Photoelectric Smoke Alarm (Wireless Family)


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 thousands of pounds buying or designing and building your dream home and then, reluctantly, install large and unsightly smoke alarms throughout – well, not any more!


Wireless Family Photoelectric Smoke Alarm

The CAVIUS Wireless Alarm Family is the latest addition to the CAVIUS range. Using innovative Radio Frequency technology, our Wireless Family alarms connect with each another offering extra protection for your home and family.

The CAVIUS Wireless Photoelectric Smoke Alarm has been designed to warn you of fires and should be installed in all the main areas of the home, these areas include the bedrooms, lounge, and hallway. For other areas where a smoke alarm cannot be installed and a flaming or flash fire is likely to occur (such as the kitchen, garage, workshop, or laundry) a Wireless Family Thermal Heat Alarm is recommended.

Smoke alarms are an essential item to have in the home as they act as an extra layer of protection, especially at night when people are asleep. The earlier you can detect smoke or fire in your home, the higher the likelihood of saving your home and more importantly, your life. Just like you would wear a safety belt as a precaution – it always pays to put safety first and be prepared for an unexpected emergency.

The Wireless Family Photoelectric Smoke 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. Earliest detection provides vital minutes and will help with evacuation out of the house faster in the case of a fire.

The CAVIUS Wireless Photoelectric Smoke 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.

The range of the alarms depend on the building materials and should be tested in each individual case. During our product testing of the Wireless Family, the alarms connected at a minimum of 100m in an open field and have been set up and tested successfully in a standard two level, four-bedroom home.

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 family Photoelectric Smoke Alarm also syncs with the Wireless family Thermal Heat Alarm.

CAVIUS devices have a 30 day low battery warning, increasing your chances of identifying that your battery and 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.

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 Wireless Family alarms suit any new home, refurbishment and areas of your home like the bedroom, lounge and hallway. With a 5 Year long-life battery included, there is a lot to love about such an innovative alarm.
