It provides a flexible interface between access control panels, fire alarm systems, and electromagnetic or electromechanical locking hardware. The UR-1 serves as a signal-switching component that converts low-voltage control signals into relay-switched outputs, allowing a single control panel to operate multiple door devices or trigger auxiliary functions. Licensed security and low-voltage technicians are the primary installers for this type of device.\u003c\/p\u003e\n\u003cp\u003eThe UR-1 is suited for commercial and light-industrial door control applications where a relay-based interface is needed to coordinate door holders, magnetic locks, electric strikes, or alarm outputs. It is commonly installed in access control retrofits, new construction security buildouts, and fire-alarm door-release integrations. The board mounts inside a control enclosure or alongside access hardware at the door head or frame.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUniversal relay board design allows flexible integration with a wide range of door control hardware\u003c\/li\u003e\n  \u003cli\u003eProvides relay-switched output for low-voltage door access and locking devices\u003c\/li\u003e\n  \u003cli\u003eSupports integration with fire alarm and access control panels\u003c\/li\u003e\n  \u003cli\u003eCompact single-unit form factor suitable for enclosure mounting\u003c\/li\u003e\n  \u003cli\u003eSold individually as a direct replacement or system expansion component\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style relay interface board for use in commercial electronic door access control and locking systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of relay boards in access control systems should be performed by a licensed low-voltage or security systems technician in accordance with applicable local codes and NEC Article 725. Disconnect and de-energize all power to the access control panel and connected locking hardware before servicing or replacing the relay board. Verify relay output ratings match the load requirements of connected door hardware before energizing the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Door Closers \/ Holders \/ Alarms\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: SDC Security Door Controls\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UR-1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SDC","offers":[{"title":"Default Title","offer_id":51687510573362,"sku":"UR-1","price":192.45,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/sdc-security-door-controls-ur-1-universal-relay-board","provider":"Voomi Supply","version":"1.0","type":"link"}
