Suitable for kitchens, garages, and other areas prone to dusty and humid environments to reduce false alarms, they should be installed in the home alongside a combination of smoke alarms with at least one alarm on each floor.

When temperatures soar to 58°C and above, the 85-decibel alarm will activate and warn you of the potential hazard. Featuring a sealed lithium battery which can last for 10 years, the alarm benefits from a 30-day low battery warning. With a red LED indicator to show the alarm condition, you can test the operation of the alarm using the test button.

Easy to install using the two screws and wallplugs included, the Cavius alarm is 100% tested and has EN 60065:2002 approval. Plus, how many other alarms do you know which have won a design award?
