SDC 928 Series Access Control Panel

Capable of supporting up to 480 users, the 928 Series Integrated Digital Keypad from SDC has four independent outputs with four independent timers which on correct PIN entry releases an electric door lock and grants access. The EEPROM memory retains all entry codes and programming during a power failure. An anti-passback feature prevents use of the same code twice before a programmed time period elapses. Other notable characteristics include audible code entry verification, two LED status indicators, anti-tailgate and keypad tamper lockout.
