BROJEN BJ-960
Wired PIR Sensor Dual Passive Infrared Motion Detector User Manual
Brand: BROJEN | Model: BJ-960
1. Produk Lebihview
The BROJEN BJ-960 Dual Passive Infrared Motion Detector is designed to detect human body infrared spectrum. When a human body moves within its detection range, the sensor receives the heat source signal. Internal circuits and unique lenses process this signal, effectively preventing false alarms from pets. This sensor is widely used in various settings such as banks, warehouses, and homes for enhanced security.
For a complete guide, please refer to the Manual Pengguna Rasmi (PDF).

4. Pemasangan
Proper installation is crucial for optimal performance. Follow these steps:
- Pendakap Pelekap: First, fix the detector bracket securely to the wall using screws.
- Detector Placement: Hang the detector onto the fixed bracket.
- Ketinggian yang disyorkan: The recommended installation height is approximately 2.2 meters (7.2 feet) from the floor.
- Pelarasan Sudut: The detector should be positioned at an angle of 6-12 degrees relative to the wall for best coverage.
- Pertimbangan Alam Sekitar: Avoid installing the detector near objects that can cause rapid temperature changes, such as air conditioners, electric fans, refrigerators, ovens, or windows.
- Garis Penglihatan yang Jelas: Ensure there are no obstructing objects in front of the detector lens.
- Indicator Light Orientation: When installing, ensure the indicator light is positioned above the lens to avoid affecting detection accuracy.

5. Persediaan dan Pendawaian
The BROJEN BJ-960 offers flexible configuration options via jumpers on its PCB to adapt to different system requirements.
- Pulse Count (Jumper J1):
- For general indoor environments, select the first-stage pulse count (tetapan kilang).
- For harsh environments, select the secondary pulse count.
- Alarm Output (Jumper J2 - RELAY):
- To set the alarm output to Biasanya Ditutup (NC), ensure the jumper is inserted (factory setting).
- To set the alarm output to Biasanya Terbuka (TIDAK), unplug the jumper.
- LED Indicator (Jumper J3 - ELD):
- To enable the LED light, ensure the jumper is plugged in (factory setting).
- To disable the LED light, unplug the jumper.
Connect the power and alarm output wires to the appropriate terminals as shown in the diagram below. Ensure all connections are secure and follow local electrical codes.

6. Arahan Operasi
Once properly installed and powered, the BROJEN BJ-960 PIR sensor operates by continuously monitoring its detection area for changes in infrared radiation, which are indicative of human movement.
- Pengesanan: The dual pyroelectric infrared sensor detects the heat signature of a moving body within its 110° detection angle and up to 10 meters distance.
- Pencetus Penggera: Upon detection, the sensor processes the signal. If the movement meets the configured pulse count threshold, the alarm output (NC/NO) will change state, signaling to the connected alarm system.
- Penunjuk LED: If the LED jumper (J3) is enabled, the LED light will illuminate briefly upon detection, providing visual confirmation of activity.
- Kekebalan Haiwan Peliharaan: The unique lens design and internal processing help to minimize false alarms caused by pets up to 25kg.
7. Penyelenggaraan
To ensure the longevity and reliable operation of your BROJEN BJ-960 PIR sensor, follow these simple maintenance guidelines:
- Pembersihan: Periodically wipe the sensor's lens and casing with a soft, dry cloth to remove dust and debris. Do not use abrasive cleaners or solvents.
- Pemeriksaan halangan: Regularly inspect the area in front of the sensor to ensure no new objects are obstructing its field of view.
- Environmental Review: Confirm that no new heat sources or air currents (e.g., from newly installed appliances or open windows) are directly affecting the sensor's detection area, which could lead to false alarms.
- Pemeriksaan Pendawaian: Occasionally check the wiring connections to ensure they remain secure and free from corrosion.
8. Penyelesaian masalah
If you encounter issues with your PIR sensor, consider the following common problems and solutions:
- Tiada Pengesanan:
- Check power supply (DC9-16V).
- Pastikan medan sensor view tidak terhalang.
- Verify correct wiring of the alarm output (NC/NO) to your alarm system.
- Confirm the LED indicator (J3) is enabled to visually confirm detection.
- Penggera Palsu:
- Relocate the sensor away from direct sunlight, heating/cooling vents, or rapidly changing temperatures.
- Adjust the pulse count jumper (J1) to the secondary level for harsher environments to increase stability.
- Ensure the pet immunity feature is effective for your pet's size (up to 25kg).
- Check for any moving objects (curtains, plants) within the detection zone that might be mistaken for human movement.
- LED Tidak Bercahaya:
- Check the LED jumper (J3) on the PCB. Ensure it is plugged in to enable the LED.
- Alarm Output Not Working:
- Verify the RELAY jumper (J2) setting matches the required input type (NC/NO) of your alarm host.
- Inspect the alarm output wiring for loose connections or damage.
If issues persist after troubleshooting, consult the Manual Pengguna Rasmi (PDF) atau hubungi sokongan pelanggan.
