FireAngel One: Make protecting your home feel effortless
© Copyright 2026 Fireangel Safety Technology

The smart solution that
grows with you

FireAngel One is designed to make protecting your home feel effortless. A unified, connected system that can grow with your needs, helping to keep you and the people you love safer.

Safer when you're interlinked

An interlinked system like FireAngel One offers a higher level of protection: when one alarm alerts, they all do.

Bluetooth® interlinking can give you and your loved ones valuable extra time to escape compared with standalone alarms, alerting you to danger in one part of your home while you’re elsewhere. For example, an alarm in the kitchen can alert you while you’re asleep upstairs.

Know which alarm has activated through the app, helping you identify where the danger may be and respond quickly to a fire or carbon monoxide event.

Sustainability

Protecting your home shouldn’t come at an unnecessary cost to the environment.

The outer casing of our smoke, heat and combi alarms is made with up to 65% recycled plastic that may otherwise have ended up in landfill, oceans or waterways. Our packaging is recyclable and made from cardboard and paper wherever possible.

Sealed 10-year batteries are designed to last for the lifetime of the sensor, reducing the need for battery changes and helping to minimise waste.

Our carbon monoxide alarms comply with the relevant British Standards and certifications, which means recycled plastic cannot currently be used in their construction. We’re committed to finding new, more sustainable ways to protect lives, including longer-life batteries and future-ready technology designed to reduce the need for replacement components throughout an alarm’s lifetime.

Caring for the ones you love

The people who once cared for us can sometimes need a little more support as they get older.

FireAngel One can help you feel more connected to your own home’s protection and provide reassurance that loved ones are protected too. Using the Angel Connected app, you can stay informed about your connected alarm network and receive notifications when attention may be needed.

Caring for the ones you love

Protect your investment

You’ve got your new home, and now you can’t wait to make it yours. As you choose the perfect paint, furniture and finishing touches, make safety part of the plan with FireAngel One.

An interlinked, sealed-battery system means that when one alarm alerts, they all do. Know about potential danger in a room you’re not in, helping to give you more time to react and protect what matters most.

Protect your investment

Away from home?

FireAngel One can connect to a gateway via Bluetooth®, extending your connected protection beyond the walls of your home.

Whether you’re travelling for work, away on holiday or simply out for the day, the Angel Connected app can help keep you informed of alerts and faults, wherever you are.
