The PR311 access controller has been designed for use in access control installations or systems as an outdoor access control device to enable user identification via EM 125 kHz UNIQUE standard proximity cards and/or PINs. The PR311 unit can operate stand-alone or as a part of integrated (networked) access control system. When controller operate as a stand-alone unit it independently (i.e. autonomously) controls the supervised door access point. In this mode controller doesn't offer either event recording or time schedules (time tables). Programming of a unit can be done locally using its keypad and programming cards or remotely from PC. The connection to PC requires UT-2 programming interface and programming software (e.g. PR Master or PR Master Lt). The PR Master is used to administrate the Integrated Access Control System which consist of PRxx1 and PRxx2 access controllers (from Roger), the PR Master Lt is a reduced version the PR Master and is dedicated only for configuration of a single controller unit. If controller is a part of the Integrated Access Control System which is managed by the Host device the PR311 extends its functionality and enables definition of user access groups, time schedules and recording of events. The PR311 can be configured for operation with external XM-2 I/O Extension Module and external PRT series reader. The use of XM-2 adds two NO/NC type inputs and two relay outputs to the controller. The system setup utilizing an XM-2 module provides higher level of security for door access control system by separating its logical element (the controller unit) from the actuator element controlling the door lock (i.e. the door lock relay). The use of external PRT reader enables two-way door control.
