The LP1-UC10E 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 in combination with

advanced filtering, 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 is designed for use in voice
alarm systems and is compliant with British Standard BS
5839 part 8. 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 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.
The sound projector is made from high-impact self­extinguishing ABS acc. to class UL 94 V 0, finished in off­white.

Certifications and Approvals

Quality assurance
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.

Safety aspects
In common with all Bosch products, care is taken to

meet high safety standards. All ABS parts are self­extinguishing (according to UL 94 V 0) This sound
projector complies with the relevant safety and
installation regulations of EN 60065 and BS 5839 part 8.

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 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 cover plate is
provided with 2 cable – or 16 mm conduit entries
(covered as standard supplied) in opposite position,
suitable for loop- through cabling.

Power setting
A ceramic terminal for electrical connection is provided.

The loudspeaker is standard connected to full power.
Half-power or quarter power can be selected by
connecting the appropriate color coded wire to the
terminal block.
