Sorry guys, lack of accurate terminiology on my part - the builders didnt install it, it was indeed done by a proper installer - but having done the assessment myself - I can't find a justification for it?
Given that, if someone has Eastenders on nice and loud in their abode, no ones going to hear it in the flats. If they do hear it and there is (by some miracle) a problem in the lobby or stairs, then aren't we potentially sending them out into a smoky (or jolly hot!) corridor when they'd be better off inside continuing to watch Eastenders blissfully unaware.
I thought nice new buildings built in accordance with building regs didnt need them in these circs? There is no particular fire hazard in the corridors, a small amount of post on a table sometimes, and entry is secure.
Any thoughts before I make an ass of myself and get it decommissioned? I'm assuming someone put it there for a reason - just can't figure out what that reason should be?
