SDC UR2-4 UR Series Universal Microprocessor-Based Door Controller, Relays

Deliver centralized, reliable access control across multi-door installations with the Security Door Controls UR2-4 door controller. This microprocessor-based controller brings programmable logic to the panel level, reducing the need for separate relays and cutting wiring complexity so your installers spend less time on-site and your maintenance team spends less time troubleshooting. The UR2-4 supports 2 stations and offers 6 selectable output modes, with (2) fused SPDT and (2) SPDT outputs plus two inputs per station and four auxiliary inputs to connect locks, monitoring contacts, door stations and peripheral devices. Its compact footprint (4.5" W x 5" H x 0.9" D) makes it easy to mount in control cabinets or retrofit into existing infrastructure. Ideal for commercial, education and healthcare facilities, the UR2-4 enhances security and surveillance integration while providing robust monitoring and access control capabilities. Add the UR2-4 to your security system to simplify installations, lower component costs and improve uptime—contact our sales team to configure or order today.
