Wireless Interlinked Battery Alarm Pack – 5 Smoke with Gateway

The Wireless Interlinked Battery Alarm Pack – 5 Smoke with Gateway provides full-property smoke detection with real-time mobile alerts and remote monitoring capability.

This kit includes:

• 5 × DHI-HY-SA40A-R8 Wireless Interlinked Smoke Alarms

• 1 × DHI-HY-GW01A Wireless Internet Gateway

All smoke alarms are wirelessly interconnected, meaning when one alarm detects smoke, every alarm in the property sounds simultaneously. This ensures occupants are alerted wherever they are in the building.

The included gateway connects the alarm system to your Wi-Fi network, enabling instant push notifications through the mobile app. If an alarm activates, you receive real-time alerts directly to your smartphone, whether you are at home or away.

This pack is ideal for larger homes, multi-storey properties, rental properties, HMOs and holiday lets where whole-home coverage and remote awareness are essential.

Each alarm is powered by a sealed 10-year lithium battery, removing the need for wiring while delivering long-term protection with minimal maintenance.
