Mains Powered Smoke Alarms & Heat Alarms with Self-Charging 10 Year Back-up Battery - Firehawk RB Series
These Firehawk optical smoke and heat alarms are mains-powered and fitted with sealed self-charging back-up batteries designed to last their full 10 year lifespan without needing to be replaced. Suitable for Grade D1 installations and Scottish regulations, Firehawk FHN250RB optical smoke alarms and FHN450RB heat alarms can interlink in a system of up to 15 alarms to warn all occupants throughout the whole house if one detects a possible fire. The supplied Fast-Fix bases also allow for the easy replacement or swapping of smoke and heat alarm heads from the same range if required. An "end of life" warning chirp will sound when the whole unit needs replacing after 10 years, but this can be silenced for 10 hours in case it starts during the night.

Work well and look neat & tidy
Used the Firehawks to replace my old mains BRK alarms and whilst the new ones work well and look good (as far as alarms do) the fixings are different but with a bit of juggling I managed to fit them on the old base and wire them into it so I didn't have to remove the old base plates to leave gaps in the paintwork or re-do the wiring from scratch. It would be a good area for standardisation if manufacturers could agree on a common baseplate and connector for mains alarms it would make life easier.
