2 System Overview
The T2004 Multi-Control Head system allows the use of between one and
five control heads with a single T2020 or T2040 radio. The control heads
are configured as one Primary and up to four Secondary. The Primary
control head is the only one which controls the radio’s power, as well as
power to each Secondary control head, otherwise the functionality of all the
control heads is the same. Advantages: radio to control head length able to
be greater than the standard 6m cable.
The Multi-Control Head system consists of two kits, designed to connect to
your existing Series II T2020 or T2040 radio and T2008 power supply:
■the T2004-A20 (T2020) or the T2004-A40 (T2040) Primary Multi-
Control Head Kit (one required per system).
■the T2004-A21 (T2020) or T2004-A41 (T2040) Secondary Multi-
Control Head Kit (not required if only one control head is used in the
system).
The T2004-A20 or T2004-A40 Primary Head Kit provides the Primary
control head as well as the Radio Interface PCB. This PCB is housed inside
a dummy (Clayton’s) control head and replaces the standard control head on
the radio. The radio can be concealed if required, as all radio controls are
now done via the Primary control head.
The T2004-A21 or T2004-A41 Secondary Head Kit provides one
Secondary control head and other equipment needed to install the control
head for use with the radio.

14 System Overview T2004 Multi-Control Head System Manual
© Tait Electronics Limited May 2004
Each control head can be installed anywhere on a multi-drop line up to
2000m long (not included), and is powered locally by a mains-operated DC
plug pack. A speaker plugs into each control head to provide local Tx and
Rx audio.
Note The DC Plug pack is not supplied as part of the kit. The correct
plug pack for each country can be ordered separately as per the
table on page 18.
The control heads provide the same functionality as the standard T2000
control head, but will not provide for a DTMF module to be fitted. In
addition, the control heads provide some extra functions:
■Global Mute
The Global Mute function is provided to avoid the possibility of
audio feedback when two or more control heads are placed in close
proximity. This function is individually selectable on each control
head, via a link JP1 on the control head PCB. Refer to Part B, Con-
trol Head for further information.
■Power Switch Selection
The Power Switch Selection function is provided so that only one
control head in the system (the Primary control head) is able to con-
trol the system’s power. This function is selectable by the fitting of a
jumper (JP2) on the control head PCB of the Primary control head.
Refer to Part B, Control Head for further information.

2.4 System Connections
Each control head connects to the system network via the Micromatch to
RJ45 Cable, which plugs into the RJ45 Wallbox. The RJ45 Wall boxes are
fitted at intervals along a multi-drop cable.
The radio also connects to the system network via the Micromatch to RJ45
Cable, which plugs into the X2AM01 Multi-Head Radio Interface. The
other end of the cable plugs into an RJ45 Wallbox, which is fitted at one
end of the multi-drop cable. See system diagram earlier for block overview
of system.
