5.3 Wiring multiple detectors
For smooth, flat ceilings, mount the detectors so the spacing is ≤ 60ft. (18.3m) between
beam paths. Ensure that no more than half of this spacing is between the beam path and side
wall. (The side wall is the wall parallel to the beam path). Other spacing depends on ceiling
height, air flow characteristics, and response requirements. The minimum spacing between
alternated adjacent detectors is 1/10th the distance between the transmitter and receiver. For
example, if the beam length is 300ft. (91m), place detectors ≤ 30ft. (9.1m) apart. For layout
placement, see the following figure.
