The HID GLOBAL CORPORATION 20NKS-00-004FGR is the Signo 20 smart card reader, a compact access control reader designed for credential-based entry systems. Finished in black and silver, this unit reads standard card profile credentials and is suited for commercial and light industrial access control installations. The Signo 20 supports pigtail wiring connections and is sold individually as a single unit. Security integrators and low-voltage electricians are the primary installers for this device.
The Signo 20 is intended for use in commercial access control deployments where standard card profile credentials are required. Its black and silver finish suits modern door hardware aesthetics in office, facility, and institutional environments. The pigtail connection style accommodates direct field wiring to access control panels without requiring a separate connector adapter.
Designed as an OEM-style replacement or new-install reader for commercial access control systems that support standard card profile smart credentials.
Installation should be performed by a licensed low-voltage electrician or qualified security systems integrator. Power down the access control panel before making wiring connections. Follow NEC low-voltage wiring requirements and the panel manufacturer's wiring diagram when terminating the pigtail leads. Verify credential compatibility with the installed access control system before commissioning.
