Contact closure receivers of this type are used in security, access control, and building automation systems where isolated dry contact signals must be extended over fiber optic links. The FDC8RM1 accepts signals from a paired fiber transmitter and restores them as discrete contact outputs at the receiving end. Licensed security integrators, low-voltage technicians, and systems installers work with this class of equipment in both new construction and retrofit applications.\u003c\/p\u003e\u003cp\u003eThe FDC8RM1 is suited for installations requiring transmission of contact closure signals across electrically noisy environments or where ground loop isolation is needed. Typical applications include alarm panels, door and gate control systems, relay outputs, and PLC input interfaces. The 1mm plastic optical fiber interface makes it compatible with short-to-medium distance fiber runs commonly used in commercial and light industrial installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8 independent contact closure receive channels on a single unit\u003c\/li\u003e\n\u003cli\u003e1mm plastic optical fiber interface for signal reception\u003c\/li\u003e\n\u003cli\u003eProvides electrical isolation between transmit and receive ends\u003c\/li\u003e\n\u003cli\u003eSuited for dry contact signal extension in security and automation systems\u003c\/li\u003e\n\u003cli\u003eSold individually as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style receiver for use with compatible 8-channel contact closure fiber transmitters in security, access control, and building automation fiber optic systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed low-voltage or security systems technician familiar with fiber optic signal equipment. De-energize all connected control panels and associated equipment before connecting or disconnecting fiber or contact wiring. Handle 1mm plastic optical fiber terminations with care to avoid contamination of the fiber end face, which can degrade signal quality. Refer to local codes and the paired transmitter documentation for proper system configuration.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannels\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 (Rx)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiber Type\u003c\/strong\u003e: 1mm Plastic Optical Fiber\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: FDC8RM1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COMNET","offers":[{"title":"Default Title","offer_id":51557409554738,"sku":"FDC8RM1","price":2226.25,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/comnet-fdc8rm1-8-channel-contact-closure-receiver","provider":"Voomi Supply","version":"1.0","type":"link"}
