CONNECTING STANDARD 11-PIN BOX TYPE VEHICLE DETECTORS
Connecting Standard 11-Pin Box Type Vehicle Detectors
If photo eyes are used to monitor
vehicle traffic instead of loop detectors,
connect the photo eyes using the same
steps. See “Installing Photoelectric
Sensors for External Entrapment
Protection Only” on page 145 .
If there is any detector fault, the gate
operator functions as if the detector
is triggered. Carefully consider
your peripheral connections. Any
peripheral device required for safe
gate operation should be attached
24VDC in case of an AC power
outage. Additionally, box detectors
with relays require five times more
power than HY5B detectors. UPS
battery life will be extended if
you use HY5B detectors instead.
If standard 11-pin box type vehicle detectors are to be used, perform the following procedure.
1� If there is sufficient space, install the sockets in the control box; if not, then install them in a separate
external housing. Figure 31 is for general reference only.
2� Connect 24 Volt power to the detector. Connect Pin No. 1 to a 24VAC or 24VDC terminal and Pin No.
2 to common. (You must provide your own power supply if 24VAC is required.)
3� Connect output Pin No. 6 to the Common Bus and output Pin No. 5 to one of the four detector
terminal inputs (depending upon the detector function required) on the SmartDC Controller.
4� Repeat Steps 1 through 3 for each HY5B detector.
5� If multiple detectors are used, route the power wires and common wire from socket to socket (daisy
chaining) rather than individually running each wire to the same location. See Figure 31. The only
wires that are separate are the output wire to the SmartDC Controller and the detector loop input
wires .
