The CAVIUS Thermal Heat Alarm has been designed to detect fast, flaming fires in the areas not suitable for 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.

Our 10 Year Photoelectric Smoke Alarm is ideal for places where smoldering 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 multi-function side button contains an LED. This intelligent button is the device’s test button as well as the hush or pause button. It will put the unit to sleep if you have caused a false alarm and the device will automatically reactivate after 10 minutes. It also emits a regular, dim low light flash to let you know the device is active and operating.

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.
