Environmental sensing Advanced diagnostic technology

Once device data is downloaded, logged property temperature and humidity recordings from individual devices can be viewed via shareable reports, to ensure a golden thread of data and help identify properties at risk of developing damp and mould.

Battery powered protection 10 year battery included

The unit comes with a sealed, tamper proof battery that will last the lifetime of the alarm. The sensor within the alarm will deteriorate after 10 years, so to ensure protection from carbon monoxide, we recommend replacing the unit after this time.

10 year battery included
Sync-It™ (NFC Technology) Quick, quiet and contactless

With Sync‑It™ (NFC technology), information such as logged temperature and humidity readings, can be easily transferred from the device to a mobile phone through wireless communication.

The Social Housing Act is now law Discover more

The Social Housing (Regulation) Act 2023 is designed to protect tenants’ lives and compel landlords to address problems rapidly. The Act also includes Awaab's Law, providing more protection to residents in homes affected by damp and mould, with strict new time limits outlined for social landlords to investigate a reported problem.

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.
