Optex AP-20NBR(C) Indoor Recessed Curtain Pir Sensor

Product Description

The OPTEX AP-20NBR(C) is an indoor recessed-mount curtain passive infrared (PIR) motion sensor designed for wall installation in commercial and residential security and building-automation applications. A curtain PIR creates a flat, fan-shaped detection zone rather than a wide volumetric pattern, making it well suited for doorways, windows, and defined entry corridors where precise zone coverage is required. Licensed security installers and low-voltage technicians are the primary trade professionals who specify and install this device.

The AP-20NBR(C) is intended for indoor wall-mount applications where a recessed installation profile is preferred for aesthetic or tamper-reduction reasons. Typical scenarios include retail entryways, office corridors, and residential doorways where a curtain detection pattern provides reliable occupancy or intrusion sensing without triggering from activity outside the defined zone.

Key Features

• Curtain PIR detection pattern for precise, narrow-zone coverage at doorways and entry points
• Recessed wall-mount design provides a low-profile installation with reduced tamper exposure
• Designed for indoor environments including commercial and residential settings
• Passive infrared technology — no RF emissions, no active transmitter required

Compatibility

Designed as an OEM-style indoor recessed curtain PIR sensor compatible with standard low-voltage security and access-control panel wiring configurations. No specific compatible panel model numbers were provided in the product data.

Installation Notes

Installation should be performed by a licensed low-voltage or security systems technician in accordance with local electrical codes and the authority having jurisdiction. Power down or disarm the security panel before wiring the sensor to avoid false alarms or panel faults. Follow the manufacturer datasheet for mounting height, detection angle orientation, and terminal wiring — do not exceed the panel auxiliary power rating when adding sensors to a zone. Verify the curtain pattern alignment after installation by performing a walk-test before closing the wall cavity.
