FEATURES

Features

●

A VM-2000 Series amplifier can be combined to increase its system coverage number of speaker zones.

●

Use of the optional SV-200M Surveillance Board allows system-wide integrity to be conveniently monitored such as CPU-initiated automatic checking at pre-set times for open or shorted speaker lines, any speaker circuit ground leaks as well as power amp section malfunctions. Signals can be sent to a status display which simplifies maintenance and instantly calls attention to faults.

●

If the EV-200 Voice Announcement Board is used, five general-purpose messages and two emergency messages as well as a chime tone can be output. To record customized announcements and messages, the optional EV-350R Digital Announcer can be used. In addition, this allows adding a customized chime tone to the six built-in chime tones.

●

When a VM-2000 Series amplifier is used in combination with an emergency power supply unit*, a backup battery ensures uninterrupted operation during power outages.

* TOA DS-1000B or similar emergency power supply unit.

●

During emergency situations a VM-2000 Series amplifier can provide phased emergency broadcasts as per EN60849* standard.

●

Emergency broadcasts preempt system volume settings as well any external attenuators to ensure the broadcast is easily heard in any speaker zone.

●

Four priority levels can be set for general broadcasts. All priority levels of general broadcasts are overridden in an emergency situation while emergency broadcasts are supplied to all zones.

●

Standard speaker line distribution is rated for 100V applications. 50V or 70V speaker line distribution can also be selected by an easily performed internal wiring change.

●

The system will accept up to four remote microphones (RM-200M) that can be extended totally up to a maximum of 800 meters.

●

The independent speaker zones may be programmed into a maximum of five groups to receive group broadcasts. If a remote microphone is used, it can broadcast to Group 1 and Group 2.

●

The RM-200M remote microphone provides announcements with extraordinary clarity and freedom from distortion thanks to a highperformance built-in compression circuit.

GENERAL PURPOSE BROADCAST INPUT

External Connection Terminal

(VS-900)

Use of the VS-900 in conjunction with the VM amplifier permits broadcasts to be made from each station connected to the VS-900. Configure the connections so that two control signals are transmitted from the VS-900 to the VM amplifier's CTRL IN 1 and CTRL IN 2 terminals, then assign different zone groups to the two terminals. This enables each station to make broadcasts to the set zone group.

Example

In the VM amplifier group settings, assign Zones 1, 2, and 3 to Group 1, and Zones 4 and 5 to Group 2. Set the VS-900 to output an activation signal from CONTROL 1 when broadcasts are made from the RS-150, and to output an activation signal from CONTROL 2 when broadcasts are made from the RS-160. By setting the VM amplifier and VS-900 in this way, broadcasts can be made to Zones 1, 2, and 3 from the RS-150, and to Zones 4 and 5 from the RS-160.

GENERAL PURPOSE BROADCAST VOICE ANNOUNCEMENT BOARD

About the EV-200

The EV-200 digital sound source playback card for automatic broadcast is featured in the VM-2000 Series lineup. Using the optional card, emergency messages can be automatically broadcast or a chime tone sounded at preset times when using an external timer.

The following equipment are required to make automatic emergency broadcasts:

• VM-2000 Series System Management Amplifier (VM-2120/2240)

• EV-200 Voice Announcement Board

• CompactFlash (CF) memory card (made by SanDisk)

Messages need to be prerecorded on the CompactFlash memory card, which requires the following equipment:

• EV-350R Digital Announcer

• CompactFlash memory card adapter

Messages recorded in Program 1 - 8 sectors can be played back. (In the VM amplifier, the attributes of the message are determined according to the program number. Please refer to the section on how to

make recording.)

