Bosch Voice Evacuation Systems  
Digitally‑recorded automatic evacuation message (up  
to 4 minutes of message capacity)  
Alarm and alert signals  
Live microphone override of message and tone  
Compatible with 12 V or 24 V, analog‑addressable or  
microprocessor‑based fire alarm control panels  
(FACPs)  
Clean dead‑front construction  
Easy installation and operation  
24‑hour backup with 7 Ah batteries installed (batteries  
not supplied)  
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.  
System Overview  
Optional Expander Panels  
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.  
Features of the EVAX25E, EVAX50E, and EVAX100E:  
Audio amplifier  
Digital message repeater (DMR)  
120 VAC power transformer and battery charger  
Tone generator  
Paging microphone  
Surface‑mount or semi‑flush‑mount enclosure with a  
Audio amplifier  
120 VAC power transformer and battery charger  
Tone generator  
Paging microphone  
hinged, key‑locked door in charcoal‑gray (standard) or  
red (optional)  
Standard‑size enclosure with a hinged, key‑locked door  
The EVAX150E and EVAX200E expander panels provide the  
same features with additional power in a double‑size  
enclosure housing two amplifier modules.

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

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.
