10 Year Thermal Heat Alarm

The Danish designed CAVIUS Thermal Heat Alarm is a game changer! Over 44% of residential fires start in areas you are unable to install smoke alarms, areas which normally have high levels of dust or fumes. These contaminants result in a build-up in the sensing chamber which can impair performance of a smoke alarm, regardless of type.


The CAVIUS Thermal Heat Alarm has been designed to warn of flaming fires in the areas not suitable to install smoke alarms; kitchens, garages, workshops or laundries.

By using state of the art technology, the Thermal Heat Alarm monitors normal and expected changes in ambient room temperature. If rapid and constant change of temperature increases, the Thermal Heat Alarm will sound.

The Thermal Heat Alarm detects flaming fires in not just one but two ways; to slowly developing flaming fires by using a fixed temperature setting and where rapid response to fire is vital, rate-of-rise is used.

The CAVIUS Thermal Heat alarms come fitted with a 10 year long-life battery. Once they are installed with the unique and simple “Smart Clip” ceiling mechanism, the battery is activated. They have an audio alert output of 85dB(A) at 3 metres, generating a piercing alarm designed to give you more time to react and respond or evacuate the home.

The multi-function intelligent top button is the device’s test and hush button. It will put the unit to sleep if you have caused a false alarm and the device will automatically reactivate after 10 minutes, allowing you time to clear the air. It also emits a regular, there is also dim low light flash to let you know the device is active and operating.
