2.3 LOW VOLTAGE WIRING
Controls must be far enough from the barrier operator so that the user is prevented from coming in
contact with the operator or arm while operating the controls. Outdoor or easily accessible controls
should have a security feature to prevent unauthorized use.
2.3.1 CONTROL WIRING
• Connect optional control devices to the operator terminal strip as shown. Be sure that all
electrical connections are made in accordance with local electrical codes. Use 18 AWG wire
for all low voltage wiring, maximum distance 3000 feet. Use a low voltage surge suppresser,
DoorKing P/N 1878-010 if low voltage wire runs exceed 1000 feet. All inputs to the terminal
strip must be NORMALLY OPEN.
• Do not power any devices from the circuit board other than a low voltage radio receiver as
shown. Additional accessory items such as card readers or keypads must be powered from
their own power transformer.
• If this operator is part of a Perimeter Access Management System (PAMS), refer to your
PAMS wiring manual and section 2.3.3 for interface wiring to the swing or slide gate operator.
