Curtain PIR detectors create a flat, narrow detection zone rather than a wide volumetric field, making them well-suited for doorways, windows, hallways, and perimeter entry points where targeted coverage is required. The AP2-20N detects heat signatures from moving individuals passing through the defined detection plane and signals an alarm or access-control panel upon activation. Licensed security installers and low-voltage technicians are the typical trade professionals who specify and install this type of sensor.\u003c\/p\u003e\n\u003cp\u003eThe AP2-20N is intended for indoor ceiling-mount deployments where a curtain-style detection zone is needed to monitor a specific corridor or entry point. Typical applications include retail storefronts, office entryways, stairwells, and interior doorframes where a full volumetric detector would generate unwanted coverage overlap. The ceiling-mount form factor allows the sensor to project the curtain zone downward across a defined passage, providing reliable presence detection without covering adjacent areas.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCurtain detection pattern provides a narrow, focused zone ideal for doorway and perimeter monitoring\u003c\/li\u003e\n  \u003cli\u003eCeiling-mount design allows downward projection of the detection curtain across passages\u003c\/li\u003e\n  \u003cli\u003ePassive infrared sensing technology detects body-heat signatures of moving persons\u003c\/li\u003e\n  \u003cli\u003eIndoor-rated construction suitable for climate-controlled commercial and residential environments\u003c\/li\u003e\n  \u003cli\u003eSold individually as a single unit for flexible deployment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style ceiling-mount curtain PIR sensor compatible with standard security alarm and access-control panel inputs that accept passive infrared detector wiring.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed low-voltage or alarm technician in accordance with applicable local electrical codes and NFPA 72 guidelines. De-energize the security panel and associated wiring circuits before connecting or disconnecting sensor leads. Ceiling height and mounting angle will determine the width and floor-level coverage of the curtain zone, so consult the manufacturer documentation for recommended mounting parameters. Do not install in outdoor or high-humidity environments, as this unit is rated for indoor use only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDetection Type\u003c\/strong\u003e: Passive Infrared (PIR) Curtain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Style\u003c\/strong\u003e: Indoor Ceiling Mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each (1 unit per package)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OPTEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AP2-20N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OPTEX","offers":[{"title":"Default Title","offer_id":51688891089202,"sku":"AP2-20N","price":151.35,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/optex-ap2-20n-indoor-curtain-pir-detector","provider":"Voomi Supply","version":"1.0","type":"link"}
