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.
