The Bosch Voice Evacuation systems and expansion panels
provide a variety of options that can be easily added to an
existing fire alarm control panel system for area of assembly
applications and for high‑rise voice evacuation not requiring
firemens' phones. Choose up to 2000 W of audio amplifier
power to meet your speaker power requirements. You can
supervise multiple zones through your choice of zone
splitters.
The EVAX25, EVAX50, and EVAX100 respectively provide
25 W, 50 W, and 100 W of audio amplifier power in a
standard‑size enclosure. The EVAX150 has one 50 W audio
amplifier and one 100 W audio amplifier in a double‑size
enclosure. The EVAX200 has two 100 W amplifiers in a
double‑size enclosure.
Customize these systems to satisfy most application
requirements by adding expander panels, expander
modules, or zone splitters. Expanders can be grouped
together in any combination to provide up to 2000 W of
audio power.

BOSCH Voice Evacuation Systems
All Bosch voice evacuation systems include all the
necessary features to provide an effective voice evacuation
system:
The Bosch system expander panels provide an easy and
cost-effective way to increase the output power of a Bosch
voice evacuation system. They can also provide a
manually‑activated emergency paging panel for buildings.

Speaker Wiring Requirements
Category
Product
The 25 V speaker circuits of most voice evacuation systems
are classified as power‑limited wiring and can be run with
other fire alarm wiring without ill effects. No special cabling
is required. Standard power‑limited fire alarm cable (FPL)
is sufficient for most applications; however, certain
addressable systems can generate extraneous noise from
their addressable loop. Because these addressable systems
cannot use shielded cable, shielding of the evacuation
speaker circuit helps to eliminate noise picked up and heard
in the speakers. When using 70 V circuits, separate them as
described in the National Electrical Code.

Generally, 18 AWG (1.0 mm) wire is adequate for speakers.
Heavier wire is needed if loads are high or the runs are long.
The following table indicates typical wire lengths for
specific wire sizes and speaker loads. It assumes that there
is an even distribution of speaker load and that a 20% drop
at the last device is allowable.

Speaker Placement
25 VRMS Output:
Choose speakers that deliver a minimum ambient sound of
15 dB above the normal ambient noise level. In
high‑ambient noise areas, speakers should be tapped at
15 dB to 21 dB above the ambient noise level and placed
closer to one another to ensure that voice messages are
intelligible.

System Power Requirements

All Bosch voice evacuation systems require 120 VAC
connected to the system's power transformer. Standby
power is supplied, in case of AC power failure, by standby
batteries (not supplied). The EVAX25, EVAX50, and
EVAX100 require two 12 VDC, 7 Ah standby batteries. The
EVAX150 and EVAX200 require four 12 VDC, 7 Ah standby
batteries.

areas and 2 W for every 1500 ft (139 m ) in divided
areas. For wall‑mount speakers, use 1 W of speaker
2

power for every 2000 ft (186 m ) of area covered in
2
2
open areas and 1 W for every 1500 ft (139 m ) in
divided areas.
Speaker Power Requirements
System power (total wattage) must be sufficient to supply
the power required by all of the speakers on the system.
Speaker transformers can often be tapped for different
wattages (usually, ¼ W, ½ W, 1 W, etc.). A system rated at
25 W of audio power can power a speaker load of 25 W. This
can be made up of 25 speakers each tapped at 1 W, 50
speakers each tapped at ½ W, or any mathematical
combination that is less than or equal to 25 W.
