10 Year CO Alarm


A carbon monoxide alarm is an essential home safety device, working to prevent carbon monoxide poisoning in your home by monitoring and detecting the presence of carbon monoxide (CO) gas in the air.



The Danish-designed battery-operated CAVIUS CO Alarm is a welcome change from the large and unsightly CO Alarms we have become used to seeing. Utilising up-to-date technologies, this alarm provides early detection of carbon monoxide, warning with a loud piercing audio alert.

Based on our experience with photoelectric smoke alarms, CAVIUS is proud to have now created the world’s smallest CO alarm. With its 40mm micro design and ultra-long 10-year lifetime, this CO alarm looks amazing whilst ensuring that you are protected against the ‘Silent Killer’ that is carbon monoxide.

The CAVIUS CO alarm is made with the highest quality components, certified and compliant with EN50291-1:2018 and the CO alarm is also approved for Recreational Vehicles (RV) and can be used with the CAVIUS Build-In Base.
