Wireless Heat Alarms With 10 Years Battery

Safeguard residential, rental and hospitality premises with our RF wireless interconnected heat alarm fully compliant with BS5446-2:2003, an essential fire safety device specially designed for kitchens, garages and utility rooms where smoke detectors often trigger unwanted false alarms.

This heat detector adopts a sealed non-replaceable 3V lithium battery as its sole power source, delivering a full service lifespan exceeding 10 years. The integrated power design eliminates frequent battery replacement work, cutting long-term maintenance costs for homeowners, property managers and hotel operators. No regular battery purchase or replacement operation is required throughout its whole service cycle, bringing great convenience to long-term property management.

In terms of alarm performance, the unit produces a loud alert volume of ≥85dB measured at 3 meters, loud enough to wake sleeping residents and alert people across multiple connected rooms. A large prominent test button is fitted on the front panel, enabling simple weekly function checks to confirm normal operation without complicated steps. It features an 8-minute silence mode to temporarily mute nuisance triggers during high-temperature cooking work. When the battery power runs low, a unique 14-hour non-disturbance function suppresses the intermittent low-battery beeps overnight, avoiding sleep disruptions for users.

Equipped with an optional built-in RF wireless module, the heat alarm supports wireless interconnection of up to 40 units. Once one detector senses abnormal temperature rises, all paired linked alarms across the whole building will sound simultaneously, achieving full-space instant fire early warning for multi-storey houses, apartment blocks and holiday rentals.

With a compact dimension of Φ120mm*46.5mm, it is exclusively designed for ceiling installation. The matched rotary mounting bracket allows quick, tool-free installation and disassembly. Simple structure, stable temperature sensing and full UK standard certification make this long-life interconnected heat alarm a reliable, cost-effective mandatory fire safety solution for all British domestic and commercial living spaces.
