3.3.1 Emitter and Receiver Hookups
Emitters and receivers connect together in parallel to terminals #4 through #8 of the
control module (identical for both control module models). See Figures 3-3 and
3-4 for wire color information.
3.3.2 Inputs
System Power: Connect a source of 16 to 30V dc, rated at 1 amp or greater, to control
module terminals #1 (+) and #2 (-). Connect a good earth ground to terminal #3 to
provide electrical and RF noise immunity to the System.
NOTE: Remove power before making other connections to the controller.
Gate Signal: Connect a switched source of 10 to 30V dc to terminals #11(+) and
#12(-) to provide a gating input (if required). The gating voltage typically is switched
by the open-collector output transistor of a dc sensing device. The gate signal controls
scanning when the Gate option is selected (see Section 4.4).
3.3.3 Outputs
Each control module has two solid-state discrete outputs, labeled Output #1 and
Alarm. Both are rated at 30V dc max., 150 mA max. They are either both NPN or both

NOTE: The “drain wire” is the uninsulated
stranded wire which runs between the
braided shield and the foil shield. The foil
shield and the braided shield should be
removed at the point where the wires exit
the cable.
