Fire Angel Heat Alarm Mains powered - HM-SN-1

The FireAngel HM-SN-1 is a 230V mains powered heat detector, with tamper-proof sealed for life battery backup and hard-wired interlinking capabilities. Under typical usage conditions, it uses approximately 10% less power than the average AC fire alarm, and has a battery life of 10 years.

Its integrated ultra-slim mounting base ensures easy installation in areas such as kitchens, garages, or lofts—areas where smoke alarms would be unsuitable due to high levels of fumes or dust.

Normal smoke alarms are unsuitable for use in kitchens due to the amount of false alarms activations from the likes of burnt toast. Our Thermistek heat alarms have a patented heat dish to target radiated heat directly onto the heat sensor for a faster reaction to potential fire risk. Wirelessly interconnect up to 50 Smart RF devices within 35m.

Heat alarms are best suited to areas where dust, fumes and moisture can cause nuisance alarms in smoke alarms.
