VOICE SECURITY

INTERCOM SYSTEM

VS-900 SERIES

DESCRIPTION

TOA's VS-900 is a security communications system specially
designed for applications in such facilities as office buildings,
factories, schools, hospitals, and prisons. Installed separately
from conventional general-purpose internal communications
systems, the VS-900 can be used to access control or make
urgent calls in emergency situations.
The system is comprised of a central exchange and remote
stations, and permits calls to master stations located in the
central control room or in facility guard rooms from substations
installed in such varied locations as entrance gates, parking lots
or building entrances.
The exchange itself features modular construction that permits
easy customization to fit the desired scale and application, and
later meet changing customer needs by simply plugging in the
corresponding cards. Up to 4 master stations and 64
substations can be connected per exchange, and the system
can be expanded to up to 64 master stations and 1,024
substations through the tie-line connection of up to 16
exchanges.
A standard personal computer can also be connected to the
exchange to provide convenient adjustment of system setting
functions and automatic logging of communication operations.
A full range of exchange functions other than basic
conversation are also featured, including call forwarding, scan
monitoring, emergency conference, conversation recording by
way of external equipment, and paging by way of an external
amplifier.
There are five different types of substations, including those of
indoor-use, outdoor-use, and vandal-resistant types.
The VS-900 can also be used in combination with CCTV,
access control, emergency broadcast systems or other security
equipment to create a more effective security system and
ensure a higher level of safety and security in each facility.

PC INTERFACE SOFTWARE

DESCRIPTION

Conversation and broadcasting functions can only be used by
programming individual line assignments for each facility, station
numbering schedules, function details and other data into the
exchange before the system is actually used. To perform such
settings, a personal computer loaded with dedicated software
needs to be connected to the exchange. This dedicated software
enables general control and maintenance settings as well as
system programming functions.

Notes

Some functions to be registered at master stations cannot be enabled without prior
system programming.

SYSTEM REQUIREMENTS
