u Superb speech and music reproduction
u Integrated connection cable
The LP1‑UC10E‑1 is a powerful, 10 W sound projector
intended for high quality speech and music
reproduction in indoor and outdoor applications. The
state‑of‑the‑art design is matched to both modern and
traditional style environments. The sound projector is
suitable for use in voice alarm systems.
Functions
Superb sound quality
The use of a high‑quality driver has resulted in a very
natural sound reproduction with excellent bass
response.
Voice alarm loudspeaker
Voice alarm loudspeakers are specifically designed for
use in buildings where performance of systems for
verbal communication announcements is governed by
regulations. The LP1‑UC10E‑1 is designed for use in
voice alarm systems. The sound projector is pre‑wired
for use with an optional line/loudspeaker supervision
board external mounted. The loudspeaker has built‑in
protection to secure 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
u Ceiling or wall mounting
u Water and dust protected to IP 65
u EN 54‑24 certified
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, hightemperature wiring.
The sound projector is made from high-impact selfextinguishing ABS according to class UL 94 V0,
finished in white.
Certifications and approvals
Quality assurance
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 lessons the chance of failure or performance
deterioration.

Installation/configuration notes
Mounting
Ease of installation is realized in the way of mounting:
first the mounting plate is fixed to the wall or ceiling,
secondly a safety cord is attached to the mounting
plate, allowing the installer temporarily hang the
loudspeaker during installation. After making the
connections, the sound projector can be fixed to the
mounting plate, by means of a fixing screw nut, and
the horizontal direction can be fixed. A cover plate
covers screws and electrical wiring. The versatile
mounting bracket allows the sound projector to be
horizontal and vertical directed. The vertical direction
can be permanent fixed with a recessed socket head
screw via a small hole located in the rear housing The
cover plate is provided with two cable – or 16 mm
(0.63 inch) conduit entries (covered as standard
supplied) in opposite position, suitable for loopthrough cabling.
Power setting
A ceramic terminal for electrical connection is
provided. The loudspeaker is standard connected to
full power. Half‑power, quarter‑power or eighth‑power
can be selected by connecting the appropriate colorcoded wire to the terminal block.
