1. Introduction
The Optex BX-80NR is a high-performance wireless outdoor dual passive infrared (PIR) barrier detector designed to provide reliable perimeter security. It creates a multi-layered detection barrier, ideal for protecting windows, doors, and other vulnerable outdoor areas. This manual provides detailed instructions for the proper installation, operation, and maintenance of your BX-80NR detector to ensure optimal performance and longevity.
2. Safety Information
Please read all safety instructions carefully before installing or operating the device. Failure to follow these instructions may result in damage to the product, property, or personal injury.
- Ensure the power source is disconnected before performing any installation or maintenance.
- Do not attempt to disassemble or modify the detector beyond what is described in this manual.
- Install the detector in a location where it is protected from direct impact and extreme weather conditions.
- Use only the specified battery type (CR2 lithium 3V) for power.
- Keep the device away from strong electromagnetic fields.
- Dispose of batteries according to local regulations.

4. Setup and Installation
4.1 Mounting Considerations
The BX-80NR is designed for wall mounting. Proper placement is crucial for effective detection and to minimize false alarms. Consider the desired detection area and potential obstructions.
- Mount the detector at a height that allows the detection beams to cover the desired area without being obstructed by vegetation, fences, or other objects.
- Avoid aiming the detector directly at reflective surfaces or heat sources.
- Ensure the mounting surface is stable and secure.

4.2 Powering the Device
The BX-80NR is battery-powered. It requires a 3V CR2 lithium battery (not included). Ensure correct polarity when inserting the battery.
- Open the battery compartment cover.
- Insert the CR2 lithium battery, observing the polarity markings (+/-).
- Close the battery compartment cover securely.
4.3 Initial Settings and Adjustments
After mounting and powering the device, perform initial adjustments to optimize detection performance.
- Detection Range Adjustment: The detector allows for adjustment of the detection range to suit the specific installation environment. Refer to the internal dip switches or potentiometers for precise settings.
- Sensitivity Control: Adjust the sensitivity to prevent false alarms from small animals or environmental factors while maintaining effective human detection.
- Walk Test: Perform a walk test to verify the detection area and ensure the detector triggers reliably within the desired zone.
5. Operation
5.1 Detection Principles
The Optex BX-80NR utilizes dual PIR technology to create a precise horizontal barrier. It detects changes in infrared energy (body heat) within its field of view. For an alarm to be triggered, an object must pass through both the upper and lower detection beams, significantly reducing false alarms caused by small animals or environmental disturbances.
5.2 Status Indicators
The detector may feature an LED indicator to provide status feedback:
- Red LED (Solid): Indicates detection.
- Red LED (Flashing): Low battery warning.
- Green LED (Solid): Power on / Normal operation (may vary by model revision).
Refer to the specific wiring diagram or internal labels for detailed LED behavior if available on your unit.
6. Maintenance
Regular maintenance ensures the long-term reliability and performance of your BX-80NR detector.
6.1 Cleaning
- Periodically clean the sensor lens with a soft, dry cloth to remove dust, dirt, or spiderwebs that could obstruct the detection beams.
- Do not use abrasive cleaners or solvents, as these can damage the plastic housing or lens.
6.2 Battery Replacement
When the low battery indicator flashes, replace the battery promptly to ensure continuous operation.
- Carefully open the detector housing.
- Remove the old CR2 lithium battery.
- Insert a new 3V CR2 lithium battery, ensuring correct polarity.
- Securely close the detector housing.
- Test the detector to confirm proper function after battery replacement.
