The LBC 3099/41 is a flush-mounting ceiling
loudspeaker for applications where extra power is
required, such as rooms with high ceilings. It delivers a
high sound pressure level and has a wide frequency
range to ensure excellent speech intelligibility and
good quality music reproduction. It is used in
applications like shops, department stores, schools,
offices, sports halls, hotels and restaurants.
Functions
The LBC 3099/41 has a single-piece, 24 W, dual-cone
loudspeaker. A 100 V matching transformer is
mounted on the back of the frame. An attractive metal
grille is integrated with the front, and finished in an
unobtrusive white color (RAL 9010).
Voice alarm loudspeaker
Voice alarm loudspeakers are specifically designed for
use in buildings where performance of systems for
verbal evacuation announcements is governed by
regulations. The LBC 3099/41 is designed for use in
voice alarm systems and is compliant with emergency
standards.
The loudspeaker has built-in protection to ensure
that , in the event of a fire, damage to the loudspeaker
does not result in failure of the circuit to which it is
connected. In this way, system integrity is maintained,
ensuring loudspeakers in other areas can still be used
to inform people of the situation. The loudspeaker has
a ceramic terminal block, thermal fuse and heat
resistant, high-temperature wiring.
It can also be fitted with an optional fire-dome
LBC 3082/00 to increase protection of the cable
termination.
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.

Installation/configuration notes
LBC 3099/41 with LBC 3082/00 fire dome assembly
The unit has two built-in spring-loaded locking clamps
to secure it into a hole in suspended ceilings and
wallboards from 9 to 25 mm (0.35 to 1.0 in) thick. A
circular template for marking a 210 mm (8.3 in)
diameter hole is included with the loudspeaker.
Terminal Block
The unit has a three-way terminal block with screw
connections (including earth) suitable for loop-through
wiring. Three primary taps are provided on the
matching transformer to allow selection of nominal
full-power, half-power or quarter-power radiation (in
3 dB steps).
