Overview Features Technical Data FAQs Downloads & Resources

The WisuAlarm bundled packs combine modern design with advanced detection technology, offering a convenient way to purchase the right mix of products to protect your home.

All detectors are Grade D1 devices, mains powered with wired interconnection and sealed 10-year lithium backup batteries for long-term reliability.

These packs are suitable for new installations or upgrading existing properties where detectors are connected by a 3-core and earth standard mains cable.

Each pack includes:

2 x Mains Powered Lithium Battery Smoke Detectors (DHI-HY-SA5MA-V2) – designed with split-spectrum technology to deliver quick response to smoke while reducing false alarms. When smoke concentration reaches the alarm threshold, all interconnected units will sound until reset.
1 x Mains Powered Lithium Battery Heat Detector (DHI-HY-HT5MA-V2) – reacts rapidly to dangerous rises in temperature between 54°C and 65°C, triggering a continuous alarm across all linked devices until reset.
