Quick Start Guide

1 Introduction

This Quick Start Guide (QSG) provides the basic
information required to install and connect the pre­install (PI) 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 blind-mount
versions, please refer to either the CMS BM 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.

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 Installation in Suspended Ceilings

An optional pre-install backcan is available for all
pre-install (PI) models. The backcan is designed
for pre-installation in newly constructed, non­suspended ceilings.

NOTE: The CMS 603ICT models have the
transformer pre-attached to the inside of the
backcan; the CMS 503ICT models have the
transformer pre-attached to the loudspeaker
assembly.

1. Attach the backcan to a secure xing point.

This can be done one of three ways:

METHOD 1: Fix to a secure point using suitable
xings attached to the four xing holes on the PI

backcan. (Fig.1)

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.

METHOD 2: Fix to a secure point using suitable
xings and the exible straps attached to the PI

backcan. (Fig. 2)
