Wireless Interlinked Battery Alarm Pack – 10 Smoke, 2 Heat with Gateway

The Wireless Interlinked Battery Alarm Pack – 10 Smoke, 2 Heat with Gateway is designed to provide comprehensive fire protection across large residential properties and multi-room rental homes.

This configuration is particularly well-suited to:

• Large detached homes

• Three-storey properties

• HMOs

• Student accommodation

• Guest houses or large holiday lets

The pack includes ten WisuAlarm DHI-HY-SA40A wireless smoke alarms, two DHI-HY-HT10A-R8 wireless heat alarms, and one DHI-HY-GW01A wireless gateway.

All alarms are wirelessly interconnected, meaning when one alarm activates, every alarm in the network sounds simultaneously. This ensures full-property alerting, no matter where the fire originates.

The included DHI-HY-GW01A gateway connects the system to your Wi-Fi network, enabling real-time push notifications through the WisuAlarm mobile app. If an alarm triggers, you receive instant alerts directly to your smartphone, whether you are at home or away.

The DHI-HY-SA40A smoke alarms use advanced split-spectrum photoelectric sensing to detect smoke quickly while reducing common nuisance alarms such as cooking fumes or steam.

The DHI-HY-HT10A-R8 heat alarms feature a high-precision thermistor with Class A1 detection (54°C to 65°C), making them ideal for kitchens, boiler rooms and garages where smoke alarms may be unsuitable.

All devices are powered by sealed 10-year lithium batteries, removing the need for mains wiring while delivering long-term, low-maintenance protection.
