2. GENERAL DESCRIPTION

[System Management Amplifier VM-2120/VM-2240]

Featuring outstanding audio performance, the TOA System Management Amplifier VM-2120/-2240 satisfies the growing need for reliable and efficient communications for various applications, especially for mediumsized facilities including office building, factories, hospitals, and transportation terminals.

The VM-2120 (120 W) and VM-2240 (240 W) are multifunctional amplifiers that can be mounted in an EIA-

Standard equipment rack (3-unit size). Both units come with 4 audio inputs including the background music input, and the speaker output section which has an internal attenuator and 5-zone selector. They permit not only general-purpose broadcast, but also Emergency Broadcast based on the EN60849 Standard which gives pre-recorded voice instructions* 1 in the emergency situation. Broadcast can be made from an optional RM-

200M Remote Microphone as well as from the amplifier, and can be remotely controlled from external equipment. In addition, both amplifiers feature the surveillance function* 2 which automatically checks the system for failures.

* 1 An optional EV-200 Voice Announcement Board is required.

* 2 An optional SV-200M Surveillance Board is required.

[Remote Microphone RM-200M]

The RM-200M is a dedicated unit for both the VM-2120 and VM-2240, and permits Emergency Broadcast as well as general-purpose broadcast.

[Remote Microphone Extension RM-210]

The RM-210 is an extension unit for the RM-200M's key operating section.

3. FEATURES

• Broadcasts of up to 480 W can be made to up to 10 zones individually or simultaneously.

(when 2 VM-2240's are used).

• Permits monitoring of individual speaker line or power amplifier failures for status indication.

(Requires the optional SV-200M Surveillance Board.)

• Reproduces 5 general-purpose messages, 1 chime tone, and 2 emergency messages.

(Recordable as you like using the optional EV-200 Voice Announcement Board)

• Six different built-in chimes and prerecorded chime tones (by the EV-200) can be selected to attract attention to broadcasts.

• Backup battery maintains operation during power failures.

• Emergency broadcast based on the EN60849 Standard provides prerecorded voice instructions in the emergency situation.

• Emergency broadcast bypasses both the amplifier volume control and the external attenuator, making sure that the broadcast is heard throughout all zones.

• Features following broadcast priority levels: the highest level for Emergency broadcasts and 4 levels for general-purpose broadcasts.

• Speaker lines for 100 V line applications (standard) or for 50 V or 70 V line applications (enabled by changing the unit's internal wiring).

• Up to 4 remote microphones can be connected, and their total connection cables can be extended to 800 m.

(RM-200M/-210)

• Speaker zones can be programmed into up to 5 groups for group broadcast.

(The remote microphone can broadcast to the Groups 1 and 2 out of the 5 groups.)

• Clear, distortion-free announcements owing to the internal compressor circuitry. (RM-200M/-210)

4. HANDLING PRECAUTIONS

[VM-2120/VM-2240 and RM-200M/RM-210]

To clean, be sure to first switch off the power supply to the unit, then wipe with a dry cloth. When the unit gets very dirty, use a cloth damped in a neutral cleanser. Never use benzene, thinner or chemically-treated cleaning cloth because such volatile liquids could deform or discolor the unit.

[VM-2120/VM-2240]

• When the EV-200 is mounted, never move the unit from one place to another with the Flash Card inserted because the EV-200 or the CompactFlash card may fail.

• Avoid inserting or withdrawing the CompactFlash card while the unit is alive.

5. INSTALLATION PRECAUTIONS

[VM-2120/VM-2240 and RM-200M/RM-210]

• Do not install the unit in locations exposed to the direct sunlight or heaters, as the unit could be deformed or discolored.

• Avoid installing or storing the unit in dusty or humid locations, as doing otherwise could cause the unit's failure.

• Keep the unit as far away as possible from a fluorescent lamp, digital equipment, PC or other equipment which generate high frequency noise.

[VM-2120/VM-2240]

• Do not block the ventilation slots on the upper, right and left, and rear sides to allow inside heat radiation.

• Keep at least 50 mm space from the unit's right and left sides for heat radiation.

8.3. Emergency Broadcast Operation (Typical Example)

Step 1. Alert Broadcast

Open the RM-200 Remote Microphone's Emergency broadcast switch cover, and press the switch.

EMERGENCY

A pre-recorded Alert signal tone and Alert announcement will be alternately broadcast to the entire zone for the preset number of repetitions.* 1 The EMERGENCY indicators of the RM-200M and the

VM amplifier come on.

Alert (or Evacuation) broadcasts terminate all current generalpurpose broadcasts.

(The Alert broadcast is also enabled when the Emergency Alert input* 2 is activated by the fire alarm system or other connected external equipment.)

[Alert announcement example* 3 ]

[Alert signal] Attention please. The fire alarm is indicating a fire.

We're now investigating the cause. Please wait for further information.

Alert signal and message

Step 2. Evacuation Broadcast

After the Alert broadcast has been repeated as pre-programmed, it automatically switches to the Evacuation broadcast, with an

Evacuation signal tone and a pre-recorded Evacuation announcement alternately broadcast to the entire zone.* 1

(The Evacuation broadcast is also enabled when the Emergency

Evacuation input* 2 is activated by the fire alarm system or other connected external equipment.)

[Evacuation announcement example* 4 ]

[Evacuation signal] There is a fire. Please evacuate as quick as possible.

Evacuation signal and message

Step 3. Live Microphone Announcement

(This announcement can be made during either Step 1 or Step 2.)

3-1. Holding down the Remote Microphone Talk key interrupts the current Emergency broadcast (Alert or

Evacuation broadcast), permitting broadcast of live microphone announcements to the entire zone.

