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 high-
performance built-in compression circuit.
