My smoke alarm keeps alarming, but there is no smoke?

First you can press the hush button on your alarm, this will pause the alarm for 10 minutes. 95% of the time, false alarms can be alleviated with some simple maintenance.  Dust or insects can enter the smoke chamber and cause false alarms, this can be solved by vacuuming around the mesh chamber on a low setting.

The other reason for false alarms maybe humidity or the location is too close to the bathroom, steam will set off all smoke alarms. In this case, its best to relocate the smoke alarm away from the bathroom.

How to test and maintain my smoke alarm?

After installation, its best practice to test your alarm by pressing the test button (this is the entire bottom surface of the alarm). You may need to wait 8 seconds for the alarm to power up.

To maintain your smoke alarm, vacuum around the smoke chamber regularly. Dust may accumulate inside the mesh even if it looks clean outside.
Do not use water or households’ products to clean your product.

How many smoke alarms do I need?

CAVIUS and the New Zealand Fire & Emergency Service recommend one in every room. To obtain NZ Building Code compliance, contact your local council.

Where is the best location to install a smoke alarm?

The best location for any smoke alarm is on the ceiling and in the centre of the room they are intended to protect. The alarm will operate normally if installed on a wall, however this can add minutes to the detection time, which are valuable in the event of a fire.

We recommend installing the alarm at least 30cm from the corner where the ceiling and wall join and 50cm from the apex of a cathedral ceiling.

Both of these areas are referred to as ‘Dead Air Zones’, with ‘Dead Air Zones’, oxygen will gather in these areas.

Which standard required for smoke alarms in New Zealand?

New Zealand accepts European Standard EN14604 and Australian Standard AS3786 certifications. Never install a smoke alarm without a smoke alarm certification.

Why should I choose to purchase a more expensive alarm versus the cheap alarms on the market?

The higher price of smoke alarms often reflects the quality of the components used and will often contain a longer battery life. The more level of quality, the higher the cost becomes. All CAVIUS alarms are 100% tested for sensitivity, sounds, power consumption and many other points. The manufacturing set up is audited by AFNOR and CNPP from France, one of the worlds best test institutes. Samples from all production batches are sent to an independent testing institute for additional testing – all to secure the worlds safest alarms for you.

When should I replace my smoke alarm?

All smoke alarms have a 10 year lifetime and expiry date. You will find the CAVIUS expiry date on the product label at the base of the alarm

My alarm does not sound when I press the test button?

Ensure the alarm is clicked firmly into the mounting base. The red activation button needs to pressed down entirely to power the alarm.

How often should I test my alarms?

We recommend that you do a visual check (the LED will flash every 48 seconds indicating the alarm is operational) every week. We also recommend pressing the test button on the alarm once per month.

What should I do if my smoke alarm beeps?

A short beep every 48 seconds may indicate the end of life of you battery. If the alarm is well before the 10 year life, the alarm may not quite be clicked into the base properly. Take the alarm out and re-click back into the base. You should hear and fell the click – similar to a seat belt.

How does my smoke alarm work?

CAVIUS smoke alarms are using photoelectric technology enclosed in what we call the ‘smoke chamber’. This smoke chamber contains a LED which will emit light on a photocell receiver. When smoke particles goes into the smoke chamber, it will reflect in the beam and will trigger the alarm.

What should I do if I’m having an alarm triggering?

Alert young children and seniors.
Leave the house following the escape route. Every second is important, do not loose time collecting valuable objects.
Stay close to the ground if the air is charged with smoke. Do not breathe completely and cover your mouth with a wet cloth if possible.
Once outside your house, call emergency services.

What is a smoke alarm?

Smoke alarm is an electronic fire security device which will early sense smoke to warn occupants with a loud siren so they can get out before being intoxicated by smoke. (80% of fire deaths are due to inhalation of toxic smoke)

Troubleshooting: Wireless Smoke Alarms

False Alarms:

  1. The alarm that has been activated will be the only alarm that flashes red (if you have the CAVIUS HUB and app, the app will notify you which alarm has been activated).
  2. Dust particles and insects can get in and live inside the chamber, when a draft comes the dust will cut out the optical light and create a false alarm. The alarm will need to be vacuumed as part of maintenance.
  3. The location may need to be changed. In areas where steam or high humidity gathers, this will sometimes trigger a false alarm.
  4. EMC Electromagnetic fields can interfere with the electronics of the smoke alarm. These fields are often formed around fluorescent lamps, “down lights”, transformers for light, fuse boxes, fan motors etc. – Always install the smoke alarm at least 100cm from this type of equipment. NOTE: EMC does not drain the battery.

The alarm won’t interconnect with the other Wireless Family alarms:

  1. Check first the alarm has been placed into ‘LEARN’ mode. The ‘LEARN’ mode switch can be found at the back of the alarm.
  2. Try reprogramming the entire family of alarms. This can be done by placing all the alarms into ‘LEARN’ mode and pressing down on one of the alarms – this becomes the ‘Master’. Any new codes generated and learnt by the alarms will override old codes.
  3. If you using the CAVIUS HUB and app, ensure the alarm is in ‘LEARN’ mode and the HUB has power and internet.
Troubleshooting: HUB

The HUB is connected to the internet with a cable through your home router. Your home router may be installed by your internet provider (ISP) or perhaps yourself. Things can happen, and some causes the internet connection to fail or become unstable. Below, you will find a guide from us to troubleshoot the most common scenarios we have experienced.

The HUB must be connected to an enabled LAN port on the router. Some internet routers have ports reserved for special usage, or have to be enabled to work. Consult your router manual to make sure, or try some of the other ports on the router.

Step 1: Does the HUB red LED light flicker?
– If it does, then the HUB cannot access the internet, and you should proceed with the next steps.

Step 2: Are you able to access the internet at all?
– Try with your mobile phone or computer using the wifi or with a cable (RJ45) from your computer through exactly the same port on your home router as was used by the HUB.

Step 3: Is it necessary to read the router manual? A home router typically has 1-4 LAN ports. The hub should be connected to one of those. If you use a WAN port, then it will not work, and if your home router has some ports reserved for TV or service then they will not work either. You may have to check the router manual, or simply try another port. Sometimes you have to login to your home router to enable more ports.

Step 4: Does it work at your neighbor?
– Before you proceed with more complicated steps, then it may be a good time to take the hub to another location and try it there. If it works somewhere else, then it may be worthwhile to proceed with the next steps.

Step 5: Do you have to restart or update your internet equipment?
– Home routers are built as specialized computers. They have memory, software, and lots of data to process. The hub will constantly try to communicate with it, and is therefore often the first messenger with bad news about your network. Your home router may even work for some of the Wifi connections, but not for others, due to overloads. And note that it is also ok to install your own router behind equipment delivered by your ISP (internet supplier) to get more LAN ports – the hub should still work fine and securely – but you will have one more thing to reboot and update.

Step 6: Did you block something in your router?
– Networks in offices are often controlled by
IT-departments, and sometimes makes use of advanced settings in the routers. Some of these settings may be in use on your home router if you have it from such a place. A factory reset or update may help.

Step 7: When it gets really advanced then you may need help!
– Typically you do not have to consider any of the advanced settings in your home router – all is handled by the hub, including secure communication. And if you do not know about such things, then it is probably better to buy a new and updated standard router for your home. That said, then in very special and rare cases you may want to look into the advanced settings in your network equipment. Is DHCP enabled? Are some MAC addresses blocked or filtered? Is UDP traffic enabled? Is UDP connections timeout above 40-60 seconds to avoid frequent fall outs?
