10 Year Photoelectric Smoke Alarm

Smoke alarms are one of the most essential accessories your home will ever need, but are often the last thing you think about! You spend hundreds of thousands of dollars buying or designing and building your dream home and then, reluctantly, install large and unsightly smoke alarms throughout – well, not any more!

Smoke Alarm Sounding

The Danish designed CAVIUS Photoelectric Smoke Alarm is a welcome change to the traditionally large and unsightly smoke alarms we have had for years. Using all the recommended technologies from both the New Zealand Fire and Emergency Service and global fire services, offering early detection of a home fire with a loud piercing audio alert when smoke is detected and it just looks great! Being so small and aesthetically pleasing you don’t mind placing it where it will work best – right in the centre of the room.

Don’t forget about our Thermal Heat Alarm – designed to detect fast, flaming  fires in the areas not suitable to install smoke alarms such as kitchens, garages, workshops, or laundries.

The CAVIUS 40mm 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 devices have a 30 day low battery warning, increasing your chances of identifying that your smoke alarms need to be replaced.

The intelligent multi function side button is the device’s test function; which unlike other smoke alarm brands, when the CAVIUS test button is pressed the audible and visible indicators are activated if the sensor is working properly. The intelligent button also functions as a hush button; during alarm, when pressed it will put the unit to sleep and the device will automatically reactivate after 10 minutes, allowing you time to clear the air. The side button contains an LED and emits a regular, dim low light flash to let you know the device is active and operating.

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. With a 10 Year long-life battery included, there is a lot to love about such a miniature alarm.

Cavius Smallest Smoke Alarms


Change your smoke alarm, not your battery

A smoke alarm should be one of the most essential additions in your home. Every year, the NZ Fire and Emergency Service attended over 3, 700 house fires. In over 80% of those fires, smoke alarms were either not installed or not working. The CAVIUS Smoke Alarm has you covered for 10 years and won’t become an eye sore in your home.

Cavius Home Starter Smoke Alarms


Protect your family

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.

Cavius Compliance Pack Smoke Alarms


Smoke alarms are a legal requirement

If you have built a new home then it will be a legal requirement to install up to three smoke alarms to gain your Code Of Compliance. We have made this easy by preparing a Compliance Pack just for this purpose. The Compliance Pack comes complete with three Photoelectric Long-life Smoke Alarms.


Never put a smoke alarm in the kitchen


You should never put a smoke alarm in the kitchen regardless of the type of alarm. Over time airborne cooking fats block any smoke alarm and prevent smoke from entering the sensing chamber, naturally impairing performance and function. Now there is a product for the direct kitchen area, the CAVIUS Thermal Heat alarm, for the fastest detection of flaming kitchen fires. Click the ‘VIEW MORE’ button below to find out more.
