The next generation of heat alarms

Thermal Heat Alarm

40mm, Battery Operated

The CAVIUS 10-year Thermal Heat Alarm detects fast, flaming fires in kitchens, garages, workshops and laundries, and keeps you and your family safer.

Using state-of-the-art Danish technology, the Thermal Heat Alarm monitors changes in ambient room temperature and sounds if there is a rapid, constant temperature increase. It is also the world’s smallest heat alarm at just 40mm.

If rapid and constant increase of temperature occurs or ambient  temperature reaches >58°C, the alarm will sound.
