MAB Posted March 2, 2021 Share Posted March 2, 2021 A friends daughter has just bought a newish flat and has sent a photo asking what these are? Apparently there is one of these in each room near to the ceiling in the middle of the wall? Thanks in advance.... Link to comment Share on other sites More sharing options...
markc Posted March 2, 2021 Share Posted March 2, 2021 No idea what the blocks are, but i am curious why there is what looks like skirting on the ceiling 1 Link to comment Share on other sites More sharing options...

Nickfromwales Posted March 2, 2021 Share Posted March 2, 2021 Looks like the type of junction boxes associated with a burglar alarm. Maybe where PIR's have been removed because previous occupants had pets etc. Is there an alarm there now? 1 1 Link to comment Share on other sites More sharing options...
Bitpipe Posted March 2, 2021 Share Posted March 2, 2021 My instinct would be to remove that screw and see what's inside... 1 Link to comment Share on other sites More sharing options...

MAB Posted March 2, 2021 Author Share Posted March 2, 2021 (edited) Thanks for your thoughts, I will pass on and report back. I think due to covid restrictions no 'more technically' minded family member has been able to visit to investigate further and removing a screw to investigate (which is what I would do) is not something non-technical safety minded people do if they think something is electrical. Looked like a skirting board to me too but I will check if it is on the ceiling! Edited March 2, 2021 by MAB 1 Link to comment Share on other sites More sharing options...
dpmiller Posted March 2, 2021 Share Posted March 2, 2021 and if it is alarm, they tend to have an anti-tamper switch inside.. 1 Link to comment Share on other sites More sharing options...
Onoff Posted March 2, 2021 Share Posted March 2, 2021 Probably like the switch in that episode of Friends... 1 Link to comment Share on other sites More sharing options...

TonyT Posted March 2, 2021 Share Posted March 2, 2021 And if it is a functional alarm, and properly installed, removing the screw will open the tamper contact and will result in alarm going off even if the alarm isn’t set. you may need engineer code to carry out a reset, user code nit having the appropriate permission to do so. 1 Link to comment Share on other sites More sharing options...
