Smart RF Wireless Integration

When installed, the WRLYM-1EU wirelessly interlinks with FireAngel Specification mains-powered smoke alarms (SM-SN-1) or heat alarms (HM-SN-1). Using Smart RF technology, alarms communicate across the property so that when one alarm activates, all connected alarms respond simultaneously.

This relay supports wireless and hybrid alarm networks, offering a practical solution for retrofits and complex installations where running interlink cabling is not feasible. A hardwired-only relay option is also available for projects requiring fixed wiring.
