SDC UR-1 UR Series Universal Microprocessor-Based Door Controller, Relays

Deliver reliable, flexible door control and monitoring with the Security Door Controls UR-1 universal microprocessor-based door controller. Built for integrators and facilities teams, the UR-1 relay module simplifies access control and security system design by offering field-programmable, DIP-switch selectable relay modes that can operate as dry contacts or voltage (wet) outputs to match virtually any locking device.

The UR-1 reduces installation complexity through centralized wiring and on-board logic, decreasing the need for additional communicating contacts or standalone relays—cutting labor and making troubleshooting faster. Its compact 3.2" (W) x 2" (L) x 1" (H) footprint fits neatly into crowded control panels while delivering robust monitoring and lock control for access control, door monitoring and broader security or surveillance integrations.

Ideal for retrofit projects, multi-door systems, and professional security installations, the Security Door Controls UR-1 relay module provides a cost-effective, dependable solution for managing locks and monitoring door status. Add the UR-1 to your next access control deployment or contact our sales team to discuss integration into your security system.
