Sleep Easy
With our sleep easy function, users can silence battery alerts for 8 hours, providing vital time to replace an alarm and reduce nuisance noise.
Intelligent CO sensing technology enables the alarm's high sensitivity mode to be activated, if it predicts CO levels will increase to or above 180ppm for a quicker alert.

The unit comes with a sealed, tamper proof battery that will last the lifetime of the alarm. The sensor within the unit will deteriorate after 10 years, so to ensure you're protected, we recommend you replace the unit after this time.

Residents have convenience of the quiet self-test function for regular, discreet testing at a reduced noise level.

FAQ's
A Carbon Monoxide (CO) alarm is the only way to alert residents to the presence of Carbon Monoxide within a property. A CO alarm via an audible alert
CO also known as ‘the silent killer’ is a gas which cannot be seen, tasted or smelt but can result in CO poisoning and illness or in some cases death. CO forms 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.
Our FireAngel Carbon Monoxide (CO) detectors are designed so that alarms can be wall-mounted or left freestanding within a property. Ideally, a CO alarm should be installed in every room with a fuel-burning appliance e.g gas hob, open fire, boiler. Additional alarms may be installed to provide adequate warning for occupants in other rooms, by placing alarms in rooms in which they spend considerable time whilst awake e.g living rooms, bedrooms, kitchens.
Boiler Room | Bedroom | Kitchen | Living Room
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.
Using a gas safe engineer to regularly service these items will help reduce the risk of CO in a 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. Gas safe engineers can be found via the ‘Gas Safe Register’ – this is an official list of businesses that are legally permitted to carry out gas work.
