5.2PROANNOUNCE – DPC 4000 Paging Consoles

5.2.1 System Overview

The PROANNOUNCE 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

￿analog circuitry surveillance via integrated pilot tone generator

￿processor surveillance via watchdog function

￿line surveillance via pilot tone and 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 while a switchable pilot tone generator monitors the audio section. Additionally, the internal supply voltage is constantly measured. When it falls below a critical threshold an alert message is being displayed. 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 PROANNOUNCE 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.
