BI-PARTING GATE SYSTEMS
Bi-parng Gate Systems
Conguring two operators to be a Primary and Secondary pair is easy with the SmartDC Controller. There
is no need to order a special model or any adapters. The area of the board marked Dual Gate employs a
3-wire RS485 serial port for communicaon between primary and secondary operators. See Figure 34.
Power Requirements
When installing a dual-operator system, the following must be adhered to:
• An electrical conduit for interconnecng wires must span between the two operators. The primary-
secondary communicaon wires and any low voltage control wires must be installed in a conduit
that is separate from the high voltage power wires. See “Figure 35. Primary and Secondary Wiring
Connecons” on page 135�
• Complete the installaon of both operators as separate machines and verify that their basic funcons
are correct as solo operators before interconnecng them.
• External control inputs, vehicle detectors and entrapment protecon sensors may be connected to
either gate operator without regard to preference.
• Be sure both operators are running the same soware version. The soware version is available on
the display by pressing the RESET buon on the operator. The soware version appears beneath
the word HYSECURITY. Keep the most current soware loaded. It is available at hps://hysecurity.
com/. Make it part of your maintenance roune to check for soware upgrades on a regular basis.
• Both operators can be connected to the same 20A circuit breaker in the main panel. The wire size
aects operator performance. Use the following chart as a guideline to size wire for the given
distance from the power source to BOTH operators.
