Plena Voice Alarm System | Basic System Manual | Important Notices

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.

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.

2.1.1

System Overview

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.

2.1.4

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-in-

One’ system and a voice alarm system. Each element is designed to complement all others thanks to matched acoustical, electrical and mechanical specifications.

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

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.

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.

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.

2.3.6

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).

3.10 Loudspeakers

The voice alarm controller has 6 zone outputs (Z1 to

Z6 ). Each zone output consists of 2 redundant loudspeaker lines (line A and line B). Normally, calls and BGM are distributed to a zone over both loudspeaker lines. If one of the loudspeaker lines of a zone fails, it is still possible to distribute calls and BGM to the zone over the remaining loudspeaker line (see figure 3.7).

If it is necessary to detect the removal or failure of a single loudspeaker, the following is advised:

• Do not connect more than 5 loudspeakers to the same loudspeaker line (line A or line B). Field tests have shown that the impedance of loudspeakers and loudspeaker lines varies with temperature and age.

The limit of 5 loudspeakers is set due to this variation. In a more stable environment, the number of loudspeakers can be higher.

• Make sure that all loudspeakers connected to the same loudspeaker line have the same impedance.

LBB1990/00

Note

The impedance measurement of the Plena Voice

Alarm System has an accuracy better than 2%.

The system only generates a fault if the line impedance difference is greater than 15%

(default accuracy).

Note

The maximum load for the internal power amplifier of the voice alarm controller is 240 W.

However, if the voice alarm controller is used in

2-channel mode and an external 480 W amplifier is connected to it, the maximum loudspeaker load can be 480 W at 100 V. This is because in 2-channel mode, the internal power amplifier of the voice alarm controller is used for BGM only and distributes BGM at

-3 dB, from which follows that the maximum power output is 240 W at 70 V and that the loading caused by 100 V loudspeakers at 70 V is also 240 W. The external amplifier is used for calls only with 480 W output power and 100 V loudspeaker line voltage.

The voice alarm controller has 6 override outputs; 1 for

each zone in the system (see figure 3.8). These are

suitable for 4-wire override (24 V) as well as for 3-wire override.

Internally, the positive override pins (Z+) are all connected to either the NC or the NO contact of the

Volume Override

output (see figure 3.9). The negative

override pins (Z-) are all connected to earth.

Normally, when there are no active calls, the Z+ pins are internally connected to the NC contact of the

Volume Override . At the moment a call is started in a zone, the Z+ pin of the zone is internally connected to the NO contact of the Volume Override. So, the NC and the NO contacts determine which voltage is supplied to the positive pins of the override outputs (Z+).

To create a 3-wire volume override, see figure 3.11:

Note

It is not possible to use 3-wire volume override in a basic system, because it must be enabled using the configuration software. See the

Installation and User Instructions

(9922 141 1037x) and the Configuration

Software Manual (9922 141 1038x) for more information.

Note

It is not possible to use 3-wire volume override in combination with redundant loudspeaker lines

(line A and B, see figure 3.7). If redundant loudspeaker lines are needed, use 4-wire volume override (see figure 3.10).

• Connect the 100V output of loudspeaker line A to the 100 V input of the volume control.

• Connect the 100 V/0 V (CALL/RTN) of the transformer to the 100V output of loudspeaker line

B

.

• Connect the 0 output of loudspeaker line A to the

0 V of the loudspeaker.

• Enable 3-wire volume override in the configuration software.

The voice alarm controller has one line output (see figure 3.12). This output has a double cinch socket. Both cinch sockets contain the same, mono signal, which consists of the current BGM and calls. The line output can be used to connect the voice alarm controller to a recording device (e.g. a tape-deck).

3.13 Mic/line input with VOX functionality

The voice alarm controller has 1 mic/line input with

voice-activated (VOX) functionality (see figure 3.13).

This input has two sockets; one balanced XLR socket and a balanced 6.3 mm jack socket. The signals from both sockets are mixed to form a single input signal.

In basic systems, the default priority of the mic/line input with VOX functionality is 6. This means that it can be used to make business calls (e.g. with a

PLN-MM Plena Message Manager). The input automatically starts a business call if the input is higher than -20 dB (100 mV for line and 100

µ

V for microphone inputs) or if the VOX switch is closed (see

figure 3.14).

If the APR mode switch (see figure 4.1) is in the ON

position, the system is in the Asian-Pacific Region (APR) mode. In APR mode, the system operates according to the emergency standards of the Asian-Pacific Region.

For a basic system, the differences between normal operation and the APR mode are:

•

When the emergency button (see figure 2.3, no. 12)

is pushed on the front of the voice alarm controller, an alarm message is automatically started. This message is automatically repeated.

• In the APR mode the red LED, which during normal operation indicates that the zone is selected for an

emergency call (see figure 2.3, no. 5), does not work.

• In the APR mode the green LED, which during normal operation indicates that a business call is

running in the zone (see figure 2.3, no. 5), indicates

that an emergency call is running in the zone.

