DRC232C Dual Reader Controller

DRC232C is designed to control 2 access points. The DRC’s 2 card reader input ports can accept input from most reader technologies, analog alarm devices, and analog request to exit devices. The DRC is equipped to control 4 output relays (2 door relays + 2 auxiliary relays). In the event of a computer or communication failure, it will continue to operate and log history transactions into the memory buffer. Expanding beyond 2 doors is simple and inexpensive with the system; up to 16 DRC panels can be linked together using a secondary RS-485 network.
