Yes – The CO-9D Carbon Monoxide Alarm is suitable for all domestic settings, including caravan holiday homes, caravans, motor caravans – with the exception of boats.

A Carbon Monoxide alarm is the only way to receive an audible alert to the presence of Carbon Monoxide (CO) in your home, or whilst you’re away on holiday.

CO is a gas which cannot be seen, tasted or smelt but can result in CO poisoning and illness or in some cases death. It’s created in our homes when the fuel in products, such as boilers, fires and ovens does not burn completely. Regular servicing of these products can reduce the risk of CO being present but it cannot completely remove the risk.

The screen has two stand-by displays –

1. Room temperature and humidity levels are shown in degrees centigrade – making this alarm perfect for bedrooms

2. The current CO level in parts per million

To switch between the two displays you can press the test button – during this time the alarm will display the peak CO levels recorded by the alarm over the last 4 weeks.
