1. Introduction
Thank You for purchasing Tannoy CMS50 ICT Ceiling Monitor System.
The Tannoy CMS50 ICT Ceiling Monitor System is suited for high level music and
speech reinforcement applications requiring exceptional sonic quality with
uncompromised reliability. Achieving fast, simple and cost effective installation in new
and existing buildings, this versatile design has addressed the two most common
failures of background music and sound reinforcement systems, which are firstly the
tweeter, and secondly the crossover. With the revolutionary design of the ICT™ drive
unit, neither of the above criteria applies, assuring you years of trouble free use.
ICT™ or Inductive Coupling Technology utilises a wireless electromagnetic tweeter
that does not require a crossover and cannot be burned out from heavy or abusive
use. The 1” aluminium high frequency dome has a deep drawn skirt which sits on the
inside of the low frequency voice coil in the same magnetic gap. The skirt is like a
single shorted turn, which is induced with high frequency information generated by the
low frequency voice coil, which is fed a full bandwidth signal. The ICT™ dome is at the
heart of our 5” ceiling transducer which utilises a moulded plastic cone and nitryl
rubber surround to further enhance it’s durability and long term reliability.
The ICT driver is housed in a rugged aluminium ceiling enclosure that has been
optimally tuned to achieve maximum bass response and tonal balance.
The CMS50T ICT houses a Tannoy THP 30 multi-tap transformer for distributed-line
operation. The transformer provides high system sensitivity, a wide bandwidth and
dynamic range, with very low insertion loss. For critical Applications provision has
been made for the CMS50T ICT to accept the THP 60, a 60W multi-tap transformer.
2. Unpacking
Every Tannoy CMS50 ICT and accessory is carefully inspected before packing. After
unpacking, please inspect your CMS50 ICT to make sure no damage has occurred in

3.2. Connections
The CMS50 ICT is provided with a pluggable European type connector, which is
located on the back of the speaker can, under the wiring cover as shown in Figure 3a
below. This consists of a plug and socket. The plug can be removed from the socket
(Figure 3b) for wiring.
Figure 3a Figure 3b
To cable is inserted into the hole on the side of the plug, and the screw is tightened to
secure the cable in the plug. The plug is wired to the amplifier such that the
connections are as follows:
Pin 1 is Positive -connect to Red
Pin 2 is Negative -connect to Black
For additional speakers, pin 3 and 4 are in parallel with pins 1 and 2, where:
Pin 3 is Positive
Pin 4 is Negative
Before connecting the speaker, ensure the wiring cover and cable clamp on the back
of the can are open as shown in Figure 3c. Connect the wired plug into the socket.

The CMS50 ICT is supplied as a complete product, ready for installation. An optional
C Ring, Tile Bridge and Plaster Ring are available if required. The CMS50 ICT has
been designed for ease of installation.
To install the speaker, connect the speaker as described in the section 3.2. The
speaker has 3 tags (Figure 3f) which hold the speaker in place. Ensure these tags are
flat against the can before installing into the ceiling.
Figure 3f
Slide the speaker through the 210mm hole, as shown in figure 3i, and tighten the
outer screws on the front baffle. Tighten these screws until a secure grip is
