Bosch Voice Evacuation Systems

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.

BOSCH Voice Evacuation Systems

All Bosch voice evacuation systems include all the necessary features to provide an effective voice evacuation system:

•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 hinged, key‑locked door in charcoal‑gray (standard) or red (optional)

▶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 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.

Optional Expander Panels

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

•120 VAC power transformer and battery charger

•Tone generator

•Paging microphone

•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.
