1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of the Perel PIR416 Mini Motion Detector. This device is designed to reliably detect movement within its specified range and angle, making it suitable for enhancing security or automating lighting systems in indoor environments.
2. Safety Information
- Electrical Safety: Always disconnect the main power supply before attempting any installation, wiring, or maintenance. Installation should be performed by a qualified electrician or a competent person if you are unsure about electrical procedures.
- Indoor Use Only: The Perel PIR416 has an IP20 rating, which means it is protected against solid objects larger than 12.5mm but offers no protection against water or moisture. This device is strictly for indoor use in dry environments.
- Voltage Compatibility: Ensure that the power supply voltage matches the requirements of the device (12V DC). Incorrect voltage can damage the unit and pose a safety risk.
- Avoid Obstructions: Do not install the detector near heat sources, air conditioning vents, or in direct sunlight, as these can cause false activations. Ensure the detection area is clear of obstructions.
3. Setup and Installation
The Perel PIR416 Mini Motion Detector is designed for flush mounting, allowing for a discreet installation. Follow these steps for proper setup:

3.3 Wiring Instructions
The device operates on 12V DC. Connect the wires as indicated in the wiring diagram (Image 2):
- Black Wire (V): Connect to the negative (-) terminal of your 12V DC power supply.
- Red Wire (X): Connect to the positive (+) terminal of your 12V DC power supply.
- Brown Wire (Z): This is the output wire. Connect it to the positive (+) terminal of the load you wish to control (e.g., a 12V light or alarm). The negative (-) terminal of the load should be connected directly to the negative (-) terminal of the 12V DC power supply.
Important: Ensure all connections are secure and insulated to prevent short circuits. Always test the circuit with a multimeter before applying power.
3.4 Adjustments
The control unit features DIP switches (visible in Image 1) that allow for adjustment of settings such as sensitivity and time delay. Consult the specific product packaging or a more detailed diagram for the exact function of each switch. Typically, these settings control:
- Sensitivity: Determines how easily the sensor detects motion. Higher sensitivity means it will detect smaller movements or movements at a greater distance.
- Time Delay: Sets the duration for which the connected load remains active after motion is detected and then ceases.
4. Operating Instructions
Once installed and powered, the Perel PIR416 Mini Motion Detector operates automatically:
- The Passive Infrared (PIR) sensor detects changes in infrared radiation (heat) within its detection zone. When a moving object, such as a person, enters this zone, the sensor triggers.
- Upon detection, the device activates the connected load (e.g., turns on a light, triggers an alarm, or activates a security camera).
- The load will remain active for the duration set by the time delay adjustment. If continuous motion is detected, the timer will reset, and the load will remain active until no motion is detected for the set time delay.
- The detection range is up to 8 meters, and the detection angle is 100 degrees, providing broad coverage for indoor spaces.
5. Maintenance
The Perel PIR416 Mini Motion Detector is designed to be maintenance-free. To ensure optimal performance:
- Periodically clean the sensor lens with a soft, dry cloth to remove any dust or debris that might obstruct its field of view.
- Do not use abrasive cleaners or solvents, as these can damage the sensor lens.
6. Troubleshooting
If you encounter issues with your motion detector, consider the following common problems and solutions:
- No Detection:
- Check if the power supply is correctly connected and active.
- Ensure the sensor head is positioned correctly and its view is not obstructed by furniture, curtains, or other objects.
- Verify the sensitivity settings are appropriate for the environment.
- Constant Activation or False Triggers:
- Reduce the sensitivity setting.
- Check for heat sources (e.g., heating vents, direct sunlight, rapidly changing temperatures) or drafts within the detection zone that might cause false triggers.
- Ensure the sensor is not pointing towards areas with frequent, non-human movement (e.g., pets).
- Connected Load Stays On/Off Incorrectly:
- Re-check all wiring connections according to the diagram.
- Verify the time delay setting. If it's set too long, the load will remain on for an extended period.
- Ensure the load itself is functional.
If problems persist after attempting these solutions, contact customer support.
