THE PROTECTOR SYSTEM®
SAFETY SENSORS MODEL 916GA
®
The Safety Sensor Kit is compatible with Chamberlain® Gate Access
Systems GA400D, GA420D, and GA200D. The Safety Sensors are
designed to detect an obstacle in the path of the electronic beam and
stop the gate operator.
WARNING
To prevent SERIOUS INJURY or DEATH:
• Disconnect ALL electric and battery power BEFORE performing
ANY service or maintenance.
• Correctly connect and align the safety sensors.
• Install the sensor so beam is NO HIGHER than 24" (61 cm) above
ground.
• This product is for use with Chamberlain® GA400D, GA420D, and
GA200D gate operators ONLY.

IMPORTANT INFORMATION ABOUT THE SAFETY SENSORS
When properly connected and aligned, the sensor will detect an obstacle
in the path of its electronic beam.
Entrapment
Danger
The sensors must be installed so that the sending and receiving eyes
face each other across the gate, no more than 24" (61 cm) above the
ground. The sensors can be installed on the left or right of the gate as
long as the sun never shines directly into the receiving eye lens.
The safety sensors must be securely fastened to a solid surface such as
metal or a treated wood post (not provided). The light beam path must
be unobstructed during normal operation of the gate.
NOTE: Due to the variety of gates and mounting applications, PVC
conduit, wire, mounting hardware and posts are not provided. Refer to
your local hardware store for additional hardware.
APPLICATIONS
CLOSE Safety Sensors
ENTRAPMENT SAFETY SENSORS
This will pause an opening gate until the obstruction has been
removed. Upon removing the obstruction, the gate will continue to
open. This will have no effect on the gate closing.
Inside Prop
OPEN (PHOTO EYE/IR) SAFETY SENSORS
•
GA400D/GA420D - This will pause an opening gate until the
obstruction has been removed. Upon removing the obstruction, the
gate will continue to open. This will have no effect on the gate closing.
•
GA200D - This will stop a closing or opening gate, once the
obstruction is removed the gate will continue to operate normally
upon the next command given.
CLOSE (PHOTO EYE/IR) SAFETY SENSORS
•
GA400D/GA420D - This will reverse a closing gate to the full open
position (open limit). This will have no effect on a gate opening.
•
GA200D - This will stop a closing or opening gate, once the
obstruction is removed the gate will continue to operate normally
upon the next command given.

ASSEMBLE SAFETY SENSORS
Insert hex head bolt through safety sensor and slide safety sensor into
bracket. Secure with wing nut.
MOUNT SAFETY SENSORS
Mount safety sensor assembly to post using appropriate hardware (not
provided). Safety sensors must be installed no higher than 24" (61 cm)
above the ground.
NOTE: Install safety sensor assembly with the two holes in the bracket
facing up and the LEDs visible at the top.

NOTE: If the safety sensor wires need to be extended, the polarity must
be maintained when connecting the safety sensors to the control board.
The black striped wire connects to the negative (-) terminal and the red
wire connects to the positive (+) terminal.

1. Reconnect power and batteries to the operator. The indicator lights in
both the sending and receiving eyes will glow steadily if wiring
connections and alignment are correct.
NOTE: The sending eye indicator light will glow regardless of alignment
or obstruction. If the indicator light in the receiving eye is off, dim, or
flickering (and the invisible light beam path is not obstructed), alignment
is required.

The gate operator will not function from a remote control if the indicator
light in either sensor is off indicating the sensor is misaligned or
obstructed. If the system continues to fail the test, call for a trained gate
systems technician.

TROUBLESHOOTING
Close Safety Sensors
If the sending or receiving LEDs do not light up after installation, please
check the following:
Indicator Light
• Power supply to the operator. Operator may be in stand-by mode,
press the reset button to wake up the operator. Verify voltage at
inputs.
• A short in the wires. Check wires.
• Incorrect wire connections between the safety sensors and operator.
Verify wiring.
• A broken wire. Check wires.
If both sensors are flashing:
• Align sensors.
• Remove obstruction.
• GA200D - Disconnect safety sensors then turn power on unit.
• GA400D/GA420D - Erase the programming for the safety
sensors - remove safety sensor. Press learn limits button then
press reset button.
