Dynacord CPA 2000, Owner'S Manual

Page: 29 / 58

The CPA 2000 electro acoustics compact system can be set internally for the operation with prioritized
microphones / microphone terminals. When shipped it is factory preset to cascade priority operation.
Changing the priority programming is performed on the printed board assembly 83107 using the jumpers
J 301 to J 308 (also refer to diagram 4). Therefore you have to disconnect the appliance from the mains
supply as well as from the battery supply and detach the cover.
For how to adjust the different setting options, please refer to the following table:
Jumper Notes Inserted Open
J301 Priority operation
Pure mixing operation, i. e. MIC 1 - 3 and
AUX signals are mixed. During an
outgoing voice message, the inputs 1 - 3
and the AUX input are switched off.
When the priority inputs 1, 2, or 3 are
active, the AUX signal is muted, no
obligatory reception (standard setting).
Operation of MT 2005 is not possible
J302
Block priority, i. e. a running message of any
input is finished without interruption. Gong,
alarm and voice messages still possess the
higher priority
Cascade priority, i. e. higher priority
inputs mute lower priority inputs. MT
2005 paging stations possess always
block priority amongst each other! Priority
in sequence: voice message, alert, gong,
input 1, input 2, input 3, AUX (standard
setting)
J303
The pre-gong signal is deactivated, even when
the alert, gong extension kit is installed.
Prior to any voice message coming from
MIC 1, MIC 2, MIC 3 or from a
microphone terminal MT 2005, a
pre-gong signal is released
(standard setting).
J304
The signal of the input 1 has a higher priority
than gong, alert, or any other voice message, i.
e. it is possible to make an announcement
during an outgoing alarm.
Normal priority sequence
(standard setting)
J305
Mixing mode for MIC 2 and MIC 3, despite the
selected priority. Activating the priority inputs 2
or 3 mutes the AUX signals (No obligatory
reception). Operation of MT 2005 paging
stations is not possible.
Normal priority sequence
(standard setting)
J306
J301 is inserted (priority operation). Mixing
mode for MIC 3, despite the selected priority.
Activating the control input Prio 3 mutes the
AUX signal, no obligatory reception. Most
beneficial in combination with the
voice-operated switch 90170 with switchable
microphone.
Norm al priority sequence
(standard setting)
J307/308
Paging station surveillance; if a microphone
terminal does not answer the fault-relay drops
out (see also “REMOTE CONTROL [58]
connector).
J307 = paging station 1
J308 = paging station 1 + 2
J307 and J308 = paging station 1 +2 +3
(The surveillance mode is only attainable in
this order!)
No surveillance of paging stations
(standard setting)
