5.2 PROMATRIX – DPC 4000 Paging Consoles
5.2.1 System Overview
The PROMATRIX system includes 5 different models of DPC 4000 Series paging stations and one paging station
extension. All microphone terminals employ gooseneck microphones, 6 or 8 function keys and a covered alarm
key. An additional alarm key and a key-locked switch can be retrofitted. The paging stations are available with 10,
20, 30, or 50 selection keys. All models also employ LC-displays (2 lines with 16 characters each).
The following list provides you with an overview of available paging station models:
DPC 4106 6 function keys
DPC 4510 8 function keys + 10 selection keys + alarm key
DPC 4520 8 function keys + 20 selection keys + alarm key
DPC 4530 8 function keys + 30 selection keys + alarm key
DPC 4550 8 function keys + 50 selection keys + alarm key
DPC 4350 paging console extension with 50 selection keys
All paging consoles include the following common features:
• all functions are processor-controlled
• configuration data is stored in non-volatile FLASH RAM
• condenser microphone with pre-amplifier and compressor / limiter circuitry
• freely programmable key-assignment
• easy key-labeling through label-strips and MS WORD™ templates
• processor surveillance via watchdog function
• line surveillance via polling functions
• covered alarm key (not with DPC 4106)
• additional alarm keys or key-locked switches can be optionally retrofitted
• connection of an external PTT-microphone or audio source
• piezo buzzer for acoustical alerts
• an optional loudspeaker can be retrofitted
• setup-mode allows direct parameter setting at the paging station
• two-line LC-display
All paging consoles are processor-controlled and extensive monitoring functions are provided. The watchdog
function monitors the processor system. The line surveillance function recognizes any line-interruption and/or
short-circuits in the audio and RS-485 control cabling. Upon the detection of failure a corresponding message is
displayed.
The PROMATRIX Designer software allows comfortably configuring the paging stations. Its graphic, dialogue-
oriented user interface offers effortless assign of key functions, priorities, options, and many other paging station
functions.
Note: Up to four paging consoles can be connected to a single input of the central unit. However, it
is important to keep the fact in mind that in case of line interruption and short-circuit several
microphone terminals may fail. Despite, one input allows only launching one message at a
time. All other connected paging stations are presented with a busy-message. If these
restrictions are not acceptable, every microphone terminal – or at least all directing stations
and other important paging stations – should have its own input at the central unit.