The EV-200 is provided with a Surveillance function. When a CF card-equipped EV-200 is installed, the VM amplifier outputs a pilot tone (1 kHz signal) from the EV-200 during periods when messages are not being broadcast. (This signal is not output to external equipment.) The VM amplifier constantly monitors this signal and checks to ensure that the EV-200 is operating correctly. If there is no card inserted, or any irregularities occur in the EV-200 to cause the VM amplifier not to detect the pilot tone, the EV Failure Output terminal will switch to "make" status, causing the VM amplifier's Failure indicator to light.

4-3-1

GENERAL PURPOSE BROADCAST VOICE ANNOUNCEMENT BOARD

Message Activation

Messages recorded on the CompactFlash memory card can be played back by activating (no-voltage "make" contact) the control I/O terminal located on the VM amplifier's rear panel, as in the case of the Remote Microphone. Record five different general-purpose messages on the CF card. If the pin corresponding to each message is activated, the messages can be individually played back.

NOTE: Custom-made switches that are appropriate for installation conditions are required to activate the messages.

(Please refer to P. 4-2-1, Operation and Broadcasting from the Remote Microphone.)

NOTE: A message activated by switches cannot be stopped till its end, while the message activated by a Zone/Message selector key on

remote microphone can be stopped during the broadcast by pressing the key again.

GENERAL PURPOSE BROADCAST VOICE ANNOUNCEMENT BOARD

Recorded CF Card Messages

Messages can be recorded on the CF card using the EV-350R. In the EV-350R, a series of messages is called a "program," which is called a "message" when played back using the EV-200 and VM amplifier. Up to 8 Messages (programs) are available, with Nos. 1 - 5 intended for general-purpose broadcasts, Nos. 6 - 7 for emergency broadcasts, and No. 8 for pre-announcement chime tone broadcasts.

Message (program) Nos. 1 - 5 Messages for general-purpose broadcasts are recorded. Recorded messages or chime tones are played back at preset times using an external timer. These messages can also be broadcast to groups programmed into the VM amplifier by pressing the Remote Microphone's Activation button.

Message (program) Nos. 6 - 7 Emergency messages for alert and evacuation are recorded. For Message 6, the recorded alert message is broadcast 5 times (in the example below) in repetition to permit investigation of the source of the emergency situation during the broadcast.

[Message example] "Attention please. The fire alarm system is indicating a fire. We're now investigating the cause.

Please await further instructions." For Message 7, the recorded evacuation message is played back without end even if the Number of repeats setting wouldn't be set as ENDLESS.

[Message example]

"There is a fire. Please evacuate as quickly as possible."

Message (program) No. 8 Standard equipment on the VM amplifier includes 6 different types of chime tones, however other types of chimes can be recorded on the CF card.

NOTE: The EV-350R permits more than 8 messages to be recorded, however no more than 8 messages can be played back

on the EV-200.

GENERAL PURPOSE BROADCAST ABOUT PRIORITY BROADCASTS

Broadcast Priorities

The VM-2000 Series features both emergency broadcast and general-purpose broadcast modes. Emergency broadcasts have priority over general-purpose broadcasts, and current general-purpose broadcasts are immediately switched over to emergency broadcast mode if an emergency broadcast is made. Three (Mic. > Evacuation > Alert) different priority levels (emergency microphone broadcast and EV broadcast) can be designated for emergency broadcasts, while 4 different levels of priority (Priorities 1, 2, and 3 and BGM) can be designated for general-purpose broadcasts. Broadcasts assigned higher priority can interrupt lower priority broadcasts.

Broadcast priorities

[Emergency Broadcast]

1. Emergency microphone broadcast. Announcements from the RM-200M microphone in emergency broadcast mode.

2. Emergency EV broadcast (evacuation). Evacuation message recorded for EV Program No. 7.

3. Emergency EV broadcast (alert). Alert message recorded for EV Program No. 6.

[General-Purpose Broadcast]

1. Priority 1 broadcast. EV 1 - 5, Inputs 1 - 3, TEL or RM 1 - 4 designated as priority 1.

2. Priority 2 broadcast. Inputs 1 - 3, TEL or RM 1 - 4 designated as priority 2.

The Number of Connectable Speakers

Up to 5 broadcast zones can be selected with the VM-2120 and VM-2240. The VM-2120's maximum power output is 120 W, while that of the VM-2240 is 240 W.

