Chamberlain Home Security System 916GA User Manual

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.