Processor supervision

If supervision is enabled (see section 4.5.1), the

processor of the voice alarm controller is supervised by a watchdog. If the watchdog triggers, the Processor reset indicator on the front panel of the voice alarm controller is lit. Then, the program memory is checked and the processor resumes operation within 10 seconds.

The indicator remains on until the fault is acknowledged and reset.

Plena Voice Alarm System | Basic System Manual | Configuration en | 29

4.5.4

Message supervision

If supervision is enabled (see section 4.5.1), the internal

message manager of the voice alarm controller is supervised. This message supervision consists of supervision of the wave player using a check-sum and supervision of the audio path using a pilot tone.

4.5.6

Emergency microphone

If supervision is enabled (see section 4.5.1), the audio

path and the PTT switch of the emergency microphone are monitored from the capsule to the connection with the voice alarm controller.

4.5.5

Line supervision

4.5.5.1

Introduction

If supervision is enabled (see section 4.5.1), all

loudspeaker lines are supervised. Line supervision consists of:

•

Short-circuit supervision (see section 4.5.5.2).

•

Impedance supervision (see section 4.5.5.3).

•

Short-to-ground supervision (see section 4.5.5.4).

4.5.5.2

Short-circuit supervision

The voice alarm controller continuously monitors all loudspeaker lines in the system for short-circuits. If a short-circuit is detected, the line output of the short-circuited line is isolated and shut down within 200 ms. The system will remain operational. If the line is dual-redundant connected (A and B) the short-circuited line remains operational as well.

4.5.7

Mains power supervision

If supervision is enabled (see section 4.5.1), the

availability of the mains power is supervised.

4.5.8

Battery supervision

If supervision is enabled (see section 4.5.1), the

availability of the back-up power is supervised.

4.5.9

Internal power amplifier supervision

If supervision is enabled, the internal power amplifier of the voice alarm controller is supervised. The function of this power amplifier depends on the position of the 2ch operation

switch (see section 4.5.11).

table 4.3: Internal power amplifier functions

Operational mode Function

1-channel

2-channel

BGM/Call power amplifier

BGM/Spare power amplifier

4.5.5.3

Impedance supervision

If supervision is enabled, the voice alarm controller measures the impedance of all loudspeaker lines once every 90 seconds. The reference values for impedance supervision are stored in the voice alarm controller

during the system calibration (see section 5.3). If a

difference of > 15% is detected between the measured line impedance and its reference value, the line is considered faulty.

4.5.10 External power amplifier supervision

If supervision is enabled and the 2ch operation switch

(see section 4.5.11) is in the ON position, the external

power amplifier is supervised. In 2-channel mode, the external power amplifier is always the call power amplifier.

Note

For a correct impedance supervision, connect

loudspeakers as described in section 3.10.

4.5.5.4

Short-to-ground supervision

If supervision is enabled, the voice alarm controller continuously monitors all loudspeaker lines in the system for short-to-ground situations. If a leakage current > 30 + 15 mA is detected in a line, the line is considered faulty.

4.5.11 1 channel and 2 channel operation

4.5.11.1

Introduction

If the 2ch operation switch (see figure 4.1) is in the ON

position, the voice alarm controller operates in the

2-channel mode. If the 2ch operation switch is in the

OFF position, the voice alarm controller operates in the

1-channel mode.

4.6.1

Introduction

The type of source that is connected to the mic/line input with VOX functionality is set using the Mic/Line switch on the rear of the voice alarm controller (see

figure 4.3).

• If the source is a microphone, put the switch in the

Mic

position.

• If the source is a line-level source, put the switch in the Line position.

4.5.11.2

1-channel mode

In the 1-channel mode, all calls and BGM are amplified by the internal power amplifier of the voice alarm controller. If desired, an external power amplifier can

be connected for spare switching (see section 3.9). In 1-

channel mode, all calls will interrupt the BGM. The

external power amplifier is not supervised (see section

4.5.10).

4.5.11.3

2-channel mode

In the 2-channel mode, the BGM is amplified by the internal power amplifier of the voice alarm controller.

The calls are amplified by the external power amplifier, which is connected to the voice alarm controller

(see section 3.9). If the external power amplifier is

faulty, the calls are amplified by the internal power amplifier. In 2-channel mode, calls do not interrupt the

BGM. Both the internal power amplifier and the

external power amplifier are supervised (see section

4.5.10).

E

Emergency call

Live speech, alert message or alarm message that is distributed in the emergency state. Emergency calls can only be made with the voice alarm controller.

Emergency state

Emergency calls can only be distributed in the emergency state. This state is entered by pushing the red emergency button on the front panel of the voice alarm controller. At the moment the emergency state is entered, a beeper starts. Simultaneously, the default alert message and the default alarm message are distributed to all zones in the system.

F

Fault state

If a supervised function fails, the system automatically enters the fault state. It starts a beeper, de-energizes the Fault Status output contact and lights an indicator on the front panel of the voice alarm controller.

L

LED

Light Emitting Diode. Electronic component that frequently is used as indicator.

P

PC

Personal Computer.
