The Alecto COA3920 cage detector provides reliable protection against carbon monoxide for up to 10 years. The alarm reacts quickly when the CO concentration gets too high, with a loud 85 dB sound and a light alarm. In addition, it also indicates prolonged low CO levels, which can be harmful to health.
The display shows carbon monoxide levels in ppm, battery status and notifications such as test status and error messages. The display allows you to easily monitor the situation at a glance.
The monitor meets the requirements of the European EN50291-1:2018 standard and features a test button to check the operation of the device on a regular basis.
The design of the COA3920 is unobtrusive and stylish. Its compact size (78 x 110 x 37 mm) makes it suitable for almost any space. The alarm can be mounted on the wall using the supplied base plate, screws and plugs, or placed on a flat surface.
