FireShield Mains Powered Smoke Alarm with 10 Year Lithium Battery

The WisuAlarm Mains Powered Smoke Alarm (DHI-HY-SA5MA-V2) combines advanced split-spectrum detection with a long-life rechargeable 10-year lithium backup battery, delivering reliable fire protection for domestic homes, holiday properties and private lets.

The alarm can be used as a standalone unit or hardwired to up to 24 other WisuAlarm smoke and heat detectors. With the optional WisuLink wireless module, it can also form part of a hybrid system, linking wired and wireless devices together.

If one alarm activates, all interconnected units will sound with an 85 dB alert for full coverage.

The clear advantage of WisuAlarm technology is fast smoke response with reduced false alarms. The detector features a built-in high-volume sounder, central test and hush button, and a low-maintenance design.

Unique to the range, the alarm can also be silenced using any infrared TV remote control.

Pairing the wireless module with the Internet Gateway allows users to receive notifications, view status and check remaining battery life directly via the free mobile app.
