System overview
This chapter explains the basic features of the PAVIRO system and its most important
functions.
General overview
The PVA-4CR12 is the controller of the PAVIRO system. The controller contains all necessary
audio functions and is responsible for controlling and monitoring the complete PAVIRO
system. The type and number of connected audio sources, amplifiers, and relays are extremely
variable, and can be adjusted to individual requirements. A single controller can manage up to
16 call stations and up to 492 loudspeaker zones. Control inputs and outputs can be used for
controlling and monitoring functions. Both logic level and the analog level signals can be
processed. Configuration is performed on a PC using the IRIS-Net software, which also
provides access to system documentation and the required user interface. A configuration can
be changed at any time, and adjusted to new circumstances without having to modify the
system installation. A PC is required only for loading or changing the configuration; it does not
need to be connected during live operation. In many cases, however, a permanently connected
PC is helpful; for example, to provide detailed status displays and log reports, real-time
loudspeaker and sound control, or for remote diagnosis and maintenance via the network. The
user interface can be individually tailored, and up to 32 password levels can be assigned.
Audio routing
A digital audio matrix is integrated into the controller. Up to 8 local audio inputs, 2 message
playback channels, and 4 internal generators are available. The 4 audio output channels are
connected to the amplifiers via a 4-channel audio bus. The amplifiers include an audio input
router where the correct input signal is selected automatically. Each loudspeaker circuit can
be connected with amplifier outputs via a relay matrix, which allows for 492 loudspeaker
zones. The controller manages the audio signals, and distributes them according to priority. In
addition to the call stations, other audio sources can also be connected to the audio inputs
such as microphones, mixing desks, CD players, MP3 players, tuners, and so on. A number of
different connections are available for optimum adjustment.
Audio processing
The controller provides separate volume controls with a mute function for each audio input
and audio output. Each audio input has a 3-band equalizer and a compressor for optimal
sound adjustment of the audio sources. All outputs are fitted with a 5-band equalizer and a
limiter. For the equalizers, the operator can select from five different filter types for each band
filter (peak, low-shelving, high-shelving, high pass, low pass). Volume levels, filter parameters,
and so on are set on the PC during configuration. However, these can also be changed in realtime during operation using the graphical user interface, the special keys for the call stations,
or external operating controls.
Signal generators
The controller provides four signal generators: Two independent generators for generating
alarm signals and two independent generators for generating chime signals. Operators can
choose between 24 alarm types and six chime types that are available ex-works.
Message manager
The integrated message manager is for EVAC messages and alarm signals, as well as
commercial messages and chime/pre-chime signals. The message manager allows easy
configuration of EVAC and commercial messages, and other customized audio signals by using
the IRIS-Net software.

Operation manual 08-May-2017 | 04 | F01U306900
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 lowerpriority 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.

08-May-2017 | 04 | F01U306900 Operation manual
– The power amplifiers and the routers are controlled and monitored by the controller via
an additional, independent CAN bus interface.
– The connection to a PC is established via an Ethernet interface.
– An optional OM-1 Module can be installed at the rear of the device.
The OM‑1 is a compact interface module which is prepared for a connection to an OMNEO
network. It can send and receive Dante audio to and from up to four other PAVIRO controllers
with an OM‑1 Interface Module.
Monitoring
The controller monitors all internal functions itself, and the connected call stations, routers
and power amplifiers including their connection lines are also monitored by polling and pilot
tone. Loudspeaker lines can be monitored by impedance measurement or end-of-line modules
installed at the last speaker. The PAVIRO system also supports emergency power operation –
in the event of a power failure, the controller can assume all power management functions,
that is, all unnecessary internal and external consumers switch to standby mode, or are
deactivated and only reactivated again when required. This greatly reduces power
consumption, and ensures maximum operating time on battery power. Error messages can be
displayed on the call station displays in plain text. The status of the “combined fault” is
available via the floating READY contact on the controller.
