The Plena Voice Alarm Controller is the heart of the voice
alarm system. It is the basis of the Plena Voice Alarm
System, and has all the essential functionality for
compliance with the EN 60849 and 54‑16 standards,
including full system supervision, loudspeaker line
impedance supervision, a supervised emergency
microphone on the front panel and a supervised message
manager.
The messages can be merged to allow even more flexible
use of pre-recorded announcements and evacuation
messages. The controller can be used as a stand-alone
system with up to six zones, or expanded to up to
60 zones using additional six-zone routers. Up to eight call
stations can be connected. Interconnections are made
using standard RJ45 connectors and shielded CAT-5
cable.
A built-in 240 W amplifier provides the power for the
emergency call channel and BGM. Additional Plena
Amplifiers can be added to provide two-channel
operation. All amplifiers are supervised. The audio output
uses standard analog audio 100 V line switching for full
compatibility with the Plena family of public address
equipment and Bosch EVAC-compliant loudspeakers. The
system is configured using DIP switches for basic
functionality and a PC for more advanced functions.
Functions
The controller has two BGM source inputs and a mic/line
input with configurable priority, speech filter, phantom
power and selectable VOX activation. A total of 16 priority
levels can be specified for microphone, call stations and
trigger inputs for optimum system flexibility.
The powerful 240 W output section has six transformerisolated 100 V constant-voltage outputs for driving 100 V
loudspeakers in six separate zones. The 100 V-technique
reduces line losses on longer distances and provides easy
parallel connection of multiple loudspeakers. All zones
may be individually selected from the front panel, and the
BGM output level in each zone can be individually set in
six steps. The controller supports A/B wiring.
Configuration software is provided on the CD included
with the unit. The CD also includes many useful programs,
such as MP3-ripping software, a sample-rate converter,
various audio and visual tools, and free, MP3-coded
music.

The amplifier output is also available as a separate output
on 100 V and 70 V. A separate 100 V call-only output
provides addressing for an area where BGM is not
required but where priority announcements are. Six
configurable volume-override output contacts are
available for overriding local volume controls during
priority calls. Both four-wire and three-wire schemes are
supported. An LED meter monitors the output.
Up to 255 messages can be stored in the internal 16 MB
flash ROM, without a need for battery backup. Each
message can have any length within the total available
capacity. Messages and configurations are uploaded from
a PC via USB 2 into the memory, after which the unit
operates without a PC connection. The standard WAVformat is used for the messages, and sample rates of
8 kHz up to 24 kHz with 16-bit word length (linear PCM)
are supported. This gives up to 17 minutes of recording
time with CD-quality signal-to-noise ratio.
The unit has 12 contact trigger inputs for business and
emergency (EMG) calls. Each can be configured for a
message consisting of a sequence of up to eight wave
files. In this way some wave files may be used in various
combinations with other messages, optimizing flexibility
and the amount of storage space used . Multiple
messages can be merged to form one integrated message.
A zone selection, together with this sequence can be
configured for each trigger input.
