Brand  Alecto 

The Alecto COA3910 carbon monoxide alarm ensures reliable protection for you and your family by immediately warning you when dangerous levels of carbon monoxide (CO) are detected. Equipped with a long-lasting 10-year sensor, this CO alarm offers continuous safety and peace of mind.

The COA3910 has a modern, discreet design with a stucco-textured housing that blends seamlessly into any interior. It’s compact and lightweight, suitable for both wall mounting and freestanding use. Installation is quick and easy thanks to the included mounting plate, screws, and plugs, and the alarm is ready to use immediately with the three included AA batteries.

Unlike standard CO detectors, the Alecto COA3910 also warns at low CO concentrations, helping you take action before the situation becomes dangerous. The clear display shows the current CO concentration (in ppm), battery status, and alerts you to errors or end-of-life notifications.

If a high CO concentration is detected, the device emits a loud alarm (>85 dB) combined with visual LED signals, ensuring you’re alerted even while asleep.
