Warns when dangerous CO levels are detected

How does it work?

CO is a potentially lethal gas emitted from faulty appliances such as boilers, cookers or fires. It has no taste, smell or colour so it is very difficult for individuals to detect a problem. The Tunstall Carbon Monoxide Alarm links to a Lifeline home unit, or Tunstall telecare enabled system, to provide an accurate and reliable warning if dangerous CO levels are detected within the home.

The Tunstall Carbon Monoxide Alarm provides an immediate alert when dangerous CO emissions have been detected due to a blocked flue or 


fault in a fuel burning appliance, raising an alarm call to a scheme manager or monitoring centre. The alarm will provide repeated detection without needing to be replaced and has a sealed battery with a seven year life. The memory function records the last CO alarm level, and the alarm also features a Test/Hush button. The alarm is officially approved and kitemarked to the European standard for domestic Carbon Monoxide alarms, EN 50291.
