u For large area, high-ceiling applications
u Optional bracket for fixed mounting
The Bosch Hemi-directional Loudspeaker is an easy to
install, innovative loudspeaker which projects
consistent and high quality sound, ensuring superb
reproduction of background music and high speech
intelligibility for paging or emergency calls. The
speaker’s opening angle and high sound pressure level
allows it to cover at least 700 m2, making it extremely
suitable for indoor high‑ceiling areas like warehouses,
transport and exhibition halls, mega stores and
swimming pools.
Functions
Voice alarm loudspeaker
The LS1‑OC100E‑1 is used in voice alarm systems and
is compliant with emergency standards. The
loudspeaker has built‑in protection to ensure that a
fire‑damaged loudspeaker does not cause failure of
the connected circuit. This ensures system integrity,
meaning loudspeakers in other areas can still be used
to inform people of the fire. The loudspeaker has
ceramic terminal blocks, a thermal fuse and heatresistant, high‑temperature wiring.
u Self‑restoring tweeter overload protection
u Provision for internal mounting of the optional line/
loudspeaker supervision board
u EN 54-24 certified
Materials
The loudspeaker is made of high‑impact ABS TSG, selfextinguishing according to class UL 94 V 0 and with
the highest flame retardant rating (UL 94 5VA). The
loudspeaker has a white and silver finish; the metal
grille has a silver finish. All metal parts are zinc plated.
Drivers
This acoustically innovative loudspeaker
accommodates 14 drivers in combination with
advanced positioning and filtering.

Installation/configuration notes
The loudspeaker can be suspended from a steel wire
or chain using Dee shackles (not supplied).
A separate accessory, LM1‑MSB‑1, is available for
applications where fixed suspension is required to
avoid any loudspeaker movement (such as rotation,
wobbling).
This accessory uses a set of zinc plated steel mounting
plates:
• one plate for mounting centrally onto the loudspeaker
(with fixing provisions)
• one plate for fixing onto the ceiling or roof
construction
• four fixing pins and spring clips
• four fixing screws
The mounting plates can be mechanically connected
with a standard 42.4 mm (DIN EN 10255) dia. tube
(not supplied by Bosch, but generally available in any
required length).
For extra safety, the loudspeaker has an eye bolt (M8
x13) with a maximum tensile strain of 1500 N for
attaching an optional safety cord.
The electrical connection box, under the suspension
cover, provides connection of the installation cable,
allowing loop through and provision for internally
mounting the optional line/loudspeaker supervision
board.
