ESCRIPTION AND SPECIFICATION
PR821-CH is single room/door controller used in RACS 4 access control system and it additionally
offers hotel automation and intruder alarm functionalities. PR821-CH is equipped with card holder
and built-in two system EM125kHz/MIFARE® reader. Peripheral devices communicating in RACS
CLK/DTA format such as HRT82MF hall reader, function key panel HRT82FK and XM-2 I/O expander
can be connected to the controller.
Controllers can be configured with PR Master software installed on computer and they can be
connected to computer by means of communication interface e.g. UT-2USB, UT-4DR, RUD-1 or by
means of CPR32-NET network controller.
Note: PR821-CH controllers require PR Master 4.5.14 or newer.
