Question: If a ceiling has beams projecting more than 100 mm below the ceiling surface, how is smoke detector spacing affected perpendicular to the beams?
Answer options:
- No change required ✅ Reduced to 2/3 of normal spacing (6m) perpendicular to beams
- Reduced to 1/2 of normal spacing (4.5m)
- Detectors are not allowed on beams
Correct answer: Reduced to 2/3 of normal spacing (6m) perpendicular to beams
Explanation: For beams projecting more than 100mm, the spacing of smoke detectors must be reduced. Specifically, if beams exceed 10% of ceiling height, each 'pocket' requires detection. For shallower beams, spacing is reduced to 2/3 of standard spacing (9m * 0.66 = 6m).
