Renkforce 751560 Dual Motion Sensor Instruction Manual

1. Product Overview

The Renkforce 751560 Dual Motion Sensor is a passive infrared (PIR) detector designed for reliable motion detection in various environments. It features a dual sensor for enhanced accuracy and reduced false alarms, making it suitable for security and surveillance applications in private, commercial, and industrial settings. The sensor offers selectable Normally Open (NO) and Normally Closed (NC) operation, allowing integration with different alarm systems or for controlling lighting, such as staircase lights. It also includes an anti-tamper mechanism for added security.

2. Safety Instructions

Read this manual thoroughly before installation and operation.
Only qualified personnel should perform installation and wiring.
Ensure the power supply is disconnected before any installation or maintenance work.
Do not expose the device to extreme temperatures, humidity, or direct sunlight.
Avoid mounting the sensor near heat sources or objects that may cause rapid temperature changes, as this can lead to false alarms.
Do not paint or cover the sensor lens, as this will impair its functionality.
This device is designed for indoor use only.

3.2. Mounting Location

Choose a suitable location for the motion sensor, typically in a corner or on a wall, where it can cover the desired detection area without obstruction. Avoid aiming the sensor directly at windows, heating vents, or areas with significant air currents.

3.3. Installation Steps

Prepare the Mounting Surface: Mark the drilling points for the mounting bracket on the wall.
Drill Holes: Drill holes at the marked positions and insert the wall plugs (if necessary).
Attach Mounting Bracket: Secure the mounting bracket to the wall using the provided screws.
Connect Wiring: Open the sensor housing carefully. Connect the power supply (12V DC) and alarm output wires to the designated terminals inside the sensor. Ensure correct polarity.
Set NO/NC Mode: Configure the sensor's output mode (Normally Open or Normally Closed) according to your alarm system's requirements using the internal jumper or switch.
Attach Sensor to Bracket: Mount the sensor unit onto the attached bracket. Ensure it clicks securely into place.
Adjust Detection Angle: Adjust the sensor's angle to cover the desired detection area.

4. Operating Instructions

4.1. Powering On

Once installed and wired, apply 12V DC power to the sensor. The sensor will typically undergo a brief initialization period (e.g., 30-60 seconds) during which its LED indicator may flash. Avoid movement in the detection area during this time.

4.2. Detection and Alarm Output

The dual PIR sensor detects infrared radiation changes caused by moving objects within its 12-meter range. Upon detection, the sensor's alarm output will change state (either open or closed, depending on your NO/NC setting) to trigger the connected alarm system or device.

4.3. Anti-Tamper Function

The sensor is equipped with an anti-tamper switch. If the sensor's housing is opened or forcibly removed from its mounting bracket while powered, this switch will activate, triggering a separate tamper alarm output to your connected system.

5. Maintenance

Cleaning: Periodically wipe the sensor lens and housing with a soft, dry cloth to remove dust and dirt. Do not use abrasive cleaners or solvents.
Testing: Regularly test the sensor's functionality by walking through its detection area to ensure it triggers the connected alarm system.
Inspection: Visually inspect the wiring and mounting for any signs of damage or loosening.

6. Troubleshooting

Problem	Possible Cause	Solution
Sensor does not detect motion.	No power supply. Incorrect wiring. Sensor lens obstructed or dirty. Sensor aimed incorrectly.	Check 12V DC power connection. Verify wiring connections and polarity. Clean the sensor lens. Adjust sensor angle to cover the desired area.
False alarms.	Sensor mounted near heat sources (e.g., radiators, direct sunlight). Air currents (e.g., from vents, open windows). Small animals in detection area.	Relocate the sensor away from heat sources. Ensure stable environmental conditions. Adjust sensitivity (if available, check manual for specific model features) or reposition to exclude pets.
Tamper alarm triggers unexpectedly.	Sensor housing not securely closed. Sensor not securely attached to mounting bracket. Faulty tamper switch.	Ensure the housing is properly closed. Re-attach the sensor firmly to its bracket. Contact support if the issue persists after checking physical connections.
