The CAVIUS Wireless Family Thermal Heat Alarm has been designed to be installed in areas where smoke alarms cannot. These areas are the kitchen, garage, workshop and laundry. The Thermal Heat alarm detects a rapid and constant change in heat, normally caused by flaming or flash fires. For all other areas a Wireless Family Smoke Alarm is recommended.

A thermal heat alarm should be one of the most essential additions in your home. Over 44% of residential fires start in areas you are unable to install smoke alarms, this is due to either airborne cooking fats in the kitchen or car fumes in the garage blocking any smoke alarm and prevent smoke from entering the sensing chamber.

The CAVIUS Wireless Family Thermal Heat Alarm uses new Radio Frequency technology to sync with other Wireless Family alarms in the house. This means when one of the alarms is activated, all other connected Wireless Family alarms will sound an alarm too. Everyone in your home, whether they’re upstairs, downstairs, or even in a separate wing of the house, will know immediately if there is a potential fire developing somewhere in the home. Keep everyone in the house accounted for and out of the house faster in the case of a fire.

The CAVIUS Wireless Thermal Heat Alarm comes fitted with a 5 year long-life battery. The process for syncing up your Wireless Family alarms is simple; set all your Wireless Family alarms into ‘LEARN/LINK’ mode, press the test button on one alarm which creates a ‘Master’ – the ‘Master’ sends out a unique code to all your other alarms. Place the alarms back into ‘NORMAL’ mode and you are ready to install.

Once installed with the simple ‘smart-clip’ ceiling mechanism, the alarm is activated. It has an audio alert output of 85 dB(A) at 3 metres, generating a piercing alarm designed to wake you from your sleep. The Wireless Thermal Heat Alarm also syncs with the Wireless Family Photoelectric Smoke Alarm.

CAVIUS devices have a 30 day low battery warning, increasing your chances of identifying that your smoke 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. A dim, low light flash will be emitted from the device to let you know the device is 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.
