Introduction
This manual provides comprehensive instructions for the safe installation, operation, and maintenance of your V-TAC VT-5087 PIR Infrared Motion Sensor. Please read this manual carefully before installation and retain it for future reference. This sensor is designed for ceiling mounting and automatically controls lighting based on detected motion.
Key Features
- PIR (Passive Infrared) Motion Detection
- 360-degree Detection Angle
- Ceiling Mount Design
- Adjustable LUX (Ambient Light) Sensitivity
- Adjustable TIME Delay
- Maximum Load: 1000W (LED) / 2000W (Traditional Lighting)

Figure 1: V-TAC VT-5087 PIR Infrared Motion Sensor. This image highlights the sensor's capabilities, including a maximum load of 1000W for LED lighting, automatic on/off based on motion, and a 'SUN' setting for daylight operation (only works when natural light is 3 lux or less). Detection motion speed is 0.6-1.5m/s.
Setup and Installation
Important Safety Information: Installation must be performed by a qualified electrician and in accordance with all local electrical codes. Ensure power is disconnected at the circuit breaker before beginning installation to prevent electric shock.
Mounting Location
- Choose a ceiling location where the sensor can cover the desired detection area without obstruction.
- Avoid mounting near heat sources (e.g., air vents, heaters) or direct sunlight, as these can cause false triggers.
- Ensure the mounting surface is stable and can support the sensor.
Wiring Instructions
- Turn off the main power supply at the circuit breaker.
- Carefully remove the outer casing of the sensor to access the wiring terminals.
- Connect the live (L), neutral (N), and load (L') wires according to the diagram provided on the sensor or in the packaging. Typically:
- L: Live input from power supply
- N: Neutral input from power supply and neutral to load
- L': Switched live output to the light fixture (load)
- Securely fasten the sensor to the ceiling using the provided screws and anchors.
- Replace the outer casing.
- Restore power and test the sensor.

Operating Instructions
The V-TAC VT-5087 sensor features two adjustable controls: LUX and TIME. These allow you to customize the sensor's behavior to suit your environment and preferences.
Adjustment Knobs
- LUX Control: This knob adjusts the ambient light threshold at which the sensor will activate.
- Turn towards the SUN symbol for activation in both daylight and darkness (e.g., >2000 LUX).
- Turn towards the MOON symbol for activation only in low light conditions (e.g., <3 LUX).
- TIME Control: This knob sets the duration the light remains on after motion is detected and then stops.
- Adjust from minimum (approx. 10 seconds) to maximum (approx. 15 minutes).
- The timer resets if motion is detected again before the set time expires.

Detection Range and Angle
The sensor offers a 360-degree detection angle, making it suitable for central ceiling placement. The maximum detection distance is approximately 6 meters (up to 8 meters at <24°C). The detection motion speed is 0.6-1.5 m/s.

Maintenance
The V-TAC VT-5087 PIR sensor requires minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Cleaning: Gently wipe the sensor lens and housing with a soft, dry cloth. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the unit.
- Obstructions: Periodically check that there are no new obstructions (e.g., furniture, decorations) blocking the sensor's field of view.
- Power: Always disconnect power before performing any cleaning or inspection to prevent electric shock.
Troubleshooting
If you experience issues with your V-TAC VT-5087 PIR sensor, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on when motion is detected. |
|
|
| Light stays on continuously or turns on randomly. |
|
|
| Detection range is too short or inconsistent. |
