Product overview

If you have moved into an existing home one of the first things you should do is check the smoke alarms. If you need to install smoke alarms or the existing alarms have expired, the Home Starter Pack is a great place to start. This pack is the minimum you should have in your home, containing two Photoelectric smoke alarms and one thermal heat alarm, all with long-life batteries.

The Danish designed 40mm CAVIUS Smoke 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 wake you from your sleep. CAVIUS uses the highly recommended photoelectric technology which reduces false alarms considerably, yet provides the earliest detection of smoke presence. All of our alarms are 100% tested in world leader AWT’s tested tunnels. Aesthetically pleasing CAVIUS alarms suit any new home, refurbishment and areas of your home like the bedrooms, lounge and hallway where you want your alarm to be almost invisible.

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

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.

Stylish and state of the art, they're the ideal way to keep your home and family safe, order yours today.

Hi, We have high roofs. How do we turn off any false alarms without a ladder?
To turn the alarm off you need to press the hush button for 2 seconds (which is the entire bottom of the alarm), if you have high ceilings you will need a ladder.

What is the difference between the smoke alarm and the heat alarm? Which areas are each recommended for? ie is one designed for the bedrooms and one in the kitchen?
Smoke alarms are intended to protect people as well as property by generating an alarm in the earlier development of a fire whereas heat detectors are intended to minimize property damage by reacting due to the change in temperature which is caused by a fire. Smoke alarms are suitable for all rooms where a fire might start. However due to the smoky nature of kitchens, a heat alarm is better suited.

Are the cavius alarms in the 3 pack the ones that all connect to each other? If so, if you buy multiple packs can they all still connect to each other?
These are just the individual units. We do sell the Cavius 10 Year Wireless Family Photoelectric Smoke Alarm - which can have up to 32 alarms connected together.
