Wisualarm DHI-HY-GC30A-R8 Wireless Interconnected Carbon Monoxide Detector with LCD Display

In a family home, the Wisualarm DHI-HY-GC30A-R8 stands guard against the silent threat of carbon monoxide. This wireless interconnected CO detector uses an electrochemical sensor to provide early warning of dangerous CO levels, with a loud 85 dB alarm and a clear LCD display showing real-time concentration. It can link up to 20 units via 868.3 MHz radio, so when one alarm triggers, all connected detectors sound together—ensuring everyone in the house is alerted, even in distant bedrooms. Powered by three replaceable AA batteries, it offers up to three years of operation and a 10-year device lifespan, making it a reliable, low-maintenance safety solution.

Why choose it

This detector goes beyond basic CO alarms with its wireless interconnection capability. In multi-room homes or small businesses, linking up to 20 units creates a comprehensive safety network—if CO is detected in the basement, the alarm sounds in the bedroom upstairs. The LCD display provides at-a-glance status, and the replaceable batteries mean no hardwiring is needed. Certified to the latest European standards, it offers peace of mind with a 10-year lifespan and low maintenance.

Ideal use cases

• Residential homes, especially with multiple floors or bedrooms
• Small offices, workshops, or rental properties
• Areas with fuel-burning appliances (boilers, fireplaces, gas stoves)
• Garages or utility rooms where CO may accumulate

Good to know

The detector includes a test/silence button for regular checks and false alarm control. An end-of-life indicator alerts you when the 10-year sensor life is up. The ABS plastic housing is durable and suitable for wall or ceiling mounting. Batteries are included, and the unit is ready to use out of the box.
