A second photocell sensor can be installed inside the gate to monitor the OPEN cycle.
This secondary photocell sensor goes inside your property, past the gate’s fully open position. if the photo-
cell sensor’s cable isn’t long enough you will need to extend (splice) the wires by joining them with another
20 - 22 AWG wire for the secondary photocell sensor to be able to reach the gate operator input.
Secondary Photocell Sensor Wiring
Use the same green terminal block input as your primary photocell sensor. Each input can have more than 1
wire inserted. Different model photocell sensors contain 3 or 4 wires.
3 Wires: MON-OPEN (Brown), COMMON (Blue), MON-24VDC (Grey)
4 Wires: MON-OPEN (Brown), COMMON (Blue/White), MON-24VDC (Grey)
Depending on how many your photocell sensor contains, follow the wiring diagram below:
