The Firehawk carbon monoxide alarm CO7B is certified for domestic and travel uses. Portable, compact and light, it's easy to wall-mount in any home, hotel or office, or used as a free-standing carbon monoxide detector in caravans, campervans, boats and while camping. Carbon monoxide alarms are a requirement throughout the UK in rooms containing solid fuel-burning appliances, like open fires and stoves. However, gas devices are also a source of carbon monoxide leaks, so it's recommended to install sensors and alarms in every room containing such appliances and devices, like boilers, heaters, cookers, barbecues and others. With a sealed 7-year battery, the Firehawk CO7B will ensure your carbon monoxide safety in and outside your home for a very long time.
