Summary
The Wisualarm DHI-HY-MRF60-R8 turns a standalone mains-powered alarm head into part of a fully wireless interconnected system, saving you from running interconnect cable between alarms on retrofit and multi-room jobs. Once fitted, the alarm can communicate with other WisuLink and WisuLink Pro devices over an RF mesh, so a trigger on one unit sounds every linked device on site.

For you on site, that means less time chasing cable routes through lofts and stud walls, and a simpler quote for properties where cabling is impractical or disruptive. The module plugs straight into the back of a compatible Wisualarm alarm head and draws its power from it, so there’s no separate power supply or additional wiring to commission.
A network of up to 24 WisuLink RF devices can be linked this way, with a flashing red LED confirming RF transmission and a flashing blue LED confirming a successful interconnect, giving you a clear visual check during commissioning.
Features
- RF mesh interconnected architecture – signal hops between devices rather than relying on a single weak link, improving reliability across larger properties
- Plug-in module design – fits directly onto the back of a compatible alarm head with no extra wiring or tools needed on site
- Powered from the alarm head – no separate power supply, battery or mains connection to commission or maintain
- Up to 24 WisuLink RF devices per network – supports multi-room and whole-house interconnect without running cable
- Dual-colour status indicator – flashing red confirms RF transmission, flashing blue confirms a successful interconnect, making commissioning checks quick and visual
- Long open-area RF range – up to 1000 metres in open, interference-free conditions gives flexibility across larger or spread-out sites

FAQ
The DHI-HY-MRF60-R8 is designed as an add-on for Wisualarm mains-powered alarm units and plugs directly into a compatible alarm head. If you’re working from an older installed base, check the specific alarm head model supports this plug-in module before ordering. The module has a built-in RF visual indicator: a flashing red LED shows RF transmission is active, and a flashing blue LED confirms the device has successfully joined the interconnected network. This gives you a straightforward visual check on each unit without needing separate test equipment. No, the module is powered entirely from the alarm head it’s fitted to, so there’s no separate power supply, battery or additional cabling to install. It’s a genuine plug-in fit, which is a large part of the time saving on retrofit jobs. Up to 24 WisuLink RF devices can be interconnected within a single mesh network. For larger sites, plan your device count and layout before installation to stay within this limit. The datasheet states up to 1000 metres in open, interference-free conditions, but real-world range will be reduced by walls, floors and other RF interference. For multi-storey or obstructed layouts, it’s worth testing signal strength between devices during first fix rather than assuming the full open-area figure. The datasheet lists CE, UKCA, PSTI and RCM certifications but does not reference BS 5839 compliance directly. If you need to confirm suitability for a specific commercial or domestic fire compliance requirement, check this against the full Wisualarm alarm head documentation or with the manufacturer before specifying.Will this module fit any Wisualarm alarm head?
