Hi,
Thanks for the responses. I didnt think that they needed to be fire doors but the stickers made me doubt myself. There are no detectors anywhere - primarily due to the fact that we have a 240V 3 wire manual system! (something else for the RA)
Edited to add: The inner room is a store room for stationary and the like. The outer room has a total of 4 inner rooms in it, one with an inner inner room. There is also an open wooden staircase that I have designates as not a fire exit. The whole area has access to 1 protected lobby leading to an ultimate final exit. There is another door but has a shutter on it so cannot be classed as a fire exit. It's beginning to baffle me!
In a situation where there are 2 adjacent offices, each with their own exit onto protected routes, those exits should be FDs, as should be the adjoining doors between the office but if one office exits through the other then it wouldnt need to be a FD. If that sounds corect, then I think I have grasped it....
Thanks for listening to my waffle.
