Refer to the sensor manufacturer’s instructions for information
about installing these devices on a vehicular gate.
Make sure the power switch to the operator is
turned off before connecting safety device wiring
to the terminal blocks. Unplugging the transformer
does not turn power to the operator OFF.
Non-Contact Sensor Connection:
Connect one of the non-contact sensor dry contact output wires
to the COMMON (COM) terminal and the other to the
SAFETY terminal on the GTO/PRO® 4000 control board.
This input is ONLY monitored when the gate is
closing. Activating the non-contact sensor
(obstructing the safety beam path) will cause the
gate to reverse to the fully open position.
Non-Contact Sensors (photo beams)
The GTO/PRO® 4000 can also accept "Safety" input from normally open "dry-contact" output devices such as photo beams
connected to the SAFETY input terminal.
If not installing a non-contact sensor skip to next section.
PLEASE NOTE: Non-contact sensors are not included with the GTO/PRO® 4000.

Shadow Loop Connection:
Connect one of the shadow loop wires to the COMMON
(COM) terminal and the other to the SHADOW LOOP terminal
on the GTO/PRO® 4000 control board.
The shadow loop is a detector located with the moving path of
the gate to prevent the gate from closing when a vehicle in the
path.
