Apollo Orbis Marine Relay Base (ORB-RB-40004-MAR)

Apollo Orbis Marine Relay Base (Part No. ORB-RB-40004-MAR)

The Apollo Orbis Marine Relay Base (ORB-RB-40004-MAR) is designed to provide switching capability for ancillary equipment within marine fire detection systems. The base uses a single pole voltage free changeover contact to switch and control ancillary equipment when a connected detector enters an alarm condition. When the detector activates, the relay energises and changes the contact state, keeping this condition until the detector is reset. This enables reliable control of external devices such as alarms, door releases, shutdown systems, and other interfaced equipment.

Designed specifically for demanding marine environments, the ORB-RB-40004-MAR combines a low-profile design with installer-friendly features that simplify wiring, commissioning, and maintenance while ensuring dependable long-term performance.
