NZ Building Code New Requirements
From November 2023 the Building Code Acceptable Solutions for Protection from Fire (C/AS1 and C/AS2) will be amended to make interconnected smoke alarms the minimum fire safety system for new built homes and substantial renovations, citing NZS 4514:2021 – Interconnected smoke alarms for Houses.
- All smoke alarms must be either powered by a long-life (minimum 10 years, non-removal and sealed) battery or mains power.
- All smoke alarms must be interconnected with each other, this can either be wired or wireless. The CAVIUS Wireless Family alarms connect with each other wirelessly, without the need to run cable between each alarm. Interconnecting the CAVIUS Wireless Family alarms is a simple and quick process.
- A smoke alarm must be installed in every bedroom, living spaces, hallways, and landings within the dwelling. On a multi-level household unit, there must be at least one smoke alarm on each level. If the kitchen is separated from the living spaces and hallways by doors that can be closed, a heat alarm shall be installed. This may include the scullery.

The Cavius Advantage
Welcome to CAVIUS. Since 2004 CAVIUS has inspired the world of alarms, proudly protected homes, and saved lives. The unique, Danish design, combined with a professional UK-based Research & Development team, brings you the most advanced alarms. Why choose CAVIUS? Because the alarms are superior to other standard designs for more than one reason:
CORE TECHNOLOGY
The world’s smallest smoke and heat alarms were designed by a Danish team, who are experienced in developing smoke alarm systems to EN54-7 certification.
DESIGN
The CAVIUS alarms use premium components to ensure reliability in performance, stability, and the alarm will be 100% operational during their lifetime of 10 years.
CHAMBER SIZE
To maintain a high quality performance; CAVIUS invests additional costs in the manufacturing of optical components, amplifiers for the photodiode and a micro controller to carry out signal processing.
PERFORMANCE
The performance of the smoke sensor includes a wide smoke entry in all orientations around the alarm. It also includes strong resistance to false alarms due to point sources of contamination, insects, and humidity. CAVIUS smoke alarms are certified for recreational vehicles.
SOFTWARE
The software in the CAVIUS smoke alarm includes a fire detection algorithm with features similar to that found in expensive analogue detection systems. The software also includes a calibration routine, which stores a gain factor in flash memory. This is more accurate than the variable resistor set by hand on most other alarms, and much more reliable long term. The software also includes features for self-test, hush mode after alarm, and battery test.
MANUFACTURING
During the manufacturing stage, 100% of all CAVIUS alarms are tested in a smoke tunnel to ensure the right calibration and are checked in an echoic room for sound output test. Samples from each production week are sent to an accredited lab and an external audit company will inspect and test the alarms before shipping them to the retailer. Our factory is audited several times per year from NF, VdS, and ISO.
