® Model 916GA Safety Reversing Sensor Kit WARNING For use with models GA600 and GA650 Preparation CAUTION Before getting started, check carton inventory. Be sure power to the opener is disconnected. Due to the variety of gates and mounting applications, conduit and posts are NOT PROVIDED. Refer to your local hardware store for PVC conduit, mounting posts and additional hardware that may be needed. CARTON INVENTORY Anchors (4) WARNING WARNING To prevent SERIOUS INJURY or DEATH: • DISCONNECT power BEFORE installing the safety reversing sensors. • Correctly connect and align the safety sensors. • Install the sensor so beam is NO HIGHER than 24" (61 cm) above ground. • Gate MUST be fully closed BEFORE installing the safety sensors. • This product is for use with Chamberlain GA600 and GA650 gate openers ONLY. Use with other than recommended equipment voids warranty, and may cause property damage or SERIOUS personal INJURY. Grommets (2) FIGURE 1 Safety Sensors Screws (4) IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSOR When properly connected and aligned, the sensor will detect an obstacle in the path of its electronic beam. The sending eye transmits an invisible light beam to the receiving eye. If an obstruction breaks the light beam while the gate is CLOSING, the gate will stop and reverse to full open position. If an obstruction breaks the light beam while the gate is OPENING, the gate will stop. 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. Either 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 reversing sensors must be securely fastened to a solid surface such as a metal or treated wood post (not provided). The invisible light beam path must be unobstructed during normal operation of the gate (Figure 1). NOTE: Two kits can be used for CLOSE and OPEN safety sensors (Figure 2).

The close safety sensors will also require a saw cut or trench across the driveway for wiring. 1. Disconnect power to opener. 2. Use a metal or treated wood post (not provided) to elevate the sensors. The lenses should be no higher than 24" (61 cm) above the ground. 3. Measure and position the safety sensors at the same height above the ground. 4. Securely fasten sensors to post with hardware provided (Figure 3). 5. Bury safety reversing sensor wires. a. OPEN safety sensors: • Dig a narrow trench about 6" (15 cm) deep from the sensor mounting post to the control box. Make sure not to damage any wires already trenched. b. CLOSE safety sensors: • Saw cut or trench across the driveway for wiring. • Dig a narrow trench about 6" (15 cm) deep from the sensor mounting post to the control box. Make sure not to damage any wires already trenched. 6. Locate knockout on the bottom of the control box. Measure and cut a piece of PVC conduit (not provided) to install from the control box to the bottom of the trench. Route the sensor wires through the conduit with 1/2" (12 mm) sealed fitting. 7. Connect wires in the control box. a. OPEN safety sensors: • Connect wires to P7 terminal. 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. b. CLOSE safety sensors: • Connect wires to P9 terminal. This will reverse a closing gate to the full open position (open limit). This will have no effect on a gate opening. The Timer-to-Close will not reactivate at the open limit. 8. Reconnect power to opener. The indicator lights in both the sending and receiving eyes will glow steadily if wiring connections and alignment are correct. 9. Alignment is necessary if the LED flashes (when the invisible light beam is not blocked). Loosen the receiving eye so that slight movement is possible. Adjust the sensor vertically and/or horizontally until the red LED is lit and no longer flashes. Close Safety Sensors Test the Safety Reverse 1. Press the remote control button to open the gate. 2. Place an obstruction in the path of the gate. 3. Press the remote control button to close the gate. The gate should stop or stop and reverse depending on the application. The gate opener will not close from a remote if the indicator light in either sensor is off (alerting you to the fact that the sensor is misaligned or obstructed). If the unit continues to fail the Safety Reverse Test, call for a trained gate systems technician. Troubleshooting If the sending or receiving LEDs do not light up after installation, please check the following: a. Power supply to the opener. b. Short-circuit in the black/white cable. This can happen beneath clamps or at the connecting terminals. c. Incorrect wire connections between the sensor and opener. d. Interruption to the power supply circuit (broken wire). If both sensors are flashing: a. Align sensors. b. Remove obstruction. © 2006, The Chamberlain Group, Inc. All Rights Reserved
