Need to connect domestic smoke, heat and CO alarms to other equipment? The FireAngel WRLYM-1EU is a wireless interlink relay module that switches fire door holders, telecare and warden call systems when a Smart RF alarm activates.
The FireAngel Specification WRLYM-1EU is a mains-powered wireless interlink relay that connects a FireAngel Specification Smart RF network of smoke, heat and CO alarms to third-party systems such as fire door holders, telecare and warden call systems. It can differentiate fire and CO alarm signals and activate its relay contacts independently. Once installed, it is wirelessly interlinked to a mains-powered Specification smoke (SM-SN-1) or heat (HM-SN-1) alarm. A hardwire-only version (RLYM-1EU) is also available.
