HispecHIRFLBHE (HSA/BH/RF10-PRO) heat alarm

The Hispec HIRFLBHE (HSA/BH/RF10-PRO) is a battery-powered heat alarm designed to sound when temperatures rise. It’s for places such as the kitchen or a garage, where smoke from cooking or fumes from a vehicle could cause false alarms with traditional smoke alarms. It comes with a sealed lithium battery, which means you’ll never need to replace it over the 10-year life of the device. It’s a linkable model that can be wirelessly paired with other devices – such as the Hispec HIRFLBSM smoke detector – so that if any module detects danger they will all sound together. This means it's suitable for homes in Scotland following the 2022 smoke and heat alarm law changes. But is it any good at detecting rises in temperature? To find out, we tested it in the lab.
