Cl 405.3
Detector spacing, wall distance and coverage
The detector spacing tool reads one row per detector type. Each row holds the spacing, the corridor spacing, the wall distance and the corridor wall distance. It holds the floor area per detector and the longest distance from any point to a detector, line or beam. Last is the limit below the apex of a sloping roof. A null wall distance means Clause 405.3 states none for that type.
