Figure 5.2: Connecting a D306 Remote Indicator Plate
You can wire the D306 a maximum of 500 ft (152 m) from the receiver.
A D307 Remote Test and Indicator Plate can be used in place of the D306 and should be
connected if remote alarm testing is desired. To connect a D307, follow the instructions in the
D307 Installation Instructions.

Wiring multiple detectors

For smooth, flat ceilings, mount the detectors so there is spacing of no more than 60 ft
(18.3 m) between beam paths (with no more than half of this spacing between the beam path
and side wall, the wall parallel to the beam path). Other spacings depend 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 the detectors a minimum of 30 ft (9.1 m) apart. For
layout placement, see the following figure.
