3 Unpacking
Every Tannoy product is carefully inspected before
shipment. After unpacking, please inspect your
product to ensure no damage has occurred in
transit. In the unlikely event of damage, please
notify your dealer and retain all shipping materials
as your dealer may require return shipment. All
CMS loudspeakers are shipped in pairs and
provided with the following accessories as
standard: C-ring, tile-bridge kit, cut-out template
and paint mask. A plaster (mud) ring is available
as an optional accessory.
4 InstallationinSuspended Ceilings
1. Remove the ceiling tile from its frame and place
it on a at surface. Position the cutout template
(self-adhesive backed) on the tile. (Fig.1)
2. Cut out the hole in the ceiling tile using a pad
saw following the broken line indicated on
the template.
3. Place the C-Ring and tile-bridge on top of the
ceiling panel, aligning the C-Ring over the hole,
and screw the C-Ring to the tile bridge using the
xings provided. (Fig.2)
1 Introduction
This Quick Start Guide (QSG) provides the basic
information required to install and connect the
blind-mount (BM) versions of Tannoy CMS Series
in-ceiling loudspeakers.
For additional information, including product
technology, photo identication of product features,
dimensional drawings, and complete technical
specications, please refer to the full CMS Series
Operation Manual.
For installation of CMS Series pre-install (PI) versions,
please refer to either the CMS PI Quick Start Guide
or the full CMS Operation Manual.
2 Safety Notices
Some regional construction codes require the use
of a secondary method of securing loudspeakers in
ceiling to provide security of a back-up support.
A secondary support line should be attached
from the safety loop on the rear of the product to
a source point on the ceiling. For PI models, the
secondary support line should be attached from
the back of the driver chassis to a source point on
the ceiling. Please consult the relevant construction
codes in your region.
When using a power driver to install the product, it
is essential to use the correct torque level settings
to avoid over tightening and damage to the ceiling
material or clamps. Recommended torque setting:
1.5 Nm. Tannoy will not be held responsible for any
damages caused by the improper installation of
these loudspeakers.
Electrical Safety Notice: to comply with the
standard UL1480, metal-clad exible conduit (BX)
is required for connection to the terminal block for
proper earth grounding.
SAFETY NOTE: In order to comply with the
relevant re safety regulations (i.e. BS 5839:1998),
it is required that in the event of re, that failure of
the circuit to which the loudspeaker is connected
does not occur before evacuation of the building
is complete. Suitable measures include:
•Use of terminal blocks (for connection to primary)
with a melting point of not less than 650°C, for
example constructed from ceramic materials;
•Use of terminal blocks of a lower melting point
but protected with thermal insulation;
•Use of terminal blocks such that, on melting, an
open-circuit or a short-circuit does not occur.

2. Cut out the hole in the ceiling using a pad saw
following the broken line indicated on the
template. Slide the C-ring into the ceiling,
aligning it over the cut-out hole. (Fig. 2)
3. Follow steps 4 through 6 in section 4 above.
6 Installation of Optional
Plaster Ring
The optional plaster (mud) ring is designed
for pre-installation into newly constructed,
non-suspended ceilings.
1. Nail or screw the plaster ring to the joists.
(Fig. 1)
2. Lay the speaker wiring to where the speaker
will be tted. Complete the plastering work on
the ceiling.
3. Follow steps 4 through 6 in Section 4 above.
4. Go to Section 7 following for instructions on
wiring and set-up instructions.
5. Slide the speaker assembly through the hole.
Turn the screws (denoted “Screw Fix”) clockwise
on the front of the speaker to extend the
mounting wings. Tighten the screws until a rm
grip is achieved.(NOTE: Screws have a PoziDriv
head; use of a PoziDriv driver is recommended).
If using a power driver, Tannoy recommends a
torque setting of 1.5 Nm. (Fig.2)
DO NOT OVERTIGHTEN!
6. Attach the nylon safety to the hooks on the front
bae before attaching the grille by presenting it
to the speakers and allowing the magnets to pull
it into position.
NOTE ON INSTALLATION OF CMS 403DCe:
Before tightening the screws in step 5, swivel the
speaker in the desired direction. When the screws
are tightened, the speaker will lock into position.

1. Position the cutout template (self-adhesive
backed) on the ceiling. (Fig. 1)

7 Wiring and Setting Up
1. Open the wiring cover (if applicable) and locate
the Euro-type connector plug and socket at the
back of the speaker. (Fig.1)
2. For connection to an amplier, use Pins 1 and 2
(Fig.2)
3. Close the wiring cover and tighten both screws
on the cable clamp (if applicable).
4. Use the rotary switch on the front of the unit
to select low impedance (LoZ) mode or high
impedance (70 V or 100 V) for distributed
applications.
The speaker is supplied in low impedance
mode. Never connect the speaker to a
70 / 100 volt amplier while it is set for
low impedance.
CMS 403ICT models and CMS 503ICT models (all
variants) use a 30 W transformer. In distributed line
applications, the transformer can be tapped at
30 W, 15 W and 7.5 W, with an additional 3.75 W
tap for 70 V line systems.
CMS 603ICT models (all variants) use a 60 W
transformer. In distributed line applications, the
transformer can be tapped at 60 W, 30 W and
15 W with an additional 7.5 W tap for 70 V
line systems.
