Hi, appreciate this is more fire regs than wiring regs but hopefully someone can help clarify.
There will be doors separating a corridor in an apartment building, that will be held open by détentes.
Full smoke detection coverage to Cat L4 will be provided using smoke detectors with a coverage radius of 7.5m.
Does BS5839-1 require a smoke detector to be within a specific distance of the held open door, on either side? Or is the 7.5m rule ok?
I know BS5839-1 states a max distance of 1.5m from a stairwell door, however the above scenario are simply doors to separate long corridor sections.
Thanks
