It is part of a fiber-based signal transport system used in security, access control, and industrial automation installations. The unit accepts a single-mode fiber input and restores the original contact closure states at the receiving end, maintaining signal integrity over long transmission distances. Licensed security integrators and low-voltage technicians are the primary installers of this device.\u003c\/p\u003e\u003cp\u003eThe FDC8RS1 is suited for applications where multiple contact closure signals must be transported across a fiber backbone, including perimeter security systems, gate control, alarm panels, and building automation networks. It is used in both commercial and institutional facilities where copper-based signal runs are impractical due to distance, electrical noise, or ground loop concerns. Single-mode fiber transport allows deployment over extended cable runs typical of campus and multi-building environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8 independent contact closure channels on a single receiver unit\u003c\/li\u003e\n\u003cli\u003eSingle-mode fiber input for long-distance signal transport\u003c\/li\u003e\n\u003cli\u003eRestores dry contact closure states at the receive end with high fidelity\u003c\/li\u003e\n\u003cli\u003eSuitable for security, access control, and industrial automation applications\u003c\/li\u003e\n\u003cli\u003eCompact form factor appropriate for rack, wall, or enclosure mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style receiver for use within fiber-based contact closure transport systems requiring single-mode fiber connectivity and 8-channel capacity.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed low-voltage technician or security systems integrator familiar with fiber optic termination and contact closure wiring practices. De-energize all associated control panels and signal sources before making connections. Follow local codes and manufacturer guidelines for fiber handling, minimum bend radius, and connector cleanliness. Verify transmitter and receiver fiber type compatibility before commissioning the link.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Channels\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Type\u003c\/strong\u003e: Contact Closure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDevice Role\u003c\/strong\u003e: Receiver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiber Type\u003c\/strong\u003e: Single-Mode\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: COMNET\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FDC8RS1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COMNET","offers":[{"title":"Default Title","offer_id":51687101169970,"sku":"FDC8RS1","price":2885.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66ba83b81a581c2fe9ef4df3988802f8.jpg?v=1788231311","url":"https:\/\/voomisupply.com\/products\/comnet-fdc8rs1-8-channel-contact-closure-receiver","provider":"Voomi Supply","version":"1.0","type":"link"}
