These optical smoke alarms only last 10 years or so. I bought this to replace existing one fitted by my builder. Delivery was fast and this just slotted in on the base plate of the previous one. Perfect

Have 3 of these in my house, installed when the house was built in 2011. One developed a fault and kept going off, As the three are linked via the mains when one goes off they all go off. Bought this to replace the faulty one. As it was exactly the same make and model I was able to leave the original base plate fitted to the ceiling and just replace the detector. Simple swap over, completed in a few minutes.

My alarm had become faulty so bought this one, i didn't use the base as had left the one there as it's fitted to the mains snd i have no clue. But just slotted this one in, came with a battery which was a plus.

This one was a replacement unit so fitted easily onto the existing base but I have upgraded to this one with a rechargaablle battery to save having to replace them after a few years. Very pleased.

Two of these were installed in my new build house 17 years ago. I’ve renewer them twice now - just have to swap the detector heads over without disturbing the bases & wiring. No problems. Easy to test & loud enough.
