Description
SDC FB-4 relay modules are control boards designed to ensure compatibility between access control hardware components and power supplies. These modules simplify system installation and troubleshooting by allowing different configurations to be specified for a single power supply, making them ideal for installers managing multi-door security systems.
The FB-4 is compatible with SDC power supplies and access control systems. Installation requires basic electrical knowledge; our authorized dealer experts at E.D. Locks can provide detailed guidance on module selection and wiring.
