DEVICE DESCRIPTIONS

12Microphone

After pressing the TALK button and after the BUSY LED lights making announcements in pre-selected areas or groups is possible using the integrated gooseneck microphone. The optimum distance from the microphone is approximately 20 to 35 cm. The microphone pre-amplifier embodies a limiter to control signal peaks and protect the system against overdrive.

The extension socket (EXT) allows connecting a second microphone with TALK button. Assigning the function (area, group) of the external microphone is performed during the configuration via PC.

13Display

Depending on the actual operational status of the system, the LC-display with 2 lines of 16 characters each, shows information on time, operation mode, user notes, setting up, fault messages including precise device / module specification, etc.

This is the interface for connecting DPC 4000 Series paging stations to the PROANNOUNCE system. The 8- pole RJ-45 connector provides power supply, control interface RS-485, and audio connections. The microphone terminal has to be connected to a corresponding RJ-45 wall outlet using the supplied connection cord (3 m). The following figure shows the pin-assignment of LAN socket and RJ-45 network cable. Please also pay attention to chapter 5.2.14 Cable Lengths.

2EXT socket

Mostly, this socket is used for connecting a DPC4350 paging station extension. Use the supplied network cable (0.5 m) to connect the DPC4350 to the paging console’s EXT socket.

In case no paging station extension is being connected, utilizing the EXT socket for connecting a second microphone with TALK button or other external audio signal sources to the paging console is possible as well. Detailed information is provided in chapter 5.2.13 Optionally Available Accessories.
