The unit operates without hardwired power, making it suitable for locations where running electrical conduit is impractical or cost-prohibitive. It delivers a detection range of 200 feet outdoors and 400 feet indoors, projecting an invisible infrared beam between a transmitter and receiver. When the beam is broken, the detector signals an alarm condition. Licensed security installers and integrators are the primary trades working with this device.\u003c\/p\u003e\n\u003cp\u003eThe SL-200TNRI is suited for both residential and commercial perimeter protection. Outdoor installations typically include driveways, fence lines, gate entries, and open yard zones where a buried loop or passive motion sensor would not provide adequate coverage. Indoor use cases include warehouses, large retail spaces, and long corridor monitoring. The battery-powered design expands placement flexibility along property boundaries or in structures without accessible power runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e200-foot outdoor detection range and 400-foot indoor detection range\u003c\/li\u003e\n  \u003cli\u003eBattery-powered operation eliminates the need for hardwired electrical supply at the mounting location\u003c\/li\u003e\n  \u003cli\u003eInfrared photobeam technology provides a defined, linear detection zone\u003c\/li\u003e\n  \u003cli\u003eSuitable for both indoor and outdoor deployment in perimeter security layouts\u003c\/li\u003e\n  \u003cli\u003eSingle-unit quantity per package for straightforward procurement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style photobeam detector for use in perimeter security and access control systems requiring a battery-powered infrared beam sensor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed security systems technician or low-voltage alarm installer. The transmitter and receiver must be mounted on opposing surfaces with a clear, unobstructed line of sight aligned to the specified beam axis. Before servicing or repositioning an installed unit, confirm the alarm panel is placed in test mode to prevent false dispatch. Consult local low-voltage and alarm system codes for mounting height requirements and tamper-protection provisions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDetection Range (Outdoor)\u003c\/strong\u003e: 200 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDetection Range (Indoor)\u003c\/strong\u003e: 400 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Source\u003c\/strong\u003e: Battery\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Photo Beams\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\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: SL-200TNRI\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OPTEX","offers":[{"title":"Default Title","offer_id":51688309850418,"sku":"SL-200TNRI","price":1808.03,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/optex-sl-200tnri-battery-powered-photobeam-detector","provider":"Voomi Supply","version":"1.0","type":"link"}
