## Summary description

SATEL AP-20NB is an indoor passive infrared (PIR) curtain detector designed to create a narrow detection zone for precise motion monitoring. The AP-20NB produces a curtain-like beam pattern to protect windows, doorways or passageways with reduced false alarms. Compact and wall-mountable, it connects to alarm systems to trigger alerts when motion crosses the defined curtain area.

## Long description

SATEL AP-20NB is an indoor passive infrared (PIR) curtain detector designed to create a narrow, curtain-like detection zone suitable for precise motion monitoring. The compact wall-mountable sensor concentrates its field of view into a slim plane to monitor specific entry points such as windows, doorways and corridors. The detector connects to alarm systems and provides a focused motion trigger while helping reduce false alarms from general room activity.
Advantages
The narrow-beam design provides targeted detection along a slim plane, allowing protection of openings without monitoring the entire room. Compact housing simplifies mounting on walls or frames with minimal visual impact. The PIR technology delivers reliable motion sensing while maintaining low power demand. The focused coverage reduces false triggers from unrelated movement and supports integration with standard alarm control panels.
Suitable for
 Protecting windows and sliding doors with a narrow detection curtain
 Monitoring doorways and internal passageways
 Adding targeted coverage where full-room motion detectors are unsuitable
 Integration into burglary alarm systems for perimeter or interior protection
Key specifications
 Detection principle: passive infrared (PIR)
 Detection pattern: narrow, curtain-like beam
 Installation: wall mount
 Intended environment: indoor use
 Typical applications: window, doorway and passageway monitoring
How to use
Install the detector on a stable vertical surface aligned so the curtain beam crosses the protected opening at the desired height. Connect the detector to the alarm control panel following the panel manufacturer's wiring and configuration instructions. Adjust orientation and height during commissioning to ensure the narrow detection plane covers the target area while avoiding nearby heat sources or moving objects that could cause false alarms. Test the sensor coverage and control-panel response after installation.
Usage recommendations
For consistent performance, mount the detector away from direct sunlight, HVAC vents and heating sources. Use the narrow-beam detector as a complement to area motion sensors to create layered protection: curtain coverage for openings and broader detectors for general room monitoring. Regular functional tests during maintenance checks will help verify correct alignment and reliable alarm operation.
