Call stations
The call stations are used mainly for announcements, but are also used for manual control of
the PAVIRO system. Possible call station functions include zone/group selection,
announcements, program allocation, triggering chime and alarm signals, and message
playback. However, special commands such as volume control, light control, function displays,
and much more are also possible. The call stations can therefore also be configured for
general control tasks. If an announcement is to be routed through a loudspeaker zone that is
already occupied, the system issues an occupied notification (i.e., the talk button indicator
light flashes). If the call station concerned has a higher priority, it can interrupt the lower-
priority call from the other call station/signals. The system is configured to indicate the
conditions: The user is notified that the system is occupied when selecting the zone/group
(before the interruption) by the flashing talk button indicator light. The user can now decide
whether to interrupt the signal immediately, or whether to wait until the end of the active
announcement. Each zone selection key has two indicator lights: A green indicator light shows
the current selection, and a red indicator light shows if the zone is occupied with an
emergency signal. System information or error messages can be displayed on the call station's
illuminated graphic display.
Control inputs and outputs
The PAVIRO system has analog and logic control inputs and logic control outputs. The control
inputs allow a connection to be established to fire alarm systems, intruder alarm systems, or a
control desk. However, it is also possible to connect external switches, controllers, or rotary
potentiometers, or triggers from external equipment (power supply, power amplifiers, and so
on). The control outputs allow the user to activate/deactivate external devices, trigger signals
and events, remotely control doors, gates, and roller blinds, and much more.
Automatic control
The controller contains a quartz-controlled real-time clock that can be switched to DCF77
radio clock operation via an optional antenna. The system clock automatically recognizes leap
years; in DCF77 mode, it also automatically switches to daylight-saving time. Up to 80 external
slave clocks (max. 1 A) can be controlled by the system clock. A special output for polarity
switching pulse, which is protected against short circuits, is integrated in the controller for
this purpose. Slave clocks are automatically adjusted if a time difference between the slave
clocks and the system clock is detected, for example after a power failure or in the event of
manual input. Together with the calendar function, the system clock can be used to execute
functions such as a break chime, music, gate control, light control, and so on. These functions
can be programmed for specific days, but can also be implemented on an hourly, daily,
weekly, monthly, and annual basis. Up to 500 time-controlled events can be entered.
Functions and parameters can be connected in an internal sequence. The TaskEngine in the
controller GUI provides a graphic way to combine processes individually. One example would
be a chime signal to be transmitted at a certain volume and with a specific priority in specific
call groups, and which simultaneously activates a control output. In this case, the process
consists of the “chime” and “analog output” function blocks combined with the parameters of
chime type, volume, priority number, call group number, as well as the type and number of the
control output. The processes can be triggered via special function keys on the call stations or
via control inputs, but can also be linked to clock or calendar dates.
Interfaces
In addition to the control inputs and outputs, the PAVIRO system also includes other
interfaces:
–
The call stations are connected to the controller via the CST bus (CAN bus standard). Up
to four call stations can be connected via one CST bus.
