Notice
To be compliant with EN 54‑24:
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
improved reliability under extreme conditions, leading
to higher customer satisfaction, longer operating life,
and lessons the chance of failure or performance
deterioration.
The loudspeaker must be installed with the
back‑box LC3‑CBB.

dB SPL
The loudspeaker has built‑in protection to ensure 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 screw‑terminal
connection block, thermal fuse and heat‑resistant high
temperature wiring.
Four primary taps for 100 V are provided on the
matching transformer to allow selection of nominal
full‑power, half‑power, quarter‑power and
one‑eight‑power.
The optional back‑box (LC3‑CBB) protects the rear of
the loudspeaker from dust, falling objects, makes the
unit vermin proof and prevents sound traveling via the
ceiling cavity to adjacent areas.
The back‑box is assembled with the loudspeaker by
means of a snap‑in construction and has knock‑out
holes for two grommets (11 mm) and for two cable
glands (20.5 mm).
