Bosch LC1-WM06E8 User Manual

This ABS Surface Mounting Box is available for
securing the ceiling loudspeaker to walls or hard
ceilings. The Surface Mounting Box has at the side two
holes standard covered opposite positioned and four
knock‑out holes on the rear side. For optional single
point suspension of the assembly of Ceiling
Loudspeaker and Surface Mounting Box, a separate
metal suspension kit, LC1‑MSK is available.

This kit contains a tri‑angled metal plate to be
attached by three screws (supplied) onto the rear of
the Surface Mounting Box and includes three
suspension chains, converged in an eye‑hook.

Ease of installation for individual loudspeaker and
loudspeaker/fire-dome combinations. The Fire Dome
mounting is fixed in the ceiling, prior to the ceiling

speaker mounting. The Fire Dome has a dual
connection entry, enabling loop‑through cabling and
provision for attaching an optional safety steel cord.
Connections are made using an innovative ceramic
screw terminal connection block on the metal fire
dome with loop-through facility.
Suitable for use in air‑handling spaces.

The loudspeakers have provision for optional mounting
of the Pilot‑tone Indication Board. This small PCB with
LED can fixed into a holder, connected to a light
conductor standard fitted. The presence of the
pilot‑tone can be visually checked by means of the
flashing of the LED, integrated in the front grille rim.
The required level of the pilot tone signal is 4 V rms @
20 kHz and the load to the amplifier from these boards
is negligible.
