Wireless Interlinked Battery Alarm Pack – Smoke, Heat & CO with Gateway

The Wireless Interlinked Battery Alarm Pack – 1 Smoke, 1 Heat & 1 CO with Gateway provides complete fire and carbon monoxide protection with app connectivity.

Suitable for flats, smaller homes, rental properties and holiday lets, this pack delivers protection in key risk areas while enabling remote monitoring.

The pack includes:

• 1 × DHI-HY-SA40A Wireless Interlinked Smoke Alarm

• 1 × DHI-HY-HT10A-R8 Wireless Interlinked Heat Alarm

• 1 × DHI-HY-GC20D-R8 Wireless Interlinked CO Alarm

• 1 × DHI-HY-GW01A Wireless Gateway

All alarms are wirelessly interconnected. If one alarm activates, all linked alarms sound together, ensuring occupants are alerted throughout the property.

The DHI-HY-GW01A gateway connects the system to your Wi-Fi network, providing instant push notifications via the WisuAlarm mobile app. If an alarm triggers, you receive real-time alerts directly to your smartphone.

The smoke alarm uses split-spectrum photoelectric sensing to respond quickly to smoke while reducing nuisance alarms.

The heat alarm uses a high-precision thermistor with Class A1 detection, making it ideal for kitchens and garages where smoke alarms may be unsuitable.

The carbon monoxide alarm uses a high-performance electrochemical sensor for accurate detection of CO from boilers, gas appliances and solid fuel systems.

All alarm devices are powered by sealed 10-year lithium batteries, removing the need for mains wiring and providing long-term protection with minimal maintenance.
