Awkward fitting because of plug size. I already had two smoke detectors fitted 20 years ago of the same manufacturer. The new ones didn't come with a back plate and so I had to adapt the existing one's to fit the new alarms. This was because the plug in on the new ones was considerably larger than the old ones, which made them difficult to fit.

Does the job The only demerit is that their white and my ceiling's white are very different whites. One oddity: The test button only tests this individual alarm's siren, not the others in the circuit. The others test the entire system. Thus it makes you wonder of there is a misconnection
