The curtain lens reshapes the detection pattern of the sensor, narrowing the field of view into a thin vertical plane rather than a wide coverage zone. This makes it well-suited for protecting specific openings such as doorways or windows without triggering on broader room activity. Licensed alarm installation technicians and low-voltage security contractors are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThe BV-L3 curtain lens is intended for use with compatible DSC PIR motion detector housings where the standard wide-angle lens is swapped out for a curtain-style pattern. Curtain lens configurations are commonly specified in residential and light commercial intrusion detection systems when the installation requires targeted zone coverage. This lens ships as a single unit and installs directly into the sensor housing without additional hardware in most applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCurtain detection pattern narrows PIR coverage to a focused vertical zone\u003c\/li\u003e\n\u003cli\u003eDesigned as a direct replacement lens for compatible DSC PIR detectors\u003c\/li\u003e\n\u003cli\u003eAllows targeted protection of doorways, windows, or other defined openings\u003c\/li\u003e\n\u003cli\u003eSingle-unit packaging simplifies replacement inventory management\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement curtain lens for compatible DSC PIR motion detector housings.

Disconnect power and disarm the security system before opening the detector housing or handling the lens. Handle the lens carefully to avoid contamination of the optical surface, which can degrade detection performance. Re-test detector coverage pattern after lens replacement to confirm proper zone definition.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: PIR Lenses\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DSC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BV-L3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DSC","offers":[{"title":"Default Title","offer_id":51688293564722,"sku":"BV-L3","price":21.43,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/dsc-bv-l3-pir-curtain-lens-security-sensor","provider":"Voomi Supply","version":"1.0","type":"link"}
