Wireless Interlinked Battery Alarm Pack - 2 Smoke, 1 Heat & 1 CO

The Wireless Interlinked Battery Alarm Pack delivers whole-property protection from fire and carbon monoxide in a single, wire-free solution.

Designed for smaller residential layouts, this kit is well suited to 2–3 bedroom houses, flats, rental properties and holiday accommodation.

It is particularly appropriate for homes with gas boilers, open fires or other fuel-burning appliances where carbon monoxide monitoring is essential.

The system integrates smoke detection, heat detection and CO monitoring into one interconnected network.

If any single unit activates, every alarm in the property sounds simultaneously, helping to ensure occupants are alerted wherever they are.

The smoke alarms utilise split-spectrum sensing technology to improve response to both fast-flaming and smouldering fires while reducing nuisance activations.

The heat alarm provides Class A1 performance, making it suitable for kitchens, garages and other areas where steam or cooking fumes could trigger a smoke alarm.

The carbon monoxide alarm incorporates a precision electrochemical sensor designed to detect CO accurately and respond promptly to developing risks.

Each device is powered by a sealed 10-year lithium battery, removing the need for mains wiring and supporting long-term, low-maintenance protection.
