The TOA VS-900 SECURITY INTERCOM SYSTEM
provides reliable and intelligible voice communication
for critical security applications, including corporate
security,correctional institutions,educational facilities,
hospital access points, and parking structures. For
over 35 years,TOA has developed a proven track
record of innovative, reliable intercom products,
including the groundbreaking EXES and IC-100 systems.
The TOA VS-900 system is UL and CUL Listed and
manufactured to ISO-9001 standards to ensure
continuous operation for extended periods.
Ideal for applications with multiple "sub"stations
calling in to one or more "master"stations, the VS-900
has a wide range of standard and software pro-
grammable features, including comprehensive Call-
Forwarding to allow system operators freedom of
movement and most importantly, to ensure that no
calls go unanswered. The VS-900 integrates easily
with access control and video surveillance equip-
ment via a simple RS-232 communications protocol.
Other features include telephone system integration,
paging and external source distribution, event log-
ging, and recording outputs.
The VS-900 scalable architecture allows the most
cost effective configuration for each application
with easy expansion as the size of the facility grows.
Each exchange mainframe supports up to 4 master
stations and 64 sub-stations. For large systems,
exchanges can be expanded or "tie-lined"to provide
up to 64 master stations and 1,024 sub-stations. The
master stations can be either the TOA MS-900 or standard
off-the-shelf single line telephones with support for
Caller-ID signaling. Sub-stations include Economy,
Indoor, Outdoor, and Panic models, each with heavy-
duty plate, call switch and optional LED/relay control.
Direct select interface cards provide relays,LED drivers
and switch inputs for custom consoles and annunci-
ator panels.
The VS-900 Security Intercom System is backed with
a two-year warranty.
