Seco-Larm E-936-S45RRGQ Retro Reflective Photoelectric Beam Sensor User Manual

Product Overview

The Seco-Larm E-936-S45RRGQ is a retro-reflective photoelectric beam sensor designed to establish a secure perimeter. It operates by emitting an invisible infrared beam which, when broken, triggers an alarm signal. The sensor is housed in a rugged, weatherproof (IP66) enclosure, making it suitable for both indoor and outdoor installations. Status is indicated by integrated LEDs.

This sensor is versatile and can be used for various applications, including driveway monitoring, gate operator safety (conforms to UL325-2016 with a 10-ohm resistor), and as a parking assist indicator in garages.

Package Contents

Verify that all components are present in the package:

• Transmitter/Receiver (Sensor Unit)
• Sensor Mounting Brackets
• Round Reflector
• Reflector Hood
• 10-Ohm Resistor

Note: A security system or alarm device is required to receive alerts when the beam is activated.

Setup and Installation

The E-936-S45RRGQ sensor is designed for straightforward installation using the included mounting hardware. It is suitable for pole mounting.

Mounting

Select a stable mounting location for both the sensor unit and the reflector. Ensure a clear line of sight between the sensor and the reflector. The sensor has an adjustable sensing range from 6 inches (0.15m) to 45 feet (14m).

Attach the sensor unit and the reflector using the provided mounting brackets. The reflector hood should be used to protect the reflector from environmental elements.

Wiring

The sensor comes with a pre-wired 6ft (1.8m) cord. Connect the sensor to a power source and your alarm or control system according to the following specifications:

• Supply Voltage: 12-30V DC/AC 60Hz, 100mA
• Trigger Output: SPDT Relay Output (NO/NC/COM)
• Switching Capacity: 2A at 30VAC/VDC

For gate operators requiring monitoring, use the included 10-ohm resistor as per UL325-2016 compliance.

Alignment

After mounting and wiring, align the sensor with the reflector. The sensor features a Yellow LED which assists in alignment. Adjust the sensor's position until the Yellow LED indicates optimal alignment, typically by being steadily lit or off, depending on the specific alignment state (refer to detailed wiring diagram in the full product manual for exact LED behavior during alignment).

Operation

Once properly installed and aligned, the sensor continuously monitors the infrared beam between itself and the reflector. When an object breaks this invisible beam, the sensor's internal relay is triggered, sending an alarm signal to the connected security system or control device.

• Response Time: The sensor reacts within 10 milliseconds of the beam being broken.
• Trigger Indication: A Red LED on the sensor illuminates when the beam is triggered, providing a visual indication of activation.

Typical applications include:

• Perimeter security for driveways, gates, and entry points.
• Safety beam for automatic gate operators.
• Vehicle detection for access control or alerts.
• Parking assistance in garages.

Maintenance

The E-936-S45RRGQ is designed for minimal maintenance due to its weatherproof (IP66) construction and durable materials. However, periodic checks are recommended to ensure optimal performance:

• Cleaning: Regularly inspect the sensor lens and the reflector surface for dirt, dust, spiderwebs, or other obstructions. Clean gently with a soft, damp cloth. Avoid abrasive cleaners.
• Alignment Check: Periodically verify that the sensor and reflector remain properly aligned. Environmental factors or physical impacts can sometimes shift their positions.
• Environmental Conditions: The sensor is rated for operating temperatures between -4°F to 131°F (-20°C to 55°C). Ensure it is not exposed to conditions outside this range for prolonged periods.

Troubleshooting

If the sensor is not functioning as expected, consider the following troubleshooting steps:

• No Trigger/False Alarms:
  • Check Alignment: Ensure the sensor and reflector are perfectly aligned. The Yellow LED should indicate proper alignment. Re-adjust if necessary.
  • Clear Obstructions: Verify that there are no physical obstructions (e.g., foliage, debris, snow, ice) blocking the beam path or covering the sensor lens/reflector.
  • Power Supply: Confirm that the sensor is receiving the correct supply voltage (12-30V DC/AC).
  • Wiring: Inspect all wiring connections for looseness or damage. Ensure the trigger output is correctly connected to your alarm system.
• Sensor Not Powering On:
  • Power Source: Check the power source for functionality.
  • Wiring: Verify power connections to the sensor.
• Intermittent Operation:
  • Environmental Factors: Strong sunlight, heavy rain, or fog can sometimes affect beam stability.
  • Vibrations: Ensure the mounting surfaces for both the sensor and reflector are stable and free from excessive vibrations.

If issues persist after these steps, contact Seco-Larm technical support for further assistance.
