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,
•a stylus.
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
3 100 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.

GXT 4000
Installation: Refer to the GXT 4000 Operator Manual The CS 2500 has 3 separate audio buses:
•audio bus GX1 (GX 2500 Control/Audio 1 RJ45 socket) to which can be connected either a
GX 2500 or one or more GXT 4000 or GX 3016 units (address 1);
•audio bus GX2 (GX 2500 Control/Audio 2 RJ45 socket) to which can be connected either a
GX 2500 or one or more GXT 4000 or GX 3016 units (address 2);
•audio bus AUX (AUX XLR socket) to which can be connected either a 0 dB source or one or
more GXT 4000 or GX 3016 units (address 3).
The maximum number of GXT 4000 units that are capable of being connected to a network may be
calculated as follows:
No. of GXT 4000 ≤ 50 - No. of CS 2500 – No. of CS 2003 – No. of GX 2500 – No. of GX 3016
5.2 Use with a CC 3816
The CC 3816 matrix has two special inputs for connecting two GXT 4000 or GX 3016 console buses
together.
Installation: Refer to the GXT 4000 Operator Manual
The CC 3816 has 2 separate audio buses:
•audio bus 1 (Console 1 RJ45 socket) to which can be connected one or more GXT 4000 or
GX 3016 units (address 1);
•audio bus 2 (Console 2 RJ45 socket) to which can be connected one or more GXT 4000 or
GX 3016 units (address 2).
Refer to the CC 3816 Manual for additional information.
5.3 Use with the DN 3816 (multi-DN application)
