Bosch LC1-WM06E8 User Manual
Bosch has also developed the Simulated Acoustical
Feedback Exposure (SAFE) test to demonstrate that
they can withstand two times their rated power for
short durations.
This ensures extra reliability under extreme conditions,
leading to higher customer satisfaction, longer
operating life, and much less chance of failure or
performance deterioration. All plastic parts are self
extinguishing according to UL 94 V0.

Installation/configuration notes
Installation
The LC1 Modular Ceiling Loudspeaker range is very
installation friendly. The loudspeaker consists of a
frame with the loudspeaker driver and metal or ABS
grille with integrated light conductor, matching
transformer and ceramic screw terminal connection
block. On the loudspeaker are provisions for mounting
the optional pilot-tone indication board and optional
line/loudspeaker surveillance board.
Power tapping on the 70 V / 100 V matching
transformer allows selection of full-power, half-power,
quarter-power and eight-power radiation.

Ordering information
Due to the modular concept of this system, it is
important to order not only the ceiling loudspeaker
LC1‑xMxxE, but also the flush ceiling mounting
accessory of your choice, as mentioned here below.
The loudspeakers can be flush mounted into the
ceiling by means of the “U” shaped Metal Mounting
support bracket LC1‑MMSB or the ABS Ceiling
Mounting ring LC1‑CMR with optional Back Box
LC1‑CBB.
In order to take full advantage of the modular
architecture, all parts are separately packaged in the
order in which they are required for installation.

LC1-MMSB Mounting Support Bracket
The metal Mounting Support Bracket has two ceiling
clamps, which are secured with thumb screws in the
ceiling hole. The bracket is also provided with two 4
mm holes for mounting the bracket with two screws
into thin (metal) ceilings. Two spring catchers (for
accepting the V-shaped loudspeaker springs) are
provided. The bracket provides a provision for
attaching an optional safety steel cord.

LC1-CMR Mounting Ring
The LC1‑CMR is an alternative for the ceiling mounting
support bracket. The ABS Mounting Ring has two
screw driving clamps to fix the mounting ring into the
ceiling board. Inside the ring, two spring catchers (for
accepting the V-shaped loudspeaker springs) are
provided.

LC1-CBB Back Box
On top of the mounting ring, provisions are present to
“click-on” the optional Back Box. The combination of
Mounting Ring and Back Box prevents sound traveling
via the ceiling cavity to adjacent areas, and fully
protects the loudspeaker from dust, falling objects.
The Back Box has knock‑out holes for two grommets
(11 mm/0.80 in) and for two cable glands (20.5 mm/
0.80 in)
