Communications Systems | LBC 3950/01 Ceiling Loudspeaker

The LBC 3950/01 is a compact, 6 W loudspeaker with a
circular plastic grille. It has excellent audio performance
and is easy to install with its integral mounting clips. The
loudspeaker is IPx4 water protected from the front so it
can be installed in humid environments.

Functions

The LBC 3950/01 has a circular pattern plastic grille with
a plastic surround, finished in an attractive off-white
RAL color. The unobtrusive styling of this loudspeaker
complements modern interior lighting.
The loudspeaker feature a very wide opening angle, which
means fewer units are required to cover a given area. The
wide frequency range means better speech and music
reproduction. The unit is supplied with a 100 V matching
transformer with taps on the primary winding for full-
power, half-power, quarter-power and eighth-power
radiation.
The loudspeaker (with special treated paper cone), is IP 4
water protected from the front and can be applied in
humidity environments for example bathrooms, saunas,
atriums and swimming pool areas.

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 manufactured from self-extinguishing
high-impact ABS material (according to UL 94V0).
