Hi i am after some advice. An old victorian 4 storey, ground and 3 floors block of flats with a large central staircase is fitted with old doors, which open onto a very short corridor leading to the staircase, some glazed, some with non FR fanlights. Each flat is individually owned and not all have smoke detection. Some front doors could be considered notional fire doors. The flats are split into 2 wings and all have a 2nd fire escape with call points an alarm and smoke detection accessed from the back of each flat. Would the flats still.need to upgrade front doors to provide FR or if all flats installed smoke alarms would the secondary escape mitigate the lack of FR to the entrance doors?
