The LP1‑BC10E‑1 is a powerful 10 W bidirectional sound
projector intended for high quality speech and music
reproduction in indoor and outdoor applications. The two
loudspeakers facing in opposite directions are ideally
suited to applications such as tunnels, long corridors and
shopping arcades. 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 high‑quality drivers in combination with
advanced filtering has resulted in a very natural sound
reproduction.
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‑BC10E‑1 is designed for use in voice
alarm systems. The sound projector is pre‑wired for use
with an optional line/loudspeaker supervision board
externally 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 according to class UL 94 V 0, 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.
Safety aspects
In common with all Bosch products, care is taken to meet
high safety standards. This sound projector complies with
the relevant safety and installation regulations of
EN 60065, BS 5839‑8 and EN 60849. All ABS parts are
self-extinguishing (according to UL 94 V 0)

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 directed. 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 loop‑through 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 color coded wire
to the terminal block.
