StrongArm Installation and Reference 40
Standard 11 Pin Box Type Vehicle Detector Installation
1. If standard 11 pin vehicle detectors are to be used, snap up to three sockets onto the aluminum
DIN mounting rail, with the key in the center hole facing to the left. Mount on the shelf near the
top of the operator and wire as shown below.
2. Both 24 Volts AC or DC are available, so either detector voltage may be used. (24 VAC is not
available if the operator is a battery type) 24 VAC is available at the spade terminals on the lower
left corner of our power supply (marked ACC). 24 VDC is available from the Common Buss and
the +24 V spade terminals next to the common Buss.
3. Connect 24 Volt power to the detector. Polarity does not matter if the detector is a 24 AC model.
If a DC detector is used, pin #1 is (+) on a DC detector and pin #2 is ( - ).
4. Connect the output pin #6 to the common Buss on the power supply and the output pin #5 to one
of the four detector inputs (depending upon the detector function required) on the Smart Touch
Controller terminal strip.
5. If multiple detectors are used, join the wires from socket to socket rather than run each to the
same location separately. The only wires that are separate is the output wire to the Smart Touch
Controller and the loop input wires.
6. Always keep the loop wires well twisted at all places beyond the area of the loop. The lead in
portion sealed in a saw cut does not need to be twisted so long as the wires are encapsulated in
loop sealant and cannot move.
