UNCTIONALITIES OF
PR821-CH
CONTROLLER
Many functionalities of PR821-CH controller and PRxx1 series controllers are identical. This manual
mainly describes functionalities which are distinctive for PR821-CH controller and are not included in
the manual Functional description of PRxx1 series controllers. 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.
6.1 Input functions
PR821-CH controller is equipped with three inputs and XM-2 expander can be connected to the
controller in order to increase the number of available inputs by two. Input lines can be configured
in regard of their function and NC/NO triggering by means of PR Master software within properties
of particular controller. For NO line (normally open), the triggering is done by closing the circuit
while in case of NC line (normally close), the triggering is done by opening the circuit (voltage
disconnection).
Additionally all input functions can be divided into ON/OFF monitored and ON monitored. In case of
ON/OFF monitored input functions, controller detects the moment of input activation and
deactivation. In case of ON monitored input functions, controller detects only their activation, thus
it is not relevant how long the input is activated and when it is deactivated as only the activation
triggers certain actions within the system. For example
[01]:Door contact
function is ON/OFF
monitored type and the controller reacts to its activation and deactivation while the function
[31]:Set AIR CONDITION
is ON monitored one and the controller reacts only to its activation.
Table 3 contains selected input functions of PR821-CH controller and remaining ones are described
in the manual Functional description of PRxx1 series controllers.