The following two patterns show the system where speakers of a total of 120 W are connected to the VM-2120 or speakers of a total of 240 W are connected to the VM-2420:

Pattern 1: All speakers connected to 5 zones. Pattern 2: All speakers connected to a single zone.

The only difference between the two patterns is whether or not the zones can be selected. Therefore, the speakers can be connected to any zone provided the speaker inputs do not exceed the maximum output of each amplifier.

Operation of the Quasi-Dual-Origination

Broadcast System

The quasi-dual-origination broadcast is available when the VM amplifier is connected to a BGM amplifier. Background music (BGM) input to the A-1000 BGM amplifier is broadcast over Zones 1 - 5 in Fig. 1. In Fig. 2, Individual Zone Selection keys 2 and 3 on the Remote Microphone are selected and the Talk switch is pressed to page Zones 2 and 3. In this event, since a call from the Remote Microphone takes precedence over the BGM, the BGM output to Zones 2 and 3 is interrupted. However, the BGM continues to play in Zones 1, 4 and 5 which were not selected by the Remote Microphone.

About Emergency Broadcasts

<TOA's Efforts to Make the VM-2000 Series Amplifiers Conform to European Safety Standards>

European Standard EN60849 Paragraph 4.1 (General System Requirements) describes emergency broadcast systems as follows:

a) When any alarm is detected, the system shall immediately disable any function not connected with its emergency role (such as

paging, music or general prerecorded announcements being broadcast to the loudspeaker zones requiring emergency broadcasts.

When emergency broadcasts are initiated from the Remote Microphone or from external equipment in the VM-Series system, all functions other than automatic broadcast of 2 types of recorded messages (warning and evacuation announcements) and manually initiated announcements from the Remote Microphone are disabled until emergency broadcast status is reset.

b) Unless damaged as a result of the emergency, the system shall be available for operation at all times.

VM-Series amplifiers are not equipped with switches to turn off the power supply of the entire system, making it possible to instantly initiate emergency broadcasts at all times.

c) The system shall be capable of broadcasting within 10s after primary or secondary power is applied.

VM-Series amplifiers can commence emergency broadcasts in approximately 6 seconds.

d) Except during the condition described in 4.1c), the system shall be capable of broadcasting a first attention-drawing signal within 3s

of being placed in an emergency mode by the operator or automatically on receipt of a signal from a fire or other detection system.

VM-Series amplifiers are not equipped with switches to turn off the power supply of the entire system, making it possible to instantly initiate emergency broadcasts at all times.

e) The system shall be capable to broadcast attention-drawing signals and speech messages to one or more areas simultaneously.

There shall be at least one appropriate attention-drawing signal alternating with one or more speech messages for this purpose.

VM-Series amplifiers are designed to provide emergency broadcasts of both an alert signal or an evacuation message prerecorded on the EV-200 digital voice recording unit over the entire area.

f) At any time the system operator shall be able to receive, by means of a monitoring system, indications of the correct functioning or

otherwise of the relevant part of the emergency system.

VM-Series amplifiers feature built-in failure detection circuitry as standard equipment. This circuitry monitors system conditions in conjunction with other failure detection circuitry supplied by the SV-200M. The outputs from these components enable the system operator to confirm that the system is operating correctly at all times.

g) Failure of a single amplifier or loudspeaker circuit shall not result in total loss of coverage in the loudspeaker zone served.

