Functions

Voice alarm loudspeaker

Voice alarm loudspeakers are specifically designed for
use in buildings where performance of systems for
verbal evacuation announcements is governed by
regulations. The LC2‑PC30G6‑8 is designed for use in
voice alarm systems and is compliant with British
Standard BS 5839‑8 and EN 60849.

Protection

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. It is standard fitted
with a back‑can enclosure to increase protection of
the cable termination.
The loudspeaker has an emergency compliant ceramic
screw‑terminal block and thermal fuse.

Certifications and approvals

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 lessens the chance of failure or performance
deterioration.

Installation/configuration notes

Mounting

The loudspeaker is secured in ceilings using four
integral toggle anchors, and has been designed to
work together in a wide range of different ceiling
constructions. A tile bridge / C‑ring is included for safe
suspension in a drop ceiling that uses mineral wool, or
other fiber‑based ceiling tiles from 4 to 25 mm (0.16
to 1.0 in.) thick.
A circular template for marking a 272 mm (10.75 in.)
diameter hole is included with the loudspeaker.

Power setting

The unit has a three‑way emergency compliant ceramic
terminal block with screw connections (including
earth) suitable for loop‑through wiring. Four 100 V,
and five 70 V, primary taps are provided on the
matching transformer to allow selection of nominal
full‑power, half‑power, quarter‑power, eighth‑power
radiation (in 3 dB steps) and eight ohm. Selection is
done via a convenient switch on the front baffle.
