Hi @UNG
I beleive it does at some point mate but in terms of following that cable to see if get there eventually I couldn't tell you as it disappears through walls and ceiling quite a bit. I will have a look on the other side of the door tomorrow as I think initially it goes into some white box that is do do with the fire alarms.


Thanks for your post ?

Looking at the way the FP is connected I suspect the "white box" it goes to is a a relay interface that disconnects the door power when the fire alarm is activated
