3 I NTRODUCTION
3.1 Designed Function
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.
Note: If programmed from PC the PR311 requires RACS 4.2 or higher.

Add-on features when operating in the Integrated Access Control System (with Host device)
256 access groups
32 time schedules for access level control
Time schedules for Identification Mode and Door Mode
128 time periods per schedule
Events recorded by Host (CPR32SE Host controller or PC with PR Master program in online mode)
3.3 Operation in the Integrated Access System
In this case the PR311 is a part of an Integrated Access Control System (IACS) which operate under control of
the Host device. The Host device adds some extra functionality to entire access system. When the PR311
operates in the IACS users can be divided into 256 access groups, each group may have different access
authorization controlled by a time schedule. The PR311 allows up to 32 time schedules which are used to
control access and two special schedules – one of them controls the Identification Mode while the other controls
the Door Mode. Events which occur in the IACS are stored by Host device. If the communication with the Host
is broken the PR311 continues operation with time schedule settings which existed when communication
disappeared. After communication with the Host resumes all clock related settings (e.g. time schedules) are
refreshed and updated.
