How ITC PA & VA System Used for Transportation System?

3. Successful Project Reference Worldwide-Botswana Airport in South Africa
The airport is situated in the second
biggest city of Botswana, South
Africa and the schedule of flights is
done is such a way that a business
person can arrive in the morning
doing his business and take off in
the evening.
 ITC had supplied digital voice evavuation system in this airport for background music system, airline
life speech system and fire emergency voice evacuation system.
 The VA-2000MA voice evacuation system offer a perfect PA & VA solution for airport, all of the design
are strictly accordingly to the lasted Fire Alarm System Regulation.
 It will be step for us enter the African market, however, we believe this start will bring us more
confidence.
 The system could supervise microphone failure, amplifier failure, system controller failure, speaker
line failure, AC failure and amplifier failure, which will offer a most secured solution for very strict
reliable system request.
 A complete range of fire-proof and explosion-proof speaker are equipped with the system.
 Versatile 22 channel inputs and 48 zones audio matrix, flexible module system, remote LAN
maintenaince, high capacity zone management, live announcement, fireman voice evacuation, 4
evacuation message simultaneous broadcasting, 4 commercial message, contact in and output to
inter-work with third party system, less equipment and less power comsumption.

4. Successful Project Reference Worldwide-Tehran Metro Station in Iran
 The Tehran Metro is a rapid transit system serving
Tehran, the capital of Iran. The system consists of four
operational lines, with construction begun on a further
two lines in 2007.
 The Tehran Metro carries more than 2 million
passengers a day.[6] In 2010, 459 million trips were
made on Tehran Metro.
 The line 4 will be 20 km (12 mi) long with 22 stations
and one terminal. Section 1, from Ferdowsi Square to
Darvazeh Shemiran, opened in March 2007. Section 2
from Darvazeh shemiran to Shohada Square opened in
February 2009. On May 24, 2009, Section 3 from
Ferdowsi Square to Engelab Square opened. On July
23, 2012 two more stations were inaugurated,
connecting line 4 with line 5.
 ITC's digital IP addressable network audio system and
intercom system were successfully installed in the Tehran
Metro Line 4 in 2009.
 The system construction concept is to offer background music
system in waiting room and line passenger information system
and fire emergency voice evacuation system. After a two
years tender bidding, ITC was rewarded the system by
seamless integration with Simens low voltage system and
control system.
 The digital IP PA & VA system is built up over network audio
through fiber optical cable, thus the system can cover the
whole line, the system could be centralized managed in
control room or in the metro itself, the system can
communicate with each zone flexiblely.
 The system is a full security system, a backup system will be
in standby when any equipment failure occured.

5.  The Beijing–Tianjin Intercity Railway is a high-speed rail, passenger-only line between
Beijing and Tianjin in China. The 117 km line was built to accommodate trains
traveling at a maximum speed of 350 km/h (217 mph), and currently carries CRH
high-speed trains running speeds up to 330 km/h (205 mph). When the line opened on
August 1, 2008, it set the record for the fastest conventional train service in the world
by top speed, and reduced travel time between the two largest cities in northern China
from 70 to 30 minutes
 Our ITC Network audio system had been successfully installed to manage and control
the background music system and deliver network speech or paging system to every
stop and digital voice evacuation system for security and fire alarm use.
