SDC 923 Series EntryCheck™ Indoor/Outdoor Narrow Digital Keypads
Reliable Access Control for Narrow Door Frames and Mullion Applications
The SDC EntryCheck™ 923 Series Narrow Digital Keypads provide secure, convenient access control for commercial, industrial, and institutional facilities.

Featuring a narrow-profile, weather-resistant, and vandal-resistant housing, the 923 Series is ideal for mullion mounting, narrow door frames, and other space-constrained entry points. The illuminated 12-key keypad, tactile buttons, dual LED status indicators, and built-in tamper switch provide dependable operation and convenient user feedback.
Available models include standalone keypad access, integrated HID proximity card reader capability, and Wiegand output for integration with compatible access control systems.
