WisuAlarm Wireless Interconnected Relay Module

The WisuAlarm DHI-HY-MO5MA-R8 Wireless Interconnected Relay Module enables wired devices to communicate with compatible WisuAlarm wireless interconnection products, providing a simple way to expand and integrate domestic fire alarm systems. Supporting wireless interconnection of up to 24 compatible devices, the module allows alarm signals to be shared across the network, improving notification throughout the property.

When used alongside the WisuAlarm Wireless Gateway, the relay module enables real-time alarm notifications through the WisuAlarm app, providing remote awareness of alarm events.

A built-in dry contact input allows alarm signals from third-party devices to be received, while dual normally open (NO) and normally closed (NC) volt-free outputs provide flexible integration with compatible equipment. The module is also capable of distinguishing between smoke, heat and carbon monoxide alarm signals.

Designed for dependable operation, the DHI-HY-MO5MA-R8 is powered from a 100-250V AC mains supply and includes a built-in rechargeable 9V lithium backup battery to maintain operation during mains power failure.

Operating on the 868MHz wireless frequency with a transmission range of up to 1,000 metres in open, interference-free environments, it provides reliable wireless communication across compatible WisuAlarm systems.

Its compact wall-mounted design makes installation straightforward, while low standby power consumption helps maximise backup battery performance. Suitable for new installations and system upgrades, the relay module provides an effective solution where wired alarm outputs need to be integrated into a WisuAlarm wireless interconnection network.
