SDC’s EntryCheck™ 923 series narrow indoor/outdoor 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.

923P models add HID proximity reader capability to the keypad and 923PW models are designed to interface with SDC’s IPPro® and most access control systems providing a standard 26-bit Wiegand output.
