Thanks for this. Seems crazy, as any other shaft penetrating sleeping compartment floors you would expect to see fully protected. I visited a large hotel the other day and the lift (non- firefighting) started at reception level and stopped on the sleeping corridors of all upper floors. Adjacent to all the bedrooms, no lobby protection. This is accepted?

Hi Tom, Sorry for the delay. So a standard passenger lift can go from protected sleeping corridor on one floor to another protected sleeping corridor on another floor. Surely a fire on on floor could now pass to another floor via the shaft? I thought lifts had to open into lobbies which would in effect created a protected shaft?

Hello, I understand that lifts should be in protected shafts. So in a four storey block of existing flats, there is a protected stair and the flats are accessed from a protected corridor. The lift is accessed from the protected corridor, adjacent flat entrances on all levels. I take it this is unacceptable or am I missing something? Thanks,

Basic question... Office corridor, MoE one end and at midway point, meaning there is a dead end of maybe 12 metres. Four or five offices along the dead end. The two remedies I understand however, do you extend the solution the full length of the corridor or just within the dead end area to the midway point MoE? So for example detection on all office along the full length of corridor or just offices in the dead end part of corridor? Thanks,

Hello, This may be a silly question... How can you tell the difference between Grade A (domestic) system and a L2 system? Thanks,

Hi all, OK so there is a protected stairwell in a modern school that has a small server room under the stairs. There is an air grill fitted which appears to be fire rated intumescent however, no dampers to prevent cold smoke transfer. Is this acceptable? Thanks

Hi all, OK so small block of flats, stay put policy, single stair, single exit. The exit door has recently been upgraded to a 'intercom' system. Residents leaving the building press a 'press to exit' button. The door fails safe if electricity goes down. No communal alarm system. My question is does this need a 'green box' manual override? Thanks,

Hi guys, I have a question regarding automatic detection in a small converted 'block of flats'. It's a two storey house converted to two flats, one flat ground and one flat 1st floor. Both flats accessed from small ground floor communal hallway. Communal hallway is ground floor only. So in 'Sleeping Accommodation' it says Grade D LD2 in communal areas for small premises however in LACORS it adds to that, interlinked heat detection in flat hallways. Obviously there is the question of how much control you have of a leashold flat for example. So the question is why the difference in the two guidance and am I missing something, what is the latest accepted standards? Thanks
