OK so not DIY but some here do find such info interesting.

I am doing an EICR on a block of 38 rented flats all owned by the same
company. One and two bed flats with just a single mains powered smoke
in the hallway (as per regs when they were built in 1994)

Out of the 16 I have tested 8 of them have either had the MCB to the
smokes turned off and the battery removed, the mains disconnected at
the smoke and the battery removed or the smoke heads have been removed.


I accept that the tenants have probably done some of this DIY
themselves to save buying a new battery.

However the most disturbing one is a flat that a tenant moved into 4
weeks ago. The mains had been disconnected from the smoke, taped up
and shoved into the ceiling as well as the battery having been
removed. Almost certainly like that when she moved in 4 weeks ago.

If they are linked burning toast in one flat will set them all off.



No. Not interlinked. These are mains powered smokes in the flats
internal hallway. One smoke per flat.

The communal hallways are a different matter. ie they DO have
interlinked mains powered smoke alarms. A pity that they all have low
voltage batteries and the smokes are above the new suspended ceiling
that was installed 12 months ago. All you can hear when you walk down
the corridor is the smokes bleeping.

I will soon be installing a new 60 detector 8 zone bi wire fire alarm
system for the communal hallways.