If a VM amplifier should fail, it can be switched over to an external standby amplifier. VM-Series amplifiers are also equipped with failure detection functions for individual output zones. If a short circuit failure hampering broadcasts to other zones is detected, that shorted zone can be disconnected from the system, enabling broadcasts to other zones to continue.

h) An attention-drawing signal shall precede the first message for 4s to 10s. Successive signals and messages shall then continued

until either changed in accordance with the evacuation procedure, or manually silenced. The interval between successive messages shall not exceed 30s and attention-drawing signals shall be broadcast whenever periods of silence might otherwise exceed 10s.

VM-Series amplifiers can record 2 different types of emergency message using the EV-200 recording unit. It is possible to separately record an alert tone and an emergency message and edit them. Since the emergency broadcast sequence can be programmed, broadcasts that meet the requirements of the projects can be easily realized.

i) All messages shall be clear, short, unambiguous and as far as practicable, preplanned. Where prerecorded messages are used

they shall be held in a non-volatile form, preferably in a solid-state store, and be continuously monitored for availability. The system design shall make it inherently impossible for an external source to corrupt or damage the store or its contents. NOTE - On grounds of reliability, it is preferable not to use storage media depending on mechanical devices.

Since the VM system's emergency broadcast messages are recorded on compact flash memory cards in the VM amplifier, there is no possibility of the contents becoming lost due to volatility. The availability of the recorded memory contents is constantly monitored, and if a failure should occur, it can be indicated on either the amplifier or Remote Microphone, or a failure signal can be output to connected external equipment. Since recordings are only made using external equipment (EV-350R), it is impossible for the recorded contents to become damaged during operation.

j) The language(s) used shall be specified by the purchaser.

VM-Series amplifiers permit the user to record emergency broadcast messages in their own language. What is more, the Remote Microphone's indication labels can be easily prepared in user-preferred local languages.

EMERGENCY BROADCASTS EMERGENCY BROADCASTS

Operation and Connection Examples as

an Emergency Broadcast Amplifier

The following system uses the VM amplifier as an emergency/general-purpose broadcast amplifier. Generalpurpose announcements are made using the microphone and BGM is normally broadcast. In the case of emergencies such as a fire:

Emergency messages recorded on the CF card are played back to provide an emergency situation alert and evacuation instructions. Any of the following 3 playback methods can be initiated.

(1) Press the Emergency Button on the Remote Microphone. (2) Transmit a signal — either detected by the fire alarm system or produced when the Fire button is pressed —

to the VM amplifier.

(3) Press the manual activation button to activate the VM amplifier's emergency function.

The emergency function is initiated, and the BGM broadcast stops while the emergency message is being output.

If it is confirmed that there is no danger of fire and the emergency broadcast is terminated, the interrupted BGM is restored. (Note that some broadcasts are not restored depending on the type of equipment connected. Please refer to Section Emergency Broadcast Sequence.)

General-purpose broadcast is not restored depending on its type.

[Emergency mode]

• The emergency mode refers to the state where the VM amplifier is making emergency broadcast or where the "VM amplifier's broadcast cutoff control" signal is being transmitted from external emergency broadcast equipment to the VM amplifier (refer to p-36 "CONTROL I/O CONNECTOR FUNCTIONS").

• When the VM amplifier is placed in the emergency mode that takes precedence over general-purpose broadcast mode, the Emergency indicators of both the amplifier and the Remote microphone will light.

[Restoration to general-purpose broadcast]

For the general-purpose broadcasts cut off when its mode enters the emergency mode, some are restored after emergency mode completion, and some are not.

Operation and Connection Examples

for a Local Amplifier

The following system uses the VM amplifier as a general-purpose local amplifier.

In this system, the VM amplifier normally functions as a local amplifier to provide broadcasts of BGM and announcements. If the emergency broadcast amplifier (installed separately from the VM amplifier to cover broadcasts for the entire building area) is activated and an emergency broadcast is initiated, the VM amplifier's speaker junction automatically switches to the emergency broadcast amplifier side, allowing output from the emergency broadcast amplifier to go through.

