Important Safeguards
Prior to installing or operating this product, always read
the Important Safety Instructions which are available as
a separate document (9922 141 7014x). These
instructions are supplied together with all equipment
that can be connected to the mains.

Important Notices
When using routers, keypads or more than one call
station, configure the controller using the supplied
software.
Use shielded cable (Cat-5) between the routers and the
controller. Do not connect the shield to both the
controller and the router!
The factory default setting of the Plena Voice Alarm
Controller is as follows:
• Stand-alone unit configured for an ISO 60849
compliant system when used with a spare power
amplifier from the Plena range and compliant wiring
and loudspeakers.
• One channel system.
• Supervision on for:
• Loudspeaker lines
(90 seconds interval, 15% accuracy)
• Main and spare power amplifier
• Short to ground (“Ground short”)
• Mains and battery power
•EMG mic
•Memory
Please note that when used with the factory default
configuration:
• The background music (BGM) is muted when no
spare power amplifier is connected. Disabling the
spare power amplifier supervision or overall
supervision restores the BGM.
• The BGM will not be present in non-selected zones
during a call. If this is desired, connect a spare/call
power amplifier and switch the system to 2-channel
mode.
Thank you for choosing a Bosch Security Systems
product.

1 Introduction
1.1 Purpose
The purpose of the Basic System Manual is to provide
information that is required to install, configure and
operate a basic Plena Voice Alarm System. By
definition, such a system is installed, configured and
operated without a PC.
1.2 Digital document
The Basic System Manual is also available as a digital
document in the Adobe Portable Document Format
(PDF). All references to pages, figures, tables, etc. in this
digital document contain hyperlinks to the referenced
location.
1.3 Intended audience
The Basic System Manual is intended for installers and
users of a basic Plena Voice Alarm System. Installers
and users of extensive systems should refer to the
Installation and User Instructions (see section 1.4).
1.6 S ign s
Except for note alerts, the nature of the effect that can
be caused when the alert is not observed, is indicated
using a sign. For note alerts, the sign provides more
information about the note itself. In this manual, the
following signs are used in combination with alerts:
Note
General sign for notes.

Manual (9922 141 1038x).
1.5 Alerts
In this manual, four types of alerts are used. The alert
type is closely related to the effect that may be caused
when it is not observed. These alerts - from least severe
effect to most severe effect - are:
• Note
Alert containing additional information. Usually, not
observing a note alert does not result in damage to
the equipment or personal injuries.
• Caution
The equipment can be damaged if the alert is not
being observed.
• War ning
Persons can be (severely) injured or the equipment
can be seriously damaged if the alert is not being
observed.

2 System Overview
2.1 Voice Alarm System
2.1.1 Introduction
The Plena Voice Alarm System is a public address and
voice alarm system in which all the necessary features
for compliance to evacuation standards such as
IEC60849, NEN2575 and BS5839/8 are integrated.
2.1.2 Application types
Typically, the Plena Voice Alarm System is used to
create small systems that must comply to evacuation
standards, medium-sized systems in which one call
channel is enough and large systems that consist of
many small zones.
2.1.3 Application areas
The application areas of the Plena Voice Alarm System
include:
• Supermarkets, shops
•Factories
• High-rise buildings
• Office buildings
•Schools
• Recreational facilities
•Hotels
• Small airports
2.1.4 Plena
The Plena Voice Alarm System is part of the Plena
product range. Plena provides public address solutions
for places where people gather to work, worship, trade
or simply enjoy themselves. It is a family of system
elements that are combined to create public address
systems tailored for virtually any application. The range
includes mixer, pre, system and power amplifiers, a
source unit, digital message manager, feedback
suppressor, conventional and PC call stations, an ‘All-inOne’ system and a voice alarm system. Each element is
designed to complement all others thanks to matched
acoustical, electrical and mechanical specifications.
2.2 Basic system
As mentioned before, the scope of this manual is a basic
system. By definition, a basic system is installed,
configured and operated without a PC. Such a system
can only consist of:
• 1x LBB1990/00 Voice Alarm Controller (required).
• 1x LBB1956/00 Call Station (optional).

2.3 Voice alarm controller
2.3.1 Introduction
The LBB1990/00 Voice Alarm Controller is the heart of
the Plena Voice Alarm System. The voice alarm
controller distributes emergency calls, business calls as
well as background music (BGM) to up to 6 loudspeaker
zones.
figure 2.2: Voice Alarm Controller
Note
When the voice alarm controller has been
purchased in the Asian-Pacific Region, the
emergency button has a different cover.
2.3.2 Hand-held microphone
The voice alarm controller is equipped with a hand-held
microphone, which can be used to make emergency
calls.
2.3.3 Internal power amplifier
The voice alarm controller has a 240 W internal power
amplifier, which can be used in 1-channel or 2-channel
mode. In the 1-channel mode, all calls and BGM are
amplified by the internal power amplifier. If desired, an
external power amplifier can be connected for spare
switching. In the 2-channel mode, the BGM is amplified
by the internal power amplifier, whereas the calls are
amplified by an external power amplifier.
2.3.4 Internal message manager
The voice alarm controller has an internal message
manager, which maps wave files (.wav) to messages that
can be played by the Plena Voice Alarm System.
2.3.5 Supervision
All necessary supervision features for compliance to
evacuation standards are integrated into the voice alarm
controller. If supervision is enabled and a fault is
detected, the voice alarm controller lights a LED on its
front panel that indicates the cause of the fault.
2.3.6 Overview
See figure 2.3 for an overview of the controls,
connections and indicators on the voice alarm
controller:
1 Power LED/VU Meter - A combined power
indicator and VU meter. The green power LED is lit
if the voice alarm controller is connected to the
mains or back-up power and switched on. The VU
meter indicates the master VU level: 0 dB (red), - 6
dB, -20 dB (yellow).
2 Fault indicators - Twelve yellow system fault
LEDs (Processor reset, Network, Call/EMG, Music/
Spare, Ground short, Input, Mains, Battery, Message,
EMG mic, RCP and Router) and twelve yellow
loudspeaker line fault LEDs. Fault indication is only
possible if supervision is enabled (see section 5.7). If
supervision is disabled, the yellow Disabled LED is
lit.
3 Fault state buttons - Two buttons to acknowledge
(Ack) and reset (Reset) the fault state (see section
5.7).
4 Emergency state buttons - Two buttons to
acknowledge (Ack) and reset (Reset) the emergency
state (see section 5.6).
5 Emergency call zone selectors - Six buttons to
select the zones to which the emergency call must be
distributed (see section 5.6). Each button has a green
and a red LED. The six red LEDs indicate the zones
that are selected for the emergency call. The six
green LEDs indicate the zones in which a business
call is running.

6 BGM zone selectors - Six buttons to select the
zones to which the BGM is distributed (see section
5.4). Each button has a green LED and a rotary
knob. The six green LEDs indicate the zones to
which BGM is distributed. The six rotary knobs are
local volume controls that can be used to adjust the
volume of the BGM in each zone.
