signals transmission to receiving and controlling device is realized via a unipolar communication line.

Relay module OM1, OM4 may be installed in DIN rail using special securing bar (not in the scope of supply; may be provided by separate order).

Relay activation can be caused by different events in the system (zone), e.g., fire, warning, activation of fire-suppression module automatics, alarm, arming, disarming, lamp, devices actuation (AM-1T, MDU-1, ShUZ) etc.
