Reduce the chance of being poisoned by carbon monoxide (CO). Our electronic audible CO alarms constantly monitor the home, providing early warning of the deadly gas well before danger levels are reached. Carbon monoxide alarms are simple to use and easy to install. They can also be taken on holiday. All our CO alarms are independently tested by either LPCB or BSI Kitemark and certified to the latest European standard BS EN 50291:2001. Additionally we have CO alarm solutions for the hearing and visually impaired in our Wi-Safe range.
