The HID GLOBAL CORPORATION 20TKS-T3-00056M is the Signo 20 smart card reader, a compact access control reader designed for terminal-mount installations. Finished in a black and silver housing, this unit reads smart credentials and communicates with access control panels in commercial and light industrial security systems. It is installed by low-voltage security and access control technicians as part of a door or entry point access infrastructure. The Signo 20 is sold as a single unit and is designed for straightforward integration into existing wired access control architectures.
This reader is suited for commercial access control deployments where a terminal-mount form factor is required. It is used at controlled entry points such as doors, gates, and secure areas within office buildings, data centers, and similar facilities. The black and silver finish is appropriate for modern interior and exterior mounting locations. Installation typically occurs alongside electronic door hardware and an access control panel or controller.
Designed as an OEM-style replacement and standard installation component for commercial smart card access control systems that accept terminal-mount readers.
Installation should be performed by a licensed low-voltage technician familiar with access control wiring practices. Disconnect power to the access control panel and any door hardware before beginning wiring. Follow applicable local codes and the panel manufacturer wiring guidelines when connecting the reader. Do not apply power to the reader until all terminal connections are secured and verified.
