4. Configuración e instalación
4.1 Consideraciones de montaje
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.
- Asegúrese de que la superficie de montaje sea estable y segura.

4.2 Encendido del dispositivo
The BX-80NR is battery-powered. It requires a 3V CR2 lithium battery (not included). Ensure correct polarity when inserting the battery.
- Abra la tapa del compartimiento de la batería.
- Insert the CR2 lithium battery, observing the polarity markings (+/-).
- Cierre bien la tapa del compartimento de la batería.
4.3 Ajustes y configuraciones iniciales
After mounting and powering the device, perform initial adjustments to optimize detection performance.
- Ajuste del rango de detección: 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.
- Control de sensibilidad: Adjust the sensitivity to prevent false alarms from small animals or environmental factors while maintaining effective human detection.
- Prueba de caminata: Perform a walk test to verify the detection area and ensure the detector triggers reliably within the desired zone.
5. Operación
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 Indicadores de estado
The detector may feature an LED indicator to provide status feedback:
- LED rojo (fijo): Indicates detection.
- LED rojo (intermitente): Advertencia de batería baja.
- LED verde (fijo): 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. Mantenimiento
Regular maintenance ensures the long-term reliability and performance of your BX-80NR detector.
6.1 Limpieza
- Limpie periódicamente la lente del sensor con un paño suave y seco para eliminar el polvo, la suciedad o las arañas.webs that could obstruct the detection beams.
- Do not use abrasive cleaners or solvents, as these can damage the plastic housing or lens.
6.2 Reemplazo de batería
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.
