Safety Notices

Some regional construction codes require the use of a secondary method of securing loudspeakers in the ceiling to provide security of a backup 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.
The CMS 603 ICT LS is UL-1480, category UUMW, for use with non-DC supervised systems.
Electrical Safety Notice: To comply with the standard UL-1480, metal-clad flexible conduit (BX) is required for connection to the terminal block for proper
earth grounding.
In order to comply with UL regulations, the PI backcan must always be used with the CMS PI models.
SAFETY NOTE:
In order to comply with the relevant fire safety regulations (ie. 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; b) use of terminal blocks of a lower melting point but protected with thermal insulation;c) use of terminal blocks such that, on melting, an
open-circuit or a short-circuit does not occur.
