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 EIAStandard 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 RM200M Remote Microphone as well as from the amplifier, and can be remotely controlled from external
equipment. In addition, both amplifiers feature the surveillance function*2which automatically checks the
system for failures.
*1An 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.
• Never connect the AC power cord to any other line voltage than that specifically designated.
• To avoid oscillation, keep the input cable away from the output cable. Particular care must be exercised
when mounting the unit in an equipment rack.
• In some installations, a ground loop is formed and hum noise may be generated. In such cases, connecting
the rear-mounted signal earth terminal to the body of connected equipment (BGM sound source, expansion
amplifier, etc.) may reduce it.
• Never connect two amplifier outputs in parallel under any circumstances.

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.
A pre-recorded Alert signal tone and Alert announcement will be
alternately broadcast to the entire zone for the preset number of
repetitions.*1The 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*2is 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.
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*2is 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.
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.
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).

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.
*1Requires installation of the optional EV-200 Voice Announcement Board.
*2A terminal built in the rear-mounted CONTROL I/O connector
*3Requires 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.)
*4Requires recording of the Evacuation signal and broadcast message on an installed CompactFlash (CF)
card. (Consult the dealer from whom the unit was purchased.)
*5The unit is placed in this operation mode when the internal function switch (SW3-3) is set to the factory-
preset 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.
