Wireless Interlinked Battery Alarm Pack – 3 Smoke, 1 Heat with Gateway

The Wireless Interlinked Battery Alarm Pack - 3 Smoke, 1 Heat with Gateway provides complete whole-home fire protection with app connectivity.

This kit includes three WisuAlarm DHI-HY-SA40A wireless smoke alarms, one DHI-HY-HT10A-R8 wireless heat alarm, and the DHI-HY-GW01A wireless gateway.

All alarms are wirelessly interconnected, meaning when one alarm activates, every alarm in the network sounds together. This ensures occupants are alerted throughout the property, regardless of where the fire starts.

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

The smoke alarms use advanced split-spectrum photoelectric sensing to detect smoke quickly while reducing nuisance alarms. The heat alarm uses a high-precision thermistor with Class A1 detection (54°C to 65°C), making it ideal for kitchens, garages and areas where smoke alarms may be unsuitable.

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