10 Year Thermal Heat Alarm

The Danish-designed CAVIUS 10 Year Thermal Heat Alarm is a game changer! Over 34% of residential fires start in areas you are unable to install smoke alarms, areas which normally have high levels of dust, fumes, or cooking fats. These contaminants result in a build-up in the sensing chamber which can impair performance of a smoke alarm, regardless of type.

CAVIUS Thermal Heat Alarm

The CAVIUS Thermal Heat Alarm has been designed to detect fast, 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.

A heat alarm should not replace smoke alarms – our 10 Year Photoelectric Smoke Alarm is ideal for places where smouldering fires are likely to develop – places such as the hallway, bedroom, and lounge.


The 40mm 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.

CAVIUS devices have a 30 day low battery warning, increasing your chances of identifying that your alarms need to be replaced.

The intelligent test and 10 minute hush button is embedded in the bottom surface of the alarm for easy access. When the test function is pressed, which unlike other smoke alarm brands, the alarms audible and visible indicators are activated if the sensor is working properly. During alarm stage, if the hush function is pressed it will put the unit to sleep and the device will automatically reactivate after 10 minutes, allowing you time to clear the air.

Aesthetically pleasing CAVIUS alarms suit any new home, refurbishment and areas of your home like the kitchen, garage or laundry where you want your alarm to be almost invisible. With a 10 Year long-life battery included, there is a lot to love about such a miniature alarm.