Live microphone announcements

TALK key

3-2. The microphone announcement is terminated when the Talk key is released, and operation reverts to the Evacuation broadcast regardless of whether the microphone announcement was made during an

Alert or Evacuation broadcast.*

5

Note: In the Emergency Broadcast, the Talk key operates in the "press-to-talk" method regardless of its operation setting (by the RM-200M's function setting switch No. 4).

19

20

Step 4. Emergency Broadcast Termination

To terminate the Emergency broadcast, activate the Emergency Stop input by way of the corresponding connected external equipment. The unit returns to the general-purpose broadcast mode it was in immediately before the Emergency broadcast was started. Then, both EMERGENCY indicators of the RM-200M and the VM amplifier go out.

Note, however, that the unit does not return to the original general-purpose broadcast depending on the type of general-purpose broadcast. (See p. 21.)

Notes

• Emergency broadcasts are always made at the maximum volume level. The master and zone volume controls cannot be used during Emergency broadcast.

• Emergency broadcast cannot be terminated by the Remote Microphone.

• If emergency broadcast is stopped using the Reset key, the unit could not return to the mode it was last in before the emergency broadcast was activated.

• When the unit not equipped with the EV-200 is placed in emergency broadcast mode, announcements from the Remote Microphone can be broadcast over the entire area (by bypassing the attenuator). Press the

Remote Microphone's talk switch to make the announcement.

* 1 Requires installation of the optional EV-200 Voice Announcement Board.

* 2 A terminal built in the rear-mounted CONTROL I/O connector

* 3 Requires recording of the Alert signal, broadcast message, and their number of repetitions on an installed

CompactFlash (CF) card. (Consult the dealer from whom the unit was purchased.)

* 4 Requires recording of the Evacuation signal and broadcast message on an installed CompactFlash (CF) card. (Consult the dealer from whom the unit was purchased.)

* 5 The unit is placed in this operation mode when the internal function switch (SW3-3) is set to the factorypreset position. This switch can be used to switch the microphone to "silent" mode after announcement completion. (See p. 49 "VM Amplifier's Internal Function Switches.")

Note that this setting places the system in silent mode following a live microphone announcement, allowing further announcements to be made. Therefore, continuously repeat emergency announcements using the microphone to evacuate building occupants to safe locations.

[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. 45 "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.

Broadcast to be restored

Broadcast that is not activated by manual operation of or control from external equipment

• Broadcast from Inputs 1 – 3 not activated by control input (CTRL 1 – 3).

• Broadcast from BGM Inputs 1 and 2.

11. GENERAL-PURPOSE BROADCAST PRIORITY

11.1. Broadcast Source-to-Priority Relationship

• Making broadcast with higher priority cuts off the current lower-priority broadcast, allowing the higher priority broadcast to go through. Upon completion of the higher priority broadcast, the original broadcast is automatically restored. For background music (BGM) broadcast (Priority 4), it is also possible to mix it with other broadcasts or reduce its sound volume without cutting it off. (See p. 29 Priority Function during BGM

Broadcast.)

• Broadcast sound sources to which priority levels 1 – 3 are assigned in the table below can be set to any one of such priorities with the DIP switch (exception: Priority 3 for Inputs 1 – 3).

• Underlined priority levels represent factory-preset levels.

(ON position is for factory test.)

EV-200 surveillance signal output on-off (Switch No. 2)

Be sure to set to ON. (A 1 kHz signal output)

EV-200 surveillance signal output (Switch No. 2)

The EV-200 board always transmits a 1 kHz sine wave signal to an amplifier when the EV-200 Board is not reproducing audio signals. The amplifier detects the existence of the 1 kHz signal. When the signal does not exist, the amplifier judges the board's failure and causes the FAULT indicator to light.* (The signal indicating the EV-200's failure is transmitted from the CONTROL I/O connector.)

* If Switch No. 2 is set to the OFF position, the FAULT indicator lights even when the board is operating correctly.

27. COMPACTFLASH (CF) CARD RECORDING

27.1. Recording

• Use TOA's EV-350R Digital Announcer for CF card recording.

• The table below shows an example of Program/Sentence composition for Messages 1 – 8.

[Setting items and contents]

(1) Set the items in "Program No." (P001 – P008) and "Playback method" columns as shown in the table.

Besides, be sure to set the "Busy output (at repeat interval)" (omitted in the table) for ON (factory-preset).

(2) The contents in "Number of repeats", "Repeat interval", and "Sentence No. (or Silent Section)" are given for an example.

(3) Determine the optimum "Output level" for each Program by performing the operation.

(Factory-preset level: Graduation 6)

Note: The VM amplifier ignores the following settings programmed by the EV-350R.

(1) Program title, Sentence title

(2) Output (1 and/or 2)

(3) The setting contents to be registered in the EV-350R unit, not in the CF card. (See the item marked

(* 2 ) in the "Summarized Operational Functions" on page 15 of the "EV-350R OPERATING

INSTRUCTIONS.")

Refer to the "Digital Announcer EV-350R Operating Instructions" for terminologies and recording method.

[Usable CF Cards (their card adapter required)]

• Use the "SanDisk"* CompactFlash* (CF) card.

Required card capacity (16 - 96 MB) depends on the recording time and sound quality. For reference, see the card capacity vs. recording time table on page 8 of the "EV-350R OPERATING INSTRUCTIONS."

Be sure to keep 10-second or longer unrecorded portion on the card because it is used for controlling the

EV-200 board's surveillance function.

• Place the CF card in the CompactFlash card adapter, then insert the adapter into the memory card slot on the EV-350R's front panel.

* Trademark of SanDisk Corporation

Caution

• When the EV-200 is mounted, never move the unit from one place to another with the Flash Card inserted because the EV-200 or the CompactFlash card may fail.

• Avoid inserting or withdrawing the CompactFlash card while the unit is alive.
