Assessment requirements

I asked elecsa about fittng isolation when smokes wired from regular used lighting circuit and they said a unswitched FCU as it got to be a means of seprate isolation but not by switching??????????????????????????????????????????????????//
building regs are a joke lol

That's my interpretation too, exactly as you would have isolation for an extract fan on the lighting circuit but unswitched as it's a safety item.

Would not a key switch also do.

Would not a key switch also do.

The type of decice isn't specified, the clause reads "there should be a means of isolating power to the smoke alarms without isolating the lighting".

Yes mate very ambigious
dedicated rcbo circuit
or regular used lighting with seperate means of isolation
manufacturer no means of switching off

300m from lights 300mm from walls not in bathroom
within 7.5 metres of every habitable room
not over a stair well or opening between floors etc etc
this is all well and good but what if the hall is the size of no more than 60cm x 90 and the only place you can put the hall smoke is over the bottom two steps
Elecsa say may be issue i said well were else can i put it as it will then either be to close to wall or light answer
Its down to you to decide as the installer etc nice so if i decide its the best place then it is
mate the smokes have given me more headaches than anything

when i asked elecsa ll he kept saying a means of isolation but no way of switching off no experience of key switches never used one was going to install one but decided to opt for unswitched fused spur ??????????????????????
see what he says on the day lol as it was them who said do this
