CMS PI SERIES
Introduction
This Quick Start Guide (QSG) provides the basic information required to install and connect the pre-install (PI) versions of Tannoy CMS
Series in-ceiling loudspeakers. For additional information, including product technology, photo identification of poduct features,
dimensional drawings, and complete technical specifications, 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.

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 flexible conduit (BX) is required for connection to the
terminal block for proper earth grounding.
Safety Note: In order to comply with the 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:
• •
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.
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.
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, non-suspended ceilings.
Note: The CMS 603 and 803 models have the transformer pre-attached to the inside of the backcan; the CMS 503 models have the
transformer pre-attached to the loudspeaker assembly.
Step 1
Attach the backcan to a secure fixing point. This can be done one of three ways:
Method 1:
Fix to a secure point using suitable fixings attached to the four fixing holes on the
PI backcan. (Fig.1)
Method 2:
Fix to a secure point using suitable fixings and the flexible straps attached
to the PI backcan. (Fig. 2)
Method 3:
a. Attach the PI backcan to the optional pre-mount plaster ring using the fixing
points povided with the pre-mount ring. (Fig 3)
b. Secure the wings of the pre-mount ring to a secure fixing point using
suitable fixings.
