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.

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
