Brand Alecto The Alecto COA4010 carbon monoxide alarm offers reliable, long-term protection against carbon monoxide (CO) in your home. As soon as carbon monoxide is detected, the alarm warns immediately with sound, light, and a clear display notification. Equipped with a 10-year sensor and a powerful built-in lithium battery, this CO alarm guarantees continuous, maintenance-free safety for an entire decade.Thanks to its integrated display, you can easily read CO concentration levels, battery status, and other important notifications at a glance. Unlike many alarms with displays, the Alecto COA4010’s lithium battery ensures 10 years of optimal operation without replacements.The alarm not only warns of high CO concentrations (>50 ppm) but also alerts you when low levels (<20 ppm) are present, helping you act before health risks arise. When the concentration becomes dangerous, a loud 85 dB alarm ensures you are warned instantly — even while asleep.Installation is simple with the included mounting plate, screws, and plugs, but the COA4010 can also be placed freestanding on a flat surface. Compact and portable (40 × Ø110 mm), it’s also ideal to take with you on holiday.Details• Immediate CO detection with clear display, sound, and light alerts• 10-year sensor and lithium battery for long-lasting, maintenance-free protection• Warns at both high (>50 ppm) and low (<20 ppm) CO levels• Includes 10-year warranty – guaranteed reliability• Loud 85 dB alarm ensures you won’t miss any warning• Easy installation – mounting materials included• Compact design (40 × Ø110 mm), suitable for hanging or standing• Meets European standard EN50291-1:2018• Test button to check functionality• Battery end-of-life signal after 10 yearsPackage ContentsCarbon monoxide alarm COA4010 with built-in Lithium batteryBottom plateMounting material (2 screws and plugs)User Manual Product Dimensions Length 45 Width 120 Height 145 Weight 0.18 Kg
