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
u Water and dust protected to IP 65
u EN 54‑24 certified
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, hightemperature 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.

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.
