4. Installation

4.1 Mounting the Sensor

The optimal installation height is approximately 20 cm from the ground. Ensure the installation distance between the transmitter and receiver is no less than 2 meters.

To install, first mount the receiver unit. Then, align and mount the blast-off (transmitter) unit. The units should be perpendicular to the protected area and aligned at the same level. Once aligned, the "OFF" light on the receiver should extinguish, indicating proper alignment. Secure the units in place.

Mounting Steps:

1. Use the provided mounting template (or refer to the diagram in the full PDF manual) to mark drill holes.
2. Drill holes as instructed.
3. Secure the sensor units using screws and anchors.
4. Ensure the cable hole is positioned correctly for wiring.

Attention: Avoid direct sunlight on the sensor's lens during installation to prevent interference.

4.2 Connecting the Sensor (Wiring)

The sensor operates on a 12-24V AC/DC power supply. Refer to the wiring diagram in the full PDF manual for proper connections. A summary of the connections is provided below:

Wiring Overview:

• Receiver (R) Connection:
  • Power input (12-24V): Connect to the power supply.
  • -COM: Common ground terminal.
  • Radio sending out: Output terminal for alarm/signal.
  • -OUT: Output terminal for alarm/signal.
  • Relay: Features NO (Normally Open) and NC (Normally Closed) terminals. A jumper setting is available to select between NO and NC.
• Emitter (T) Connection:
  • Two-terminal connection for 12-24V AC/DC power supply.

Ensure correct polarity and voltage when connecting the power supply to both the receiver and emitter units.

5. Operation

The FD Universal Infrared Sensor functions by emitting an infrared beam from the transmitter to the receiver. When an object or person breaks this beam, the sensor triggers an alarm or activates a connected device (e.g., gate opener, security system).

• Automatic Induction: The sensor automatically detects interruptions in the infrared beam.
• High Power Transmission: Ensures a stable and reliable beam over the specified range, even in challenging outdoor conditions.
• Relay Output: The receiver provides a relay output (NO/NC) that can be wired to your gate opener, alarm panel, or other control systems.

Figure 4: The sensor's hemispherical optical lens helps concentrate the beam, making it precise and non-scattering, and includes an automatic glare adjustment system to avoid interference from glare and car headlights.

6. Maintenance

To ensure optimal performance and longevity of your infrared sensor, follow these maintenance guidelines:

• Regular Cleaning: Periodically clean the lenses of both the transmitter and receiver units. Dust, dirt, and debris can obstruct the infrared beam and reduce sensing accuracy. Use a soft, clean cloth and a mild cleaning solution if necessary.
• Alignment Check: Occasionally verify that the transmitter and receiver units remain properly aligned. Misalignment can lead to false alarms or missed detections.
• Environmental Factors: Be aware that heavy rain, dense fog, or strong glare (e.g., from direct sunlight or car headlights) can temporarily affect the sensor's performance. While the sensor has anti-interference features, extreme conditions may still impact its range and reliability.

7. Troubleshooting

If you encounter issues with your infrared sensor, refer to the following troubleshooting tips:

• Sensor Not Reacting / "Not Intelligent Phenomenon":
  • If the transmitter and receiver units are installed too close to each other (e.g., less than 1 meter), the sensor may not react correctly. Try increasing the distance between the units to at least 1 meter.
  • If the issue persists, try removing the condensing lens from the "shoot and receive medium" (optical components). This can sometimes improve sensitivity at very close distances.
• Reduced Range or Unreliable Detection:
  • Bad Weather Conditions: The effective range of the sensor can be reduced by up to 30% in adverse weather conditions such as heavy rain or dust. This is normal behavior.
  • Obstructions: Ensure there are no physical obstructions (e.g., overgrown plants, spiderwebs, dirt on lenses) blocking the infrared beam.
  • Misalignment: Re-check the alignment of the transmitter and receiver units. The "OFF" light on the receiver should be off when properly aligned.
  • Power Supply: Verify that both units are receiving stable power within the specified 12-24V DC/AC range.
• False Alarms:
  • Environmental Interference: Strong glare from direct sunlight or car headlights can sometimes cause false triggers. Ensure the sensors are mounted to minimize direct exposure to such light sources.
  • Vibrations: Excessive vibrations on the mounting surface could cause slight misalignment, leading to intermittent false alarms. Ensure stable mounting.

8. User Tips

• Optimal Placement: For outdoor applications, consider mounting the sensors in a location that minimizes direct exposure to harsh sunlight or heavy rain, even with its IP55 rating and anti-glare features. This can help maintain consistent performance.
• Test Thoroughly: After installation and wiring, always perform thorough tests by breaking the beam at various points and speeds to ensure reliable detection and proper activation of connected devices.
• Secure Wiring: Ensure all wiring connections are secure and protected from weather elements to prevent shorts or disconnections.
