The LBC 3018/01 cabinet loudspeaker delivers
professional performance from a robust, yet
aesthetically designed metal enclosure. It is an ideal
loudspeaker for indoor use in offices, schools, car
parking, shopping centers and in areas where
vandalism is a potential hazard.
The cabinets are equipped with a high efficiency, dualcone loudspeaker offering a wide frequency range
suitable for both speech and music reproduction.
Functions
Voice alarm loudspeakers are specifically designed for
use in buildings, where the performance of PA-systems
is subject to official regulations. The LBC 3018/01 is
designed for voice alarm systems, and is compliant
with the EN 54-24 standard.
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 heatresistant, high-temperature wiring.
The cabinet has a provision for internally mounting the
optional line/loudspeaker supervision board.
Certifications and approvals
All Bosch loudspeakers are designed to withstand
operating at their rated power for 100 continuous
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
improved reliability under extreme conditions, leading
to higher customer satisfaction, longer operating life,
and lessens the chance of failure or performance
deterioration.

Dimensions in mm (in)
The cabinet is designed for both surface mounting on
walls and recessed mounting into brick or concrete
walls. The back‑box of the cabinet provides a selection
of mounting holes, even for mounting onto U40 and
MK installation boxes. The back‑box has two knockout
holes on the topside for two cable glands for loopthrough connection. For extra convenience, a safety
cord from the back‑box lets the installer temporarily
hang the front grille unit during installation.
Surface mounted (left) and recessed (right) mounted
The cabinet has a three-way terminal block with screw
connections suitable for loop-through wiring (including
earth) Four primary taps are provided on the matching
transformer to allow selection of nominal full-power,
half-power, quarter-power or eighth power radiation
(in 3 dB steps).
