Bouyer GXT 4000-16 Configuration guide

1 DESCRIPTION
The GXT 4000 microphone console is a touch screen console. It has from 16 up to 64 programmable soft
keys for making PA broadcasts into selected areas or zones. It is designed to operate over a bus architecture,
meaning that several consoles can be used over the same network, while collectively occupying just one single
audio channel. In fact, the consoles are self-regulating, with audio channel priority always being given to the first
console that picks up the channel. The main part of the console may be flush fitted or mounted on its own swivel
base for tabletop use.
The GXT 4000 console comes complete with:
• an electret microphone,
• a touch screen for setting and selecting zones,
• a memory card reader for broadcasting pre-recorded messages,
• a loudspeaker for monitoring announcements, etc.,
• a fail soft switch with protective hood.
It may be used to:
• view the degree of occupancy of the network’s zones,
• broadcast an announcement into one or more zones.

Recess mounting
Recess dimensions: 240 x 150 mm
Separate the central unit from its base by extracting the 2 screws and brackets located underneath the unit.
Use the brackets to fix the unit to a supporting surface that has a depth of between 1 and 35 mm.
For greater depths, use spacers, wedges or longer bracket retaining screws.
Warning: when recessing, the power supply jack socket will only be accessible if the thickness of the mounting
surface is 25 mm or less. Should the recess depth exceed this, the console should be powered using the
RJ45 sockets.
4.1 General Data –Operational Limits
Number of consoles
The number of consoles that can be connected to the same bus depends on the type of installation used.
Power
A single power supply can be used to power several GXT 4000 consoles.
The table below gives an indication of power delivery limitations according to the number of consoles and
distances between them.
Number of
consoles
Distance between the power supply source and
the farthest console

100 m
1
150 m max.
Data calculated using the optional power supply NS110557 (24 V d.c., 500 mA) and a cable impedance of
0.085 ohm.m-1. In order to work, the absolute minimum voltage arriving at the power input terminals of each
console must be 12 V with maximum load applied.
Cabling
Consoles on the same bus are daisy-chained together at the RJ45 inputs/outputs using the cables supplied.
Over long distances, an EL720 connector box may be necessary. For audio and RS485, twisted pairs are
recommended. Electrical interference (audio parasites) may be minimised by screening the audio connectors.
Following these guidelines, the total cable length can reach 1000 m all buses combined (the limit normally
associated with RS485 networks where no repeaters are used).

Fail soft mode:
To wire up the fail soft, connect the connection box (PGM) to the 26 pin connector strip located inside the
console. The connector strip may be accessed by removing the cover on the console’s base.
There is one configuration switch per protected pushbutton located on the main board inside the console; use
these switches to set the contacts to NO (normally open) or NC (normally closed) as required.
For each of the four optional pushbuttons, the indicator lamp is driven by zeroing the associated control point.

5 APPLICATION
5.1 Use with a CS 2500 Central Monitoring Unit as a public safety announcement system
When connected to a CS 2500 central monitoring unit, the GXT 4000 can be used to broadcast safety
announcements within selected zones; its in-built touch screen does away with any need for separate switch
matrices, thus keeping costs and cabling to a minimum. Other PA sources such as piped music, etc., may be
connected either to the CS 2500’s AUX input or to the 0 dB inputs of CS 2003 audio matrices.
IMPORTANT: Ensure that the CS 2500’s software version is version V4.50 or greater.

6.2 Normal operation
Keys 1 to 64 (according to the actual configuration) and the General Announcement key are keys that can be
programmed for:
• selecting zones (depending on how the CC 3816, DN 3816 or CS 2500 is programmed),
• selecting groups of zones (depending on how the CC 3816, DN 3816 or CS 2500 is programmed),
• broadcasting messages.
The Cancel key may be used to cancel the current selection.

the function is active
A zone or zones may be picked up by pressing one or several programmed keys. The request is then sent to
the host system which switches the zones and then sends the state of the respective keys back to the console.
Where:
• the zone is free or occupied by a lower priority source, the zone will be assigned to the console;
• a console on the same bus has picked up the zones, the other consoles on that bus are unable to switch
zones and the message Audio bus unavailable is displayed if this attempts to issue a request.
Once one or more zones have been assigned to the console, then:
• a simple microphone announcement may be broadcast:
➢ in non-latching mode by holding down (indicator comes on permanently) to activate the
microphone and broadcast a spoken announcement within the selected zones. Releasing the key stops
the broadcast and the indicator goes out,
➢ in latching mode by pressing key once (causing the indicator to come on) to activate the
microphone and broadcast a spoken announcement within the selected zones, until the same key is
pressed a second time to switch off the microphone and extinguish the indicator;
• a chime followed by a microphone announcement may be broadcast:
➢ in non-latching mode by holding down (the indicator comes on permanently) to activate the preset
chime. When the chime finishes the chime indicator goes out and the microphone indicator lights to show
a spoken announcement can now be made in the selected zones up until the key is released (andthe
indicator extinguishes),
➢ in latching mode by pressing key once (indicator lights) to activate the preset chime. When the
chime finishes the chime indicator goes out and the microphone indicator lights to show a spoken
announcement can now be made in the selected zones up until either of the two keys is pressed once
more to switch off the microphone (and extinguish the indicator);
In all the above cases, releasing the key or pressing it a second time will interrupt the sequence.
• a message stored on the memory card may be broadcast:
➢ pressing opens the Broadcast message window and causes the indicator to come on
permanently. This screen is used to select one of the messages on the memory card, broadcast it by
pressing Play , stop it by pressing Stop and exit by pressing .
The progress bar shows how far through the announcement the playback is.
Where a key’s program combines the selection of one or more zones and the broadcasting of a message, the
console first cancels the assignment of any zones it has assigned, issues a request to switch the zones programmed
into the soft key and, if the request is accepted, broadcasts the configured message .
