Safer by 10 years in development

CAVIUS doesn’t just make smoke alarms. We’ve been constantly refining and testing the world’s most advanced alarms since 2004, relentlessly pursuing better, safer alarms. Created by Danish designers and British engineers, all CAVIUS alarms are meticulously assembled by hand.

A little genius. The world's smallest smoke detector.

By looking a little closer at smoke alarm technology, challenging the science and refining every possible detail in its design and manufacture, we created the world’s smallest alarms. Our Nano range of alarms are barely visible – even right in the centre of the room (which is exactly where a smoke alarm is most effective).

Small but very effective

In our pursuit of a smaller smoke alarm, we had to be a little better at everything. The result is not just a minimalist alarm, but a safer one.

Introducing CORE Technology

CAVIUS has spent 10 years refining the science within our smoke alarms. CORE Technology is the first in the world to stack the components, within a perfectly proportioned chamber, to create a significantly smaller smoke alarm with much more precise signal processing.

OPTIMAL CHAMBER SIZE

Thanks to our world-leading CORE technology, the chamber in our photoelectric smoke alarms is the optimum size for early detection of smoke and fewer false alarms

BESPOKE SOFTWARE

The software in the CAVIUS smoke alarm includes a fire detection algorithm with features similar to that found in expensive analogue detection systems

CUSTOM COMPONENTS

CAVIUS alarms use only the highest quality components to ensure quality, reliability, stability and to ensure products are 100% operational during their lifetime.

INCREASED ACCURACY

CAVIUS alarms have two levels of mesh screening to minimise insect and dust contamination and additional humidity protection – alleviating the potential for nuisance alarms.
