The EntryCheck 921P Indoor Outdoor Keypad is a surface-mount digital keyless entry system designed for access control applications. SDC’s 921P models are indoor/outdoor standalone digital keypads with proximity reader and controller (two-piece configuration), designed to control access of a single entry point with up to 500 users. Each user is assigned a proximity card and/or a personal identification number (PIN). Presentation of a proximity card or keypad entry of a code activates one or both of the output relays which releases an electric door lock.
