BI-PARTING GATE SETUP
Earth Ground
Place the WARNING
WARNING
signs on both sides of the gate.
Take a photograph of the
complete installation site.
In-ground vehicle loop detectors
Bi-parting gate setup:
1. Install the primary and secondary operators.
2. Set up external entrapment sensors on both
operators. Vehicle detectors may be installed in either
operator. Make these connections before you connect
the operators.
3. Test cycle the operators independently to make sure
there are no problems with gate travel and open/close
limits.
4. Install a twisted shielded 2 pair wire harness between
the two operators. Match A-A, B-B, and COM-
COM. Install the grounding shield on only one of the
controller mounting brackets.

5. Set one operator as the primary and the other as the
secondary.
6. Test the gate operation.
7. Adjust LEAF DELAY CLOSE and LEAF DELAY
OPEN if required.

Wind Load Factors
Design gate panels to
minimize wind loads.
Keypad or Card Reader
Mount access control devices
at least 6 ft (1.8 m) beyond gate.
Edge Sensor
Sequenced gate wiring:
Sequenced gate wiring is similar to dual gate wiring.
Instead of the DUAL GATE terminal, use the SEQ GATE
terminal. Install a twisted shielded 2 pair wire harness
between the two operators. Match A-A, B-B, and COM-
COM. Install the grounding shield on only one of the
controller mounting brackets. Figure 41. Refer to page
46 and page 47 for loop view diagrams.
When sequenced gates are being used in barrier arm and
security gate system, both operators must be set to the
same loop view setting. When sequenced gates is used
for a Sally Port system, then one gate must be set to Sally
A and the other must be set to Sally B.
