PHOTOELECTRIC DUAL BEAM DETECTOR R4222

PHOTOELECTRIC
DUAL BEAM DETECTOR
Owners Manual
R4222
The GTO Access Systems Photoelectric Dual Beam Detector uses dual beam and through-beam technology
to reduce false detections when detecting obstructions. When the beams detect the presence of a moving
object, the detection will cause the gate(s) to stop and reverse to the fully open position. As long as the
beam is obstructed the gate(s) will remain open. Not compatible with solar powered gate operators.
For use with all GTO Access Systems and Mighty Mule AC and DC powered gate operators.

Mounting Cautions
Be sure that the optical axis is never obstructed. (The optical axis is both the vertical and horizontal
range of detection, or beam, between the transmitter and receiver)
Do not mount the detector in the following conditions:
Where the mounting
surface is unstable.
Spread of Beam
Mounting Height
Where obstructions (plants, fences, etc.)
are between the receiver and the sender.
Where sunlight and headlights shine
directly into the front of the receiver.

Connecting Photo Beams to GTO Access Systems
and Mighty Mule Control Boards
IMPORTANT: DO NOT use Photo Beams on systems charged with solar panels.
Make sure the power switch to the opener is turned off before connecting safety device
wiring to the terminal blocks. Unplugging the transformer does not turn power to the
opener OFF.
Wiring Precautions
• Wire with 16awg minimum (RB509)
• 300 ft (91.4m) max length
• Be sure to capture the wire ends under
the wire clamp plates.
• Avoid frayed ends on wires that might
produce a short circuit.
• Be careful not to overtighten the screws
as this may strip the threads in the plastic

Beam Alignment
Adjusting Optical Axis with the Viewfinder
1. With the POWER connected and the
RECEIVER and TRANSMITTER covers
removed adjust the horizontal pivot,
and the vertical adjustment screw using
the built-in viewer. Look through the
viewfinder on either side and adjust to put
the opposite sensor in the middle of the
cross-hairs in the view finder. The GOOD
LED should be on. (Adjust the light axis
until the indication lamp is on.)

Adjusting Optical Axis with a Voltmeter
If you have a voltmeter, the best method of adjusting the optical axis
is to measure the signal level at the test probe points.
1. Insert the voltmeter probes into the test points on the side of the receiver.
2. Adjust the horizontal angle and vertical angle until the voltage is at
maximum.
3. If a voltage of 1.2v or above cannot be reached, the transmitter and/or
receiver should be readjusted.

Beam Interruption Time Adjustment
Adjusts the amount of time between the beam being broken and the
normally open relay closing. Adjust time adjustment dial from (1) detecting
fast moving objects to (5) detecting slow moving objects depending on
your type of application and environment.
The factory setting is set to 1 to detect fast moving objects.

VERIFY CORRECT OPERATION
After installation, confirm
correct operation by suitable
walking tests. Refer to the
appropriate LED indicators
during the walking test and
