u Excellent speech and music reproduction
u Easy installation with one grille size and one
complete set of accessories
u Choice of different ceiling mounting methods
The LC1 Modular Ceiling Loudspeaker range can be
used for a wide variety of ceiling environments. They
provide excellent speech and music in indoor public
address applications. The range offers a choice of five
loudspeakers distinguished by input power, opening
angle and sound reproduction.
It includes three 6 W single cone loudspeakers offering
a choice of opening angle and two high performance
12 W and 24 W coaxial loudspeaker drivers. They all
have the same grille size and can be used in
combination with the same mounting accessories.
The loudspeakers are suitable for use in air‑handling
spaces when installed with the LC1‑MFD enclosure.
The loudspeaker frame includes provision for
mounting the optional pilot-tone indication board or
WLS board and has standard a light conductor to
indicate the pilot-tone status.

Functions
Voice Alarm applications
Voice alarm loudspeakers are specifically designed for
use in buildings where system performance for verbal
evacuation announcements is governed by regulations.
The LC1 Modular Ceiling Loudspeaker range is
designed for use in voice alarm systems and is
EN 54‑24 certified and compliant with British standard
BS 5839‑8.
Protection
The loudspeakers have built-in protection to ensure
that fire damage to the loudspeakers does not cause
failure of the connected circuit. In this way system
integrity is maintained, ensuring loudspeakers in other
areas can still be used to inform people of the
situation.
The loudspeakers can also be used in combination
with a metal fire-dome to increase protection of the
cable termination.
Connections
The loudspeakers have a ceramic screw-terminal
connection block, thermal fuse and heat-resistant,
high-temperature wiring.
Certifications and approvals
All Bosch loudspeakers are designed to withstand
operating at their rated power for 100 hours in
accordance with IEC 268‑5 Power Handling Capacity
(PHC) standards.
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
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
unit, 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-MMSB Metal Mounting Support Bracket
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)
point suspension of the assembly of Ceiling
Loudspeaker and Surface Mounting Box, a separate
metal suspension kit, LC1‑MSK is available.
LC1-CSMB Surface Mounting Box
LC1‑MSK Metal Suspension Kit
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.
LC1-CMR and LC1-CBB Ceiling Mounting Ring and Back
Box assembly
LC1-CSMB Surface Mounting Box
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
LC1‑MSK Metal Suspension Kit
LC1-MFD Metal Fire Dome
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.

LC1-PIB Pilot‑tone Indication Board
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.

This accessory consists of a C‑ring and two tile rails, to
be used for reinforce the ceiling material and to
spread out the pressure from the ceiling speaker
clamps. The C‑ring can be guided through the cut‑out
opening in the ceiling and placed on the back side of
the hole before inserting the loudspeaker. The tile rails
are suitable for 600 mm distance ceiling tile support
rails. This accessory consists of a set of two pieces.
