Why choose a 10-year battery alarm?

A sealed 10-year battery means there’s nothing to forget, replace, or maintain. The alarm is operational from the day it’s installed until the day it needs to be replaced — typically at the 10-year mark. CAVIUS alarms also perform an annual chamber sensitivity calibration to ensure detection accuracy is maintained throughout the alarm’s lifetime.

How do I interconnect battery operated alarms?

All CAVIUS battery alarms use built-in RF technology to communicate with each other. To link a new alarm into an existing system, simply activate the Link mode on the alarm — the process takes less than a minute and requires no tools, apps, or internet connection. Once linked, activating any one alarm in the system will trigger all others to sound.

Frequently asked questions

Can I replace the battery in a 10-year alarm?
No. The lithium battery in CAVIUS battery operated alarms is sealed and non-removable. This is intentional — it ensures the alarm remains operational for its full lifespan and removes the risk of the battery being removed and not replaced. At the end of the 10-year life, the whole unit should be replaced.
The CAVIUS Wireless Family supports multiple alarms across a property. The effective range will vary depending on building materials such as concrete floors, brick walls, or dense framing. We recommend testing the connection during installation and contacting our support team if you have concerns about range.
Yes. CAVIUS battery operated wireless smoke alarms are AS3786:2014 certified and compliant with NZS 4514:2021, which is referenced by the updated NZ Building Code (November 2024). They are suitable for new builds and consented renovations.
Yes. CAVIUS battery operated and mains-powered alarms are both part of the Wireless Family range and can be interconnected in the same system. This is a common setup in new builds where most alarms are battery-operated but a mains-powered option is specified in certain locations.