SURVEILLANCE FUNCTIONS SURVEILLANCE FUNCTIONS

SV-200M Functions

The failure detection circuitry included as standard-equipment in the VM-2120 and VM-2240 amplifiers permits

• Communication error output (the number of connected units needs to be set)

• Failure detection by way of the optional EV-200 unit.

By installing an optional SV-200M unit, the following failure detection functions can be added.

• Failure detection of output zones 1 - 5 Detection of shorted or opened circuits for individual lines + simultaneous detection of ground faults of 5 zones.

• Power amplifier failure detection.

When any of these failures is detected, a common failure output is generated in addition to an individual failure output. The failure indicator LEDs on the VM amplifier front panel and the Remote Microphone are also illuminated.

SV-200M Block Diagram

The power amplifier failure is determined by superimposing a 20 kHz pilot signal over the audio signal at the power amplifier input and monitoring the power amplifier output for the pilot signal. This failure detection is constantly enabled.

Speaker line ground failure is detected by monitoring all speaker lines after the power amplifier's output transformer secondary side in a group. Failures are assumed if the impedance at ground falls to under 50 kΩ. This detection is constantly enabled.

An impedance measuring method employing a 40 Hz pilot signal is used to detect the short- or open- circuit failures. Initially, each speaker line impedance is measured and its reading stored (initial setting). When the speaker line check is activated, the speaker line impedance is compared with the initial reading and failure is determined by impedance deviation.

6-1

SURVEILLANCE FUNCTIONS SURVEILLANCE FUNCTIONS

SV-200M Functions

The initial impedance setting is performed by pressing the SET switch on the SV-200M's panel or by external activation. The speaker lines the SV-200M can cover are those of approximately 1 W to 240 W (100 V line). If initial setting is not possible (speaker line impedance exceeds the measurable range), an initial setting error is output to provide short- or open- circuit information depending on the state. However, since whether all 5 output zones are used differs depending on the project requirements, when an open circuit is detected during initial setting, a common failure signal is not output, and thus the failure indicator LEDs do not light. When a short circuit is detected during initial setting, an initial setting error and the same output as was detected in the speaker line check are provided.

The speaker line check is performed by pressing the CHECK switch on the SV-200M's panel or by activating from the built-in timer or external equipment. If activated, the speaker line is disconnected from the power amplifier and is connected to the SV-200M for impedance measurement. If the impedance is approximately 50% lower than that of the initial setting, a short output is provided, and an open output if approximately 200% higher. If the measurement is completed, the speaker line is reconnected to the power amplifier to restart the broadcast.

If a shorted speaker line is detected, its zone is disconnected and maintained, while restarting broadcasts to other zones. The zone is disconnected because broadcasts cannot be made to other zones when even a single zone fails due to a short circuit. The shorted speaker line is kept disconnected until its status returns to normal.

The time required to check speaker lines of all 5 zones is approximately 20 seconds. During this duration, background music output and broadcast of Level 3 priority are interrupted. If broadcasts of priority higher than Level 2 or emergency activation or emergency cutoff states are enabled during the impedance check, the check will be interrupted and the broadcast initiated.

The built-in timer can be set for 10 - 60 minutes in 10-minute units. To set for shorter or longer intervals than this, use an external timer.

During broadcasts of a priority higher than Level 2 or during emergency broadcast or emergency cutoff states, initial setting or impedance checks cannot be activated. However, since the system remembers the activation, the impedance check will be activated after the broadcast or emergency cutoff state is completed. If Speaker line ground failure is detected, Initial setting and Impedance check cannot be activated. The initial setting and impedance check can be activated regardless of the power switch setting.

Since the SV-200M detects speaker line failure by measuring the impedance, it cannot be used in combination with 3-wire system attenuators. Be sure to use a 4-wire system attenuator when using an external attenuator.

Since speaker line impedance changes due to temperature and time, it is highly recommended that the initial settings for the speaker lines be re-initialized periodically after checking speaker line operation.
