VM-2240

VM-2240

The TOA System Management Amplifiers VM-2120 and VM-2240 are
expressly designed to fulfill increasing requirements for reliable and efficient
communications in mid-size facilities such as office buildings, factories,
hospitals, transportation terminals and many other sites. Both amplifiers are
multifunctional designs, with the VM-2120 rated at 120W and the VM-2240 at
240W. Each amplifier may be cascade-configured to meet increased power
demands. Conforming to EIA standards both amplifiers may be rack-mounted,
taking up just a 3-unit space.
A VM-2000 Series amplifier accepts six audio inputs which include two BGM
inputs and a telephone paging input. Speaker output selector for five zones is
provided as well as an internal speaker attenuator. In addition to generalpurpose
broadcasts, EN60849* standard-based emergency broadcasts which
may be pre-recorded*1 or transmitted via the optional RM-200M Remote
Microphone are possible. These operations can also be remotely controlled
using external auxiliary equipment.
A VM-2000 Series amplifier is also equipped with surveillance capability*2 that
conducts automatic system checks for malfunctions.
* EN denotes European Standard
*1 requires optional EV-200M Announcement Board.
*2 requires optional SV-200MA Surveillance Board.
Remote Microphone RM-200M
May be connected to either amplifier to provide general purpose and
emergency broadcasts.
Remote Microphone Extension RM-210
Facilitating communications as an extension unit for controlling key system
operations.
INTEGRATED VOICE EVACUATION SYSTEM

A VM-2000 Series amplifier can be combined to increase its system
coverage number of speaker zones.
Use of the optional SV-200MA 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-200M 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
o peration 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.
