WIRE ACCESSORIES TO CONTROL BOARD All control wiring used to connect external devices to Class 2 circuits of the operator must be (QPTZ) Power-Limited Circuit Cables, Type CL2, CL2P, CL2R, or CL2X or other cable with equivalent or better electrical, mechanical, and flammability ratings. Three Button Control Station TERMINALS OPEN and COMM CLOSE and COMM STOP and COMM FUNCTION Opens a closed gate. Hard open (maintained switch overrides external safeties and resets alarm condition). If maintained, pauses Timer-to-Close at OPEN limit. Opens a closing gate and holds open an open gate (within line-of-sight). Closes an open gate. Hard close (maintained switch overrides external safeties and resets alarm condition within line-of-sight) Stops a moving gate. Hard stop (maintained switch overrides Open and Close commands and resets alarm condition). If maintained, cancels Timer-to-Close at OPEN limit. Overrides Open and Close commands (within line-of-sight). WIRING EXAMPLE Fire Department TERMINALS FIRE DEPT (-) and OPEN (+) FUNCTION FIRE DEPT and OPEN terminals act as a hard open. Maintained input overrides (ignores) external safeties (photoelectric sensor and edge), pauses Timer-to-Close. Momentary input logic as single button control and safeties remain active, re-enables Timer-toClose. WIRING EXAMPLE Loops The Loop terminals are used for connecting loops and various control devices such as telephone entry keypads, vehicle probes, etc. Connect the accessory to the terminals based on how the accessory should function. TERMINALS EXIT and COM FUNCTION This input is a soft open command (maintained switch does not override external safeties and does not reset alarm condition). Used for exit probe, telephone entry, external exit loop detector, or any device that would command the gate to open. WIRING EXAMPLE SHADOW and COM l Opens a closing gate and holds open an open gate, if maintained, pauses Timer-to-Close at OPEN limit. This input is used for external shadow loop detector when loop is positioned under the swing of the gate. INTERRUPT and COM l Holds open gate at open limit l Only active when the gate is at the OPEN limit, disregarded at all other times l Pauses Timer-to-Close at OPEN limit This input is used for photoelectric sensors and external interrupt loop detector when loop is on the outside of the gate. l Holds open gate at open limit l Stops and reverses a closing gate to open limit l Pauses Timer-to-Close at OPEN limit, activates quick close and anti-tailgate features when enabled on the expansion board 28
