WIRE ACCESSORIES TO CONTROL BOARD TERMINALS OPEN and COMM CLOSE and COMM STOP and COMM THREE BUTTON CONTROL STATION FUNCTION WIRING EXAMPLE 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). + + + - N.C. TERMINALS FIRE DEPT (-) and OPEN (+) FIRE DEPARTMENT FUNCTION WIRING EXAMPLE 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-to-Close. 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 FUNCTION WIRING EXAMPLE EXIT and COM 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. + - • Opens a closing gate and holds open an open gate, if maintained, pauses Timer-to-Close at OPEN limit. + - SHADOW and COM This input is used for external shadow loop detector when loop + is positioned under the swing of the gate. • Holds open gate at open limit • Only active when the gate is at the OPEN limit, disregarded at all other times • Pauses Timer-to-Close at OPEN limit INTERRUPT and COM This input is used for photoelectric sensors and external interrupt loop detector when loop is on the outside of the gate. • Holds open gate at open limit • Stops and reverses a closing gate to open limit • Pauses Timer-to-Close at OPEN limit, activates quick close and anti-tailgate features when enabled on the expansion board 25
