Our mains-powered optical smoke alarm has a compact design, a rechargeable backup battery and is quick and easy to install too, which is why it’s recommended and installed by fire and rescue services across the UK. Interlinkable to up to 14 other Firehawk smoke and heat alarms, this ensures the whole home is aware of a potential fire wherever they are.

Mains-Powered, Interconnected Smoke Alarm

The Fast-Fix base simplifies fixing and wiring, connecting to the 230V power supply and interlinking cable, the alarm unit can then easily be installed later. Should you have a power cut, the 10-year backup battery will kick in to ensure you’re still protected which then recharges when the power is back up for next time.

Suitable for bedrooms, living rooms, hallways, and landings, the optical smoke alarm features Thermal Stability Enhancement technology to reduce nuisance alarms whilst enhancing the detection of smoke for early warning. Plus, the unique insect screen keeps troublesome spiders out, benefits from an extra-large test and silence button for simple operation and has an 85 Decibel alarm that’s hard to ignore too.

CE Marked and approved to EN14604:2005, the Firehawk mains-powered optical smoke alarm is suitable for installations complying with BS 5839-6 Grade D1 and 2022 Scottish Fire Safety Legislation. This is best installed alongside the Mains-Powered Heat Alarm in your kitchen.

Please Note: This new version is currently not compatible with older FH250RB smoke alarm models, or the previous FH450RB heat alarm.
