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.

Q:
Hi, I have already got these Smoke/Heat alarm for about 3yrs. I know this alarm last up to 10yrs. After 10yrs can their change battery or do we have to get new ones? Thanks
A:
The batteries are not replaceable for both alarms in the pack and you will need to replace them after 10 years.

Q:
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?
A:
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.

Q:
Can they be mounted on a sloped ceiling or vertical wall?
A:
They can be installed on a sloped ceiling, it is not recommended to install on a vertical wall though as these sensors are more effective when they are ceiling mounted

Q:
Hi, We have high roofs. How do we turn off any false alarms without a ladder?
A:
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.

Q:
I note that the long-life batteries are sealed. Does that mean that when they go flat they can not be replaced and the whole unit needs to be replaced?
A:
Yes that's correct the batteries cannot be replaced, these batteries have a 10 year lifetime and after that the alarm needs to be replaced..

Q:
Where is the best placement in bedrooms where one has HRV fan
A:
It is always best practice to install a smoke alarm on the ceiling and the more central in the room, the better. You want the smoke alarm to be installed at least 500mm away from any ceiling fan, air conditioner, heat pump or HRV system.

Q:
How easy are they to install?
A:
They are very easy to install, they have a 'Smart Clip' ceiling mechanism that needs to be screwed into the ceiling, the alarm is then twisted into the 'Smart Clip' mounting base.

Great product, great service

Second time buying Cavius

I had the wireless ones in a previous home; these are even smaller. No false alarms like we've had with other brands; put them too close and you'll know about it if you get a good sear on your steak though, so they definitely work. Only alarms I'll buy, others are rubbish.

AB Taranaki
Neat, tidy. Fit & forget

Great alarms, I have them in my workshop, and gifted a set to the kids. Neat and tidy, fit and forget

Awesome product

Eva Taranaki
Small, tidy, easy to install

Does what it says on the box so far. Had them a month or two no drama still working

River Taumarunui
Alarm starter pack

Small and compact and unintrusive when installed with a built in battery of a 10 year life span. Easy to install - two screws then clip in alarm to activate.

Mike Waikato
Easy Installation

Found it easy to install and ear peircingly loud!

Jenna Coromandel
Cavius Nano

Nice and easy to install, worth the money

Andrew Auckland
Easy to install

They're easy to install and are a tidy design. The heat alarms are a great idea for the kitchen and laundry.

Tessa Canterbury
Inconspicuous units

I have been wanting to swop to these little devices for some time now so glad they came up on Trade Tested. Again a big tick from me. The units come with ether surface fixing or recessed fixings, another nice feature..
