1. Introduction
The Westek SLC9BC Programmable Light Control is designed to convert any standard light socket into an automatic, light-sensing fixture. This device enhances safety and security by automatically turning lights on in low-light conditions and off after a selectable duration or randomly. It is compatible with LED, incandescent, and CFL bulbs up to 100 watts.

Key Features:
- Converts any light socket into an automatic night light.
- Programmable off-times: 2, 5, or 8 hours after dusk, or random off-time for enhanced security.
- Integrated micro-processor for accurate off-time.
- Compatible with LED, incandescent, and CFL bulbs up to 100 watts.
- Suitable for indoor and outdoor use (when protected from direct rain).
2. Setup and Installation
Installation of the Westek SLC9BC is straightforward and requires no special tools. Ensure power to the light fixture is turned off before beginning installation.
Installation Steps:
- Turn off Power: Locate the circuit breaker controlling the light fixture and switch it to the OFF position. Verify that the power is off by attempting to turn on the light.
- Remove Existing Bulb: Carefully unscrew the current light bulb from the socket.
- Install Light Control: Screw the Westek SLC9BC Programmable Light Control into the empty light socket. Ensure it is securely tightened. The device may include a small spring-loaded terminal to help orient the light sensor correctly.
- Install Light Bulb: Screw your desired light bulb (LED, incandescent, or CFL, up to 100 watts) into the socket of the Westek SLC9BC control.
- Restore Power: Return to the circuit breaker and switch the power back to the ON position.

Important Considerations:
- Fixture Compatibility: The SLC9BC adds approximately 2 inches to the height of the bulb. Ensure your fixture has adequate space.
- Light Sensor Placement: The light sensor must be exposed to ambient light to function correctly. Avoid installing in fixtures with opaque or frosted glass, as this can interfere with the sensor's ability to detect light levels, potentially causing the light to turn on prematurely or not turn off.
- Outdoor Use: When used outdoors, ensure the fixture provides adequate protection from direct rain and moisture.
3. Operation
The Westek SLC9BC features a built-in photocell sensor that detects ambient light levels and a programmable timer for automatic shut-off.
Automatic On/Off Function:
- The light control will automatically turn on the connected bulb when it detects low light conditions (dusk).
- The light will remain on until the programmed off-time is reached or until sufficient ambient light is detected (dawn).
Setting the Timer:
The SLC9BC offers several programmable off-time settings. A small switch or dial on the device allows you to select the desired mode:
- Dusk-to-Dawn: The light will turn on at dusk and remain on until dawn.
- 2-Hour Timer: The light will turn on at dusk and turn off approximately 2 hours later.
- 5-Hour Timer: The light will turn on at dusk and turn off approximately 5 hours later.
- 8-Hour Timer: The light will turn on at dusk and turn off approximately 8 hours later.
- Random Off: The light will turn on at dusk and turn off at random intervals to simulate occupancy, enhancing security.

Refer to the markings on your specific unit for the exact switch positions corresponding to each setting.
4. Maintenance
The Westek SLC9BC Programmable Light Control requires minimal maintenance to ensure optimal performance.
- Cleaning: Periodically wipe the exterior of the device with a soft, dry cloth to remove dust and debris. Ensure the light sensor is kept clean and unobstructed. Do not use liquid cleaners or abrasive materials.
- Environmental Conditions: Avoid exposing the device to extreme temperatures, high humidity, or direct water spray unless installed in a properly rated outdoor fixture.
- Bulb Replacement: When replacing the light bulb, always turn off the power to the fixture first.
