Carbon monoxide (CO) is a poisonous gas that can build up indoors and you have no way to detect it until you start to feel ill. Appliances like water heating systems, cookers, boilers, and open fires can release carbon monoxide.

Installing carbon monoxide detectors is a crucial way to protect you and your loved ones from CO gas poisoning whether you are sleeping or awake. In this case, the CO builds up and the detector will alert both the resident and the central station.

These ones have advantages over the classic smoke alarms, some of them detect not only smoke but also changes in temperature to detect a fire before the smoke occurs, you can regulate the sensitivity to avoid false alarms and you can control it remotely through your smartphone.
