Output module (relay, 8) PCO2002-A1
The 'Output module (relay, 8)' PCO2002-A1 extends the number of digital outputs for each
audio matrix by additional 8 electrically isolated relay outputs.
Each relay offers 2-pole changeover contacts. All contacts, NC, NO and center are routed to
terminals.
Further 8 relay outputs can be added by connecting an 'Output extension (relay, 8)'
PCO2003-A1 module directly to this module.
It was specifically developed for use with all digital audio matrices PC200x-A1, the 'Voice
alarm panel Compact 400' PC1001-A3 and the 'Voice alarm panel Compact 1000' PC1002-
A3.
The connection between the PCO2002-A1 and the audio matrix is established via the
'PACE-Bus' (RS485).
Output extension (relay, 8) PCO2003-A1
The 'Output extension (relay, 8)' PCO2003-A1 extends the number of digital outputs for each
audio matrix by additional 8 electrically isolated relay outputs.
Each relay offers 2-pole changeover contacts. All contacts, NC, NO and center are routed to
terminals.
One PCO2003-A1 connects to a PCIO2002-A1 or a PCO2002-A1 via an attached flat band
cable.
Automatic volume control
The 'Automatic Volume Control' (AVC) function is used to supervise the ambient noise of an
area and increase the volume of the speaker line in case that the ambient noise is higher
than the predefined value, such as on train stations, in airports and in shopping malls.
The AVC function is required as a way of adjusting the sound level of the audio signal to suit
the current situation in the event of huge fluctuations in background noise. This ensures that
the wanted signal is always louder than any background noise so that it will be possible to
understand what is being said and on the other hand, announcements will not be too loud for
people in quiet buildings.
Automated volume control module PCA2008-A1
The 'Automated volume control module' PCA2008-A1 receives the audio level of the
measuring microphones PCA2007-A1. The PCA2008-A1 uses the received audio levels to
calculate the average, which is then forwarded to the connected audio matrix for further
processing. The input sensitivity can be set to line level or microphone level.
It is possible to connect up to four PCA2007-A1 to one PCA2008-A1. The connected
microphone wiring is monitored for short-circuits, interruptions and earth faults. Inactive lines
can be excluded via jumper. A fault is reported with the fault indication relay.
The PCA2008-A1 was specifically developed for use with the digital audio matrices PC2001-
A1, PC2003-A1, PC2005-A1, as well as the 'Voice alarm panel Compact 400' PC1001-A3
and the 'Voice alarm panel Compact 1000' PC1002-A3.
Automated volume control microphone PCA2007-A1
The AVC microphone PCA2007-A1 is a measuring microphone that was specifically
developed for use with the digital audio matrices PC2001-A1, PC2003-A1, PC2005-A1, as
well as the 'Voice alarm panel Compact 400' PC1001-A3 and the 'Voice alarm panel
Compact 1000' PC1002-A3. It constantly records the levels in the surrounding area within a
set frequency range and transmits the value to the receiver assembly PCA2008-A1 for
further processing.
The output level can be set to line level or microphone level.
