WisuAlarm Wireless Alarm Control Unit

The DHI-HY-RC20A-R8 Wireless Interconnected Alarm Control Unit provides centralised control and visual indication for WisuAlarm wireless smoke, heat and carbon monoxide alarms.

Once paired, the control unit remains continuously connected to all linked alarms, receiving real-time fire, carbon monoxide and fault signals from across the property. When an alarm activates, the unit provides a clear visual alert, helping occupants quickly identify that an alarm has been triggered.

Individual indicator lights clearly show fire, CO and fault conditions, making it easy to understand the type of alert at a glance. This is particularly useful in larger homes or properties with multiple alarm types installed.

The unit allows all interlinked alarms to be tested from one central location, removing the need to visit each alarm individually. A locate function helps identify the initiating alarm by silencing all other devices, while the silence function allows all interlinked alarms to be muted when appropriate.

Designed for residential use, the control unit is suitable for houses, apartments and similar domestic settings. It supports wireless interconnection with up to 24 compatible WisuAlarm devices, providing flexible whole-home coverage.

Powered by a sealed 10-year lithium battery, the unit requires no wiring and minimal maintenance. It can be wall mounted or used free-standing, allowing it to be positioned in a convenient and accessible location within the property.
