In corridors less than 2m wide the horizontal spacing of detectors may be
increased, the areas of coverage need not overlap as in the case of a room. Any
corridor over 2m wide is deemed a room and device spacing should follow the
standard for rooms (see page 5).
Detectors must not be sited less than 1m from air inlets or air conditioning units.
A device should not be mounted within 500mm of any obstruction. If the top
of a solid partition is less than 300mm from the ceiling then treat it as a wall.
Similarly, ceiling obstructions such as beams should be treated as walls if deeper
than 10% of the ceiling height.
