u Master panel with capability for multiple distributed

panels

The Bosch EVAX System for high-rise applications is a
networked emergency relocation and paging system
with integrated two‑way fireman’s telephone system. It
operates with the Fire Alarm Control Panel (FACP) in a
building to provide automatic response to life safety
emergencies. While providing all necessary features
for an effective voice evacuation system, it can easily
convey evacuation, stay-in-place, or other public
address announcements and automatic messages with
multiple channels of simultaneous audio.
Configure your system to include Fire Fighter Phones
or Warden Stations as required, for fire fighter
communications to supplement 2‑way radios and for
use in areas of refuge assistance so trapped
individuals can communicate with fire command.
Smoke control features include automatic or manual
positive or negative pressurization for compartments,
floors, or stairwells. The simple to use interfaces allow
fire department authorities to take over controls and
communicate effectively.

u Operates as stand‑alone or connected to an FACP

u Network transmission over fiber optic or copper pair

cable

u Digitized live voice and prerecorded messaging

u Zone paging control

System overview

The maximum system configuration contains up to 256
Distributed Panels providing up to 2028 monitor and
control points.

Distributed Panels

The Distributed Panels communicate with the Master
Panel through the NetCom Loop. They typically
provide:

• Voice Evacuation Speaker Loops – dedicated data
and audio loops using a minimum of 18 AWG wire
with end-of-line resistors (EOLR).

• Fire Phone Loops – dedicated audio loop using a
minimum of 20 AWG twisted pair wiring with an
EOLR.

• Fan and Damper Loops – data loop using a minimum
20 AWG twisted pair wiring on which up to 32
modules can be attached. Each module provides two
points (one control and one monitor) for a total of 64
points on the circuit.

• Additionally, local Audio Amplifiers can be connected
to the Distributed Panels.

The Bosch Distributed Panels additional provide
specific accessories to support specific functions. The
HMB‑DP provides four audio circuits, the HMB‑DP/P
provides four Fire Phone circuits, and the HMB‑DP‑42
provides 16 audio circuits.

Functions

Master Panel

The Master Panel provides the high‑speed
communication loop (NetComm Loop), master
microphone control for live voice (PA) messages, dual
channel Digital Message Repeater (DMR) for up to
1000 prerecorded messages, and a 16‑switch control
module.

NetComm Loop

The NetComm Loop provides high‑speed RS‑485
communications over twisted pair, Category 5 UTP
cable. The network can be wired as Style 4 or Style 7
with a maximum of 4000 ft between panels and a total
loop length of 50,000 ft. The loop carries data and six
audio channels.
