LBC 3011/x1 Panel Loudspeakers
www.boschsecurity.com
The Bosch panel loudspeakers and matching mounting
boxes are ideal for built-in sound installations in
shops, department stores, schools, offices, hotels and
restaurants. They are manufactured and finished to the
same exacting standards as all Bosch public address
systems and components, guaranteeing high quality,
and compatibility throughout the range.
Functions
The 6 W panel is equipped with a woofer and tweeter,
enabling excellent quality speech and music
reproduction. They are available with or without an
integral volume control (LBC 3011/51 and
LBC 3011/41, respectively). Nominal output power can
be preset to full, half, quarter or eighth-power
radiation (in 3 dB steps) by connecting the 100 V line
to the appropriate primary taps on the matching
transformer via a 2‑pole screw connector.
The white (RAL 9010) panels are injection-molded
from self-extinguishing, high-impact ABS material
(according to UL 94V0). They are finished with an
attractive perforated metal grill.

u
Surface-mounting and flush mounting boxes
The panel loudspeakers flush‑mount into rectangular
cut‑outs in cavity walls, ceilings, furniture or custommade cabinets. The panels have provision on the rear
side for mounting an optional line/loudspeaker
supervision board.
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.
Certifications and approvals
Voice alarm loudspeakers are specifically designed for
use in buildings, where performance of systems for
verbal evacuation announcements is governed by
regulations. The LBC 3011/x1 is designed for use in
voice alarm systems.
