Dual Gate Installations
Two operators can be used in dual gate installations. The operators
communicate with each other through the 3-wire COMM LINK terminals.
When one operator activates, the COMM LINK connection signals
the other operator to activate. Each operator functions independently,
controlling its gate and monitoring its inputs and accessories.
A three-wire shielded conductor cable is required to connect two
operators together for dual operation. Use Belden 8760 Twisted Pair
Shielded Cable (or equivalent) only – P/N 2500-1982, per foot).
✓ NOTE: The shield wire should be connected COMM LINK terminal
“C” in both operators.
Three of the programming functions available are only used for dual gate
installations:
• Dual Gate Enable
Dual Gate Enable must be set for all dual gate installations.
• Stagger Mode (Typically not used with barrier gates)
The Stagger Mode function determines if the operator has a
delayed open or a delayed close. In dual swing gate installations,
typically one operator is programmed for delayed open, and the
other operator is programmed for delayed close.
• Stagger Delay Time (Typically not used with barrier gates)
The Stagger Time sets the length of the delay for the Stagger Mode.
See Pages 11 & 13 for details on these three dual gate programming
functions.
Set the following parameters in each gate operator individually in a single gate
mode before connecting the network cable and operating in dual gate mode.
1. Open and Close Limit settings
2. Open and Closed direction inherent
entrapment protection (OC & CC)
After these parameters have been set, and each operator has been
tested independently and is functioning correctly in single gate mode,
then set BOTH operators to dual gate (dg) in the Paired Mode setup step
under Basic Programming steps.
Gate Operation
Open Button
Opens the gate. If the Auto Close Timer is set, it will be suspended until
the OPEN button is released.
Close Button
Closes the gate if the gate is open. Also closes the gate if the gate is in
the process of opening.
Stop Button
Stops the gate from opening or closing at any time.
Single Input
Opens the gate if it’s closed and closes the gate if it’s open (open-close
programming option). Activating the input while the gate is moving will
reverse the gate.
Can be programmed to stop the gate while the gate is moving (open-
stop-close programming option).
Fire Department Input
Fully opens the gate when the input is activated. Overrides the Mid-travel
Stop and Auto Close Timer (if either is programmed for the gate). The
gate will lockout in the open position without sounding the alarm. Press
the STOP button to release the lockout.
Open Input
Functions the same as the OPEN button.
Open/Reset Input
Programmable for standard reset loop, Open Counter Mode, or Open
Supervised Mode. See Page 15.
Close Obstruction Input
While the gate is closing, any close obstruction signal will cause the
gate to stop, reverse, and travel to the full open position. Should a open
obstruction input or an open direction inherent entrapment condition
occur prior to the gate reaching the open limit, the operator will lockout
and sound the continuous tone alarm. Another close request will be
required to start the operator again. If after restart, the overload or a
close obstacle happens again before the close limit is reached, the
operator will lockout and sound the alarm. If the auto close timer is set,
when the close obstruction input is cleared, the gate will close when the
auto close timer expires.
Reverse Input
If the reverse input is triggered while the gate is closing, the gate will
reverse to the full open position. If the Auto Close Timer is set, when the
reverse input is cleared, the gate will close when the Auto Close Timer
expires. Not typically used with barrier gates.
Open Loop
Functions the same as the OPEN button.
Reverse Loop
Functions the same as the reverse input. Not typically used with barrier
gates.
Reset Loop
Holds the gate fully open while triggered.
