Authenticate cardholders, mobile credential users and keypad users at a controlled opening with the HID Global Signo 40 access control reader. The reader supports Wiegand output for connection to compatible access-control panels and presents status through a red LED, flashing green LED indication and an integrated buzzer. Its black and silver finish suits installations where the reader remains visible at a door, vestibule or secured interior opening. This configuration combines keypad entry with standard card-profile support, BLE mobile access capability and NFC mobile credential capability. It also supports card serial number processing and an EM 32-bit format. These credential and interface options let an installer align the reader with an existing controller and the credential technologies deployed at the site, without requiring the reader to be treated as a standalone access-control system. Part number 40TKS-00-00022V identifies the Signo 40 terminal configuration with its specified indicator behavior: red LED operation, flashing green indication, buzzer feedback and surface operation enabled. The keypad distinguishes this configuration for openings where a PIN can be required alongside a credential. Use it at employee entrances, restricted offices and other doors that need local visual and audible response during credential presentation.
