SR3 Overview
The UniKey SR3 (Product Number SR3-UK-0001) is a 125kHz Prox and Bluetooth Low Energy all-
in-one commercial reader for access control systems. The reader can retrofit legacy PACS
systems using proximity, otherwise known as prox and easily implement optional features such
as Touch-To-Open® and Inside/Outside Intelligence™ for an enhanced user experience at the
door. The reader is both cost-effective and easy to install, without requiring any rewiring or
paneling.
The SR3 is intended to be used in conjunction with an access controller as part of the access
control system to provide secure access to buildings or areas. The reader is installed and
communicates an access request to the controller using the standard Weigand protocol. This
request is made by the end user presenting either prox card or fobs using ASK or FSK
modulated Wiegand formats; the user can also use a Bluetooth enabled device storing mobile
credentials powered by UniKey mobile application.
