SDC’s 918 series of indoor standalone digital keypads are designed to control access of a single entry point for facilities with up to 500 users. Each user is assigned a personal identification number (PIN). Keypad entry of a valid one to six digit code activates one or both of the output relays which releases an electric door lock.

918W models are designed to interface with SDC’s IPPro® or most access control systems, providing a standard 26-bit wiegand output.
