The photocell sensor is a safety device that prevents the gate from hitting a vehicle or pedestrain when the
gate is closing. The photocell sensor emits an invisible retroreflective infrared beam that detects when
objects passes through.
1. Plug the photocell sensor cable to the back of the control box, behind the circuit board with a green input
with the label: “MON-OPEN”, “MON-CLOSE”, “COMMON”, “MON-24DC”. (Figure A)
2. Press the reset button on the control box circuit board.
3. Use the two included mounting brackets to mount the photocell sensor on a post or wall OUTSIDE your
gate, 21” from the ground.
4. Press the orange button on the photocell sensor to turn on the alignment laser.
5. Mount the reflector to the opposite side. Make sure it is level with the photocell sensor (Figure C) and the
alignment laser beam hits inside the circle of the reflector. (Figure B)
6. Press the orange button on the photocell sensor to turn off the alignment laser.
IMPORTANT!!!
