About this product
The Kidde KID7DCOC continuously monitors for the presence of deadly carbon monoxide (CO) in the home providing a constant protection against its effects. As well as twin red and green LEDs, the 7DCO features a digital display that continuously displays CO levels detected. The alarm can either be installed on a wall or just placed on a tabletop or shelf for added convenience. It is also ideal for use when on holiday, in rented accommodation, or for use in caravans and boats and complies with the very latest EN50291.2010 standards, Parts 1 & 2 (boats and caravans). The Kidde K7DCO Carbon Monoxide Alarm features an industry leading 10 year sensor life, meaning it lasts 40% longer than any other CO alarm. The alarm has an end of life warning to replace the unit after ten year's protection.
