SAFETY NOTE:

In order to comply with relevant fire safety regulations (i.e. BS 5839:1998), it is required that in the event of fire,
that failure of the circuit to which the loudspeaker is connected does not occur before evacuation of the building is
complete. Suitable measures include: ­ a) use of terminal blocks (for connection to primary) with a melting point of not less than 650°C, for example
constructed from ceramic materials;
c) use of terminal blocks of a lower melting point but protected with thermal insulation;
d) use of terminal blocks such that, on melting, an open-circuit or a short-circuit does not occur.

1. INTRODUCTION

Thank you for purchasing this Tannoy Ceiling Monitor System product. This product range is suited
for music and speech reinforcement applications requiring exceptional sonic quality with uncompromised
reliability.

2. UNPACKING

Every Tannoy product and accessory is carefully inspected before packing. After unpacking, please
inspect your product to make sure no damage has occurred in transit. In the unlikely event of any
damage, would you please notify your dealer immediately and retain your shipping carton, as your

3. 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. 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: 1.5Nm

Tannoy will not be held responsible for any damages caused by the improper installation of these
loudspeakers.

4. ALTERNATIVE INSTALLATION APPLICATIONS

The Tannoy CMS401 DCe and CMS401e speakers are primarily designed for in-ceiling applications.
However, the versatile design allows for installation into other applications such as boardroom tables
and museum display kiosks. The thickness of the installation surface must be between 1mm and
20mm. It is your responsibility to ensure that the installation surface is strong enough to support the
weight of the speaker. Please contact Tannoy customer services if you require further advice.

7.1 MECHANICAL INSTALLATION GUIDE FOR SUSPENDED CEILINGS

Slide the tile panel back into the suspended ceiling. The tile bridge ends will catch over
the railings, supporting the weight of the speaker.

5

Slide the speaker assembly through the hole and turn the screws on the front of the
speaker to extend the black mounting wings. Tighten the screws until a firm grip is
achieved.

4

DO NOT OVERTIGHTEN!

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 fixings provided.

3

Cut out the hole in the ceiling tile using a circular saw or pad saw.

2

Remove the ceiling tile from its frame and place it on a flat surface. Mark the
cut-out area on the ceiling tile by tracing around the template provided.

1

7.2 MECHANICAL INSTALLATION GUIDE FOR SHEET-ROCK (PLASTER BOARD) CEILINGS

Slide the speaker assembly through the hole then swivel the speaker to point in the
desired direction.

Tighten the black mounting wing screws until a firm grip is achieved. If using a power
driver, Tannoy recommends a torque setting of 1.5Nm.

DO NOT OVERTIGHTEN!

NOTE: When the screws are tightened the speaker will lock into position.

4

Go to section 6 for wiring and set-up instructions then return to point 4 below.

3

Cut out the hole in the ceiling using a circular saw or pad saw, then slide the
C-ring into the ceiling, aligning it over the cut-out hole).

8. WIRING AND SETTING UP:

Locate the euro socket at the back of the product.

1

For connection to an amplifier, use pins 1 and 2:

• Pin 1 is positive

• Pin 2 is negative

For connection to additional speakers in a distributed line,
pins 3 and 4 are in parallel where:

• Pin 3 is negative

• Pin 4 is positive

2

Use the rotary switch located on the front of the unit to select whether you wish to use
the speaker in a low-impedance or distributed-line application.

3

THE SPEAKER IS SUPPLIED IN LOW IMPEDANCE MODE. NEVER CONNECT THE
SPEAKER TO A 70/100 VOLT AMPLIFIER WHILE IT IS SET FOR LOW IMPEDANCE.

All CMS401e and CMS401 DCe models use a 30W transformer. When using distributed­line systems, the transformer can be tapped at 30W, 15W and 7.5W, with an additional

3.75W tapping for 70.7V line systems.

Slide the speaker assembly through the hole then swivel the speaker to point in the
desired direction.

Tighten the black mounting wing screws until a firm grip is achieved. If using a power
driver, Tannoy recommends a torque setting of 1.5Nm.

DO NOT OVERTIGHTEN!

NOTE: When the screws are tightened the speaker will lock into position.

11. PAINTING

If desired, the grille and baffle panel may be painted to match the surrounding décor.

Painting the baffle:

Carefully mask off the driver assembly using the paint-mask provided to ensure that the paint does not come into
contact with the cone and roll surround.

Painting the grille:

Carefully remove the acoustically transparent foam from the reverse side of the grille.
Paint the grille and then replace the foam.
Re-bond the foam to the grille over the entire area using a light spray-adhesive to avoid audible resonances.

Painting the trim:

The speaker must be aimed before painting.
The rubber trim should be left in place while painting.
Apply a vinyl emulsion to the trim.
