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

Relay module is a remotely operated switch.

Addressable relay module allows connection of PCS any actuators 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 indicating the communication with control and indicating panel and indication of the activated state of the relay.

Addressable mark power supply as well as signals transmission to receiving and control panel is realized via a unipolar communication line.

The OM4 relay module 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-extinguishing module automatics, alarm, arming, disarming, lamp, devices actuation (AM-1T, MDU-1, ShUZ) etc.
