Plug in connector needs upgrading otherwise good.
Installed three of these to replace BRK’s which are no longer sold in UK. Seems fine other than the power connector between base plate and main unit. The spade connectors are very small and pushed out of the plastic plug when pushed home on two of the three units. Needs beefing up.

Excellent Replacement for our old Smoke Alarms
Easy to replace our existing smoke alarms with the Kidde KF20 as they use the same base fittings. Just wish the company reinforced the fact they should be replaced every 10 years!! Our old ones had been installed when the house was built 21 years ago and the manufacturer has now marked the devices to state they should be replaced in 2034!!
