Wireless Interlinked Battery Alarm Pack - 3 Smoke & 1 Heat

The Wireless Interlinked Battery Alarm Pack – 3 Smoke & 1 Heat provides reliable whole-home fire protection without the need for wiring.

This pack includes:

• 3 × DHI-HY-SA40A wireless interlinked smoke alarms

• 1 × DHI-HY-HT10A-R8 wireless interlinked heat alarm

A fully interlinked safety system suitable for 2–4 bedroom homes, rental properties and HMOs.

All alarms communicate wirelessly. When one unit detects danger, every alarm in the network sounds simultaneously, ensuring occupants are alerted throughout the property regardless of where the fire starts.

The smoke alarms use advanced photoelectric split-spectrum sensing to respond quickly to real fire conditions while helping reduce nuisance alarms from cooking fumes or steam.

The heat alarm features a high-precision thermistor with Class A1 detection (54°C to 65°C), making it ideal for kitchens, garages and other areas where smoke alarms are not suitable.

Each unit is powered by a sealed 10-year lithium battery, removing the need for mains wiring and reducing ongoing maintenance.
