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.
Yes – Our FP1820W2-R, FA33820X4 and FA3322X4 products have sealed for life batteries and will protect your home, without you need to replace the batteries every year.
Carbon Monoxide is produced when fuels burn incompletely – this could be from a boiler, gas fire, oven, log burner or a blocked flue or chimney. It can also travel through walls from adjoining properties, so as well as having an alarm next to appliances in your property we would also advise you have one in living spaces and bedrooms.
To help prevent a Carbon Monoxide leak we advise getting your appliances regularly serviced by reputable engineers who are gas safety registered.
When a Carbon Monoxide alarm is triggered, it will emit an alarm sound consisting of 4 loud beeps and a break repeated until the sensor is clear of Carbon Monoxide gas.
Yes – the FireAngel Pro Connected FP1820W2-R Carbon Monoxide Alarm, when paired with a Smart Gateway, will allow you to review alerts and easily test the alarm from your phone.
The common sources of Carbon Monoxide (CO) are cookers, fires, boilers, oil and gas boilers, portable generators, oil or solid fuel cookers, gas or paraffin heaters, barbecues (BBQs), clogged chimneys, wood or gas fireplaces, cigarette smoke or any fossil fuel-burning appliances.
Regular servicing of these items will help reduce the risk of CO in your home but it will not completely remove the risk. The only way to detect CO in your home is to install a Carbon Monoxide detector with an audible alarm.
Yes – this carbon monoxide alarm is suitable for all domestic settings, including caravan holiday homes, caravans, motor caravans and boats.
From October 1st 2022, the law is changing surrounding carbon monoxide alarms in rented properties – for both the private and social sectors.
Your landlord will need to ensure as a tenant you have a working carbon monoxide alarm 1-3 metres away from any fuel burning appliances in a room (excluding gas cookers) and that any faults or repairs are carried out on the alarm in a timely manner. For more information, read this blog.
