It contains a sensor which is color and spatially corrected to provide a true representation of changes in lighting levels that the human eye perceives. The sensor measures the ambient light that actually falls upon it within a 60. cone extending downward from the sensor (refer to “Field of View” illustration below). This is the light that gets reflected to the ceiling from the walls, floor and furniture.

SPECIFICATION DETAILS Power Consumption Field of View Coverage Output Recommended Mounting Location 1W (42mA @ 24VDC) 60° Cone 0 - 10VDC (0 - 70 footcandles) Directly above work space MOUNTING NOTE: Care must be taken when choosing the mounting location. It is recommended that the sensor be mounted directly above the work space, such as a desk, conference table or computer terminal. Mounting location is important because the ambient light level will be different at different points in the room, depending on the location of the windows, lighting fixtures, wall colors, etc. The ambient light at the doorway can be much less than that at the windows, corners of the room, or especially on the ceiling. Therefore, it is important to measure the ambient light level over the workplace. INSTALLATION The GLS-LCL can either be fastened onto the ceiling surface, flush mounted into the ceiling, or installed in a 4" (102 mm) round or octagonal box, depending on ceiling material and local codes. 1. To fasten the photocell to the ceiling surface, attach the outer shell provided to the ceiling at the desired location using two #4 screws and appropriate anchor hardware, where necessary. For concealed wiring, access to the space above the ceiling is required, as well as a hole in the ceiling above the photocell to connect the wires from the optional GLS-SIM or other Crestron interface device. Make all connections as described in steps 3 through 7. Carefully feed the wires into the hole and press the Photocell body into the outer shell until the rim is flush with the shell. Make all connections as described in steps 3 through 7. Carefully feed the wires into the hole and press the Photocell body into the outer shell until the rim is flush with the shell. 2. To flush mount into the ceiling (only allows concealed wiring, the outer shell is not used), cut a 2" (51 mm) diameter hole through the ceiling. Make all connections as described in steps 3 through 7. Carefully feed the wires back through the hole and press the GLS-LCL into the hole until the rim is flush with the ceiling. 3. Prepare the photocell lead wires by removing 3/4" (19 mm) of insulation from each lead to expose bare copper wire. Make sure the ends of wires are straight. 4. Determine the length of low voltage wires needed to connect power to photocell. Use wires suitable for low-voltage wiring according to local electrical codes. 5. Route low-voltage wires from GLS-LCL location(s) to interface device location(s). (Refer to the wiring diagrams in the next column.) 6. Prepare low-voltage wires by removing 3/4" (19 mm) of insulation from each lead to expose bare copper wire. Make sure the ends of the wires are straight. 7. Connect low voltage wires as shown in wiring diagrams in the next column (black to ground, red to power, and orange to the interface device). Twist strands of each separate wire connection tightly, and push firmly into appropriate wire connector. Screw connector on clockwise ensuring no bare conductor shows below the wire connectors. Secure each connector with electrical tape. 8. Mount the GLS-LCL to the ceiling. INSTALLATION IS COMPLETE. SPECIAL PROGRAMMING To ensure correct processing of the sensor’s output from all interface devices (other than the GLS-SIM), the SIMPL program for the control processor must disable the pull-up resistor built in to the Versiport input connector. This is accomplished by setting the “pu-disable” digital input signal to a “1.” TROUBLESHOOTING PROBLEM POSSIBLE CORRECTIVE CAUSE ACTION Incorrect wiring Refer to the wiring change in ambient light Lights do not respond to between sensor and diagrams in the right level.
