Smoke-Heat-Carbon detectors

[driverman]

Hi Guys, Spoke in earlier threads about S/H/Co detectors ect. Listen to opinions and comments and decided to go for the Acio equipment. However home owner went and got the Kiddie type. No doubt they will do the job but, As far I can see the fittings are designed to fit onto plaster cavity wall type fixings. I was hoping to seal holes up where cables come through ceiling and fit directly onto the joist. What you Guys think of the kiddie fittings. The way I'm looking at it with the Kiddie ones is the ceiling fire rating has been broken.

Realise it's probably too late but would this have solved your problem? (We've never used them)

that putty is horrible to use, takes ages to put on and it doesnt want to stick
