4. Setup and Installation
Proper installation is crucial for optimal performance and safety. It is recommended that installation be performed by a qualified electrician.
4.1 Package Contents
Verify that all components are present before beginning installation:
- RAB Lighting STL200 Stealth Sensor unit
- Mounting hardware (typically includes gasket, mounting plate, screws)
- Instruction sheet (this document)
4.2 Mounting
The STL200 is designed for pole mount applications. Ensure the mounting surface is stable and can support the sensor and any connected lighting fixtures.
- Turn off power at the circuit breaker or fuse box before starting.
- Attach the mounting plate securely to the desired location.
- Feed the sensor wires through the mounting hole.
- Connect the wires as per the wiring diagram below.
- Secure the sensor unit to the mounting plate.
4.3 Wiring
Connect the sensor wires to the building's electrical system and the light fixture wires:
- Black Wire: Connect to 120V AC Line (Hot).
- White Wire: Connect to Neutral.
- Red Wire: Connect to the load (light fixture).
Ensure all connections are secure and insulated with approved wire connectors.
5. Operation
Once installed and powered, the STL200 sensor will begin operation. It features adjustable settings for optimal performance.

Figure 2: Sensor Adjustment Dials. This image shows a close-up of the sensor's underside, revealing three adjustment dials for controlling settings like time and sensitivity. The lens and grill are also visible.
5.1 Sensitivity Adjustment
The sensor's sensitivity can be adjusted to detect motion from 30% to 100% of its maximum range. Use a small screwdriver to turn the 'Sensitivity' dial located on the underside of the sensor. Adjusting the sensitivity helps prevent false triggers from small animals or distant movements.

Figure 3: Adjustable Sensitivity. This diagram illustrates how the sensor's detection sensitivity can be adjusted from 30% to 100% of its maximum range, allowing for fine-tuning of motion detection.
5.2 Time Adjustment
The 'Time' dial controls how long the connected light fixture remains on after motion is no longer detected. Settings typically range from a few seconds to several minutes. Adjust this to suit your preference and application.
5.3 LED Indicator
The sensor includes an LED indicator. During daylight hours, it illuminates when motion is detected. At night, it glows red, indicating the sensor is active and ready to detect motion.
5.4 Manual Override
The STL200 features a protected manual override function. This allows the user to keep the light on continuously, bypassing the motion detection. The sensor will automatically reset to motion detection mode after a set period or when power is cycled.

Figure 4: Advanced Features. This image highlights key features such as Radio Frequency Immunity, 6000 Volt Surge Protection, and a Protected Manual Override with Auto Reset, ensuring reliable and durable operation.
6. Detection Patterns
The STL200 sensor provides a 200-degree field of view for motion detection. This wide coverage ensures that a significant area is monitored, reducing blind spots.

Figure 5: Detection Patterns. This diagram illustrates the distinct detection patterns for various RAB Stealth Sensors. The STL200 model shows a 200-degree detection arc extending up to 100 feet, providing broad coverage.
7. Maintenance
The RAB Lighting STL200 Stealth Sensor requires minimal maintenance to ensure continued performance.
- Cleaning: Periodically clean the sensor lens with a soft, damp cloth to remove dust, dirt, or debris that may obstruct its field of view. Do not use abrasive cleaners.
- Inspection: Annually inspect the sensor and its wiring for any signs of damage, wear, or loose connections.
8. Troubleshooting
If your STL200 sensor is not functioning as expected, refer to the following common issues and solutions:
- Light does not turn on:
- Check if power is supplied to the sensor and light fixture.
- Verify wiring connections are correct and secure.
- Ensure the light bulb is functional.
- Adjust sensitivity settings; it may be set too low.
- Confirm the sensor is not obstructed.
- Light stays on continuously:
- Check if the manual override function is active. Cycle power to reset.
- Reduce sensitivity if the sensor is detecting unwanted motion (e.g., trees swaying, traffic).
- Ensure the sensor is not aimed at heat sources or reflective surfaces.
- Light turns on for no apparent reason (false triggers):
- Lower the sensitivity setting.
- Adjust the sensor's angle to exclude areas with frequent unwanted motion.
- Ensure the sensor is not exposed to direct sunlight or rapid temperature changes.
