This FireAngel heat alarm is designed for areas where smoke alarms are not suitable, such as kitchens, garages, and attics. It features advanced thermistor technology to detect heat build-up from fires without false alarms from cooking fumes. The alarm is powered by a 10-year sealed, tamperproof lithium battery, eliminating the need for battery changes. It includes a large central test/silence button and a 'Sleep Easy' option to silence low battery chirps for 8 hours. The alarm provides an 85dB sound output and has an operating light that flashes to confirm it is powered. It is certified to BS 5444-2:2003 and is suitable for leisure accommodation vehicles.
