MS-900 Master Station
Creating today's ideal security.
Security in various environments is more essential than ever. From office
buildings to shopping malls, airports, car parks and garages to institutional
facilities such as schools and college campuses, hospitals and medical centers,
industrial and correctional facilities to hotel and high rise residential buildings to
senior citizen homes —the list grows daily while the reason stays the same —
to ensure security and time-critical communications on a 24/7 basis.
TOA technology can protect lives and property, maintain health and safety
as well as enhance organizational efficiency and productivity.
TOA uses its accumulated expertise and knowledge gained over a half century
plus in sound and public address, security and surveillance (CCTV) technologies
to offer cost-effective and totally dependable solutions that fulfill all your
communication and security requirements to always keep you "Safe & Sound."

Voice Security
Intercom System.
The VS-900 represents significant
value for any security system. Its
comprehensive audio capabilities
including an advanced voice
communications system integrate
seamlessly with existing security and
video surveillance systems to provide
a significantly higher level of security
for you.
System features
Manage the system from on- and
off-site locations.
Through the built-in industry-standard
RS-232C port, the VS-900 can be conve-
niently programmed and administered from
any location, even offsite via modem. System
software can also be easily upgraded,
increasing the operational and service life of
the system and overall functionality.
Useful data logging.
The VS-900 is equipped with a second
RS-232C port that connects to a computer so
that events can be automatically logged at
each exchange.
Efficient voice recording.
At each master station, the VS-900 enables
automatic recording of calls that provide a
useful record for post-event analyses. Each
telephone line* can also be assigned for
individual recording outputs.
Designed to suit your particular
environment.
The VS-900 has been designed with system
flexibility in mind. The fully scalable architec-
ture can be precisely tailored to your existing
system and expanded right along with your
environment's requirements. And because the
VS-900 mainframe employs an all-modular
construction, it simplifies installation proce-
dures as well as routine maintenance. System
expansion options can easily be incorporated
using interface and function cards. The fully
modular configuration eliminates system
obsolescence and ensures you get always
the most from your investment. The VS-900
exchange can also be rack or wall-mounted
to minimize space requirements.
System expands as required.
Up to four master stations and up to 64
substations can be connected to each
VS-900 exchange. An exchange will also
accommodate two outside telephone lines*
as well as a dedi-cated computer interface.
To satisfy system demands for even large
institutions, a tie-line capability enables
connecting up to 16 exchanges with 64
master stations and up to 1,024 substations.
*use dependent on individual country telephone regulatory
codes.

System Applications
Protection and security.
At any site, all controlled-access points such
as doors and parking gates benefit from two-
way communication features provided by the
VS-900. And by interfacing with CCTV
systems such as TOA's, video combines with
audio to achieve total monitoring. Used
together with access control, other functions
such as opening doors and gates as well as
controlling surveillance cameras are easily
performed. For alerting personnel, the VS-900
will also transmit warnings to substations.
Selective scan monitoring.
This allows any master station to selectively
scan a group of substations for realtime audio
monitoring. This feature is significantly
enhanced when used in combination with
CCTV surveillance to assure a higher level of
security as it combines audio and visual
monitoring capabilities.
Versatile call handling.
The VS-900 receives environment-wide
emergency calls from any substation at a
central security control room. The VS-900 can
forward calls manually or automatically to any
master station onsite or offsite telephones.
Times can be set for the system to automati-
cally forward calls, useful during personnel
shift changes and to maintain good communi-
cations during slack times or off-hours security.
No-Answer Call Forwarding and Busy Call
Forwarding modes are also available. Calls
can be also be transmitted to outside tele-
phones and mobile phones as well as pagers
for notification. Many more helpful features are
offered such as group calling, autodial and
redial, call transfer/hold, call priority for normal/
emergency calls, automatic call timeout, call
queuing, and selective response.
Convenient conference calling.
The VS-900 enables master stations to easily
initiate three party conference calls even in
the middle of a two party conversation for
instance when a consultation is needed with
a person on- or offsite. An Emergency
Conference feature for up to four parties is
also provided.
Multi-functional paging.
The VS-900 system provides four paging
methods:
•Zone paging broadcasts to selected zones
•Simultaneous all-zone paging broadcasts
•Emergency paging broadcast to entire areas
•External sound source distribution to
individual zones activating a sound source
such as a chime.
Each substation's built-in speaker may be
used if driven by an external amplifier*.
Up to 19 paging zones can be established by
combining multiple substations with external
public address system even the most remote
areas of a site can be covered efficiently.
*TOA A-1031 or similar amplifier. Matching transformer such
as the TOA MT-502U needed. (Part Number 514-04-013-20)
Note: All telephonic and related communications functions use described above dependent on individual country regulatory codes.
Substations designed for any
installation.
TOA offers a range of substations for specific
installation conditions. Featuring a rugged
design for reliability, each substation provides
a speaker and call button. One design
includes a call lamp as well. For areas such
as parking lots and remote locations, there
are tough vandal-proof and weather-resistant
substation models. In an emergency, any
substation can be instantly activated by a
single button —practical as emergency or
crisis situations tend to
confuse people.
TOA's audio expertise
maintains superlative
clarity in call quality to
eliminate possible
misunderstanding.
*Vandal-proof versions feature a stainless front panel that is 1.5 times thicker than the RS-150's panel.
The internal speaker is protected by a metal plate.
