Loop Detector-Swinging Gate Contr. Enter & Exit (1500P300)

Loop Detector System for a Swinging Gate with Controlled Entrance and Exit

Controlled Entrance

1. Vehicle approaches entrance gate and driver inserts a coded card into the card reader (or punches the code into a keypad). This transmits an impulse to the Loop Detector timer actuating the Electric Operator to open the gate.
2. Vehicle proceeds through the gate opening passing over underground Safety Loop #1 and #2. After a pre-determined period, the time sends another impulse to the Electric Operator to close the gate. In the event the vehicle has not yet cleared the gate area (Safety Loop #1 and #2), the Loop Detector will re-cycle the timer, preventing the gate from closing until the area is cleared.

Controlled Exit

1. Vehicle approaches the exit and the driver inserts a coded card into the card reader (or punches the code into a keypad). This transmits an impulse to the Loop Detector timer, the actuating the Electric Operator to open the gate.
2. Exiting vehicle proceeds through the gate opening passing over underground Safety Loop #1 and #2. After a predetermined period the timer sens anotehr impulse to the Electric Operator to close the gate. In the event the vehicle has not yet cleared the gate area (Safety Loops #1 and #2), the Loop Detector will re-cycle the timer, preventing the gate from closing until the area is cleared.
