Carbon monoxide alarm with 10-year sensor run time and display

The Alecto COA3910 carbon monoxide alarm provides reliable protection for you and your family by alerting you immediately when dangerous levels of carbon monoxide (CO) are detected. Equipped with a durable sensor that lasts for 10 years, this CO alarm provides 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 is 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 immediately ready for use with the three AA batteries provided. Unlike standard CO detectors, the Alecto COA3910 also alerts at low CO concentrations, so you can take action before the situation becomes dangerous. The clear display shows the current CO concentration (in ppm), battery status and alerts you in case of errors or messages indicating end of life. If a high CO concentration is detected, the device emits a loud alarm (>85 dB) combined with visual LED signals, alerting you even in your sleep.
