Rocket Launch Facility - Airport -
Manufacturing - Military/Government -
A rocket launch facility at Cape Canaveral is a
challenging environment for a public address system. Three
locations, separated by miles of snake and alligator-infested landscape,
must be served. Several access sources with different levels of
priority must be accommodated. Outdoor areas more than a quarter
mile away from horn loudspeakers must be covered. Few places on
earth are subject to the environmental extremes of a rocket blasting off
The public address system for one such facility
provides paging, signaling and audio distribution using state-of-the-art
digital technology. Valcom
Voice over IP (VoIP) provides the communication links
between the Operations Center, the Vertical Integration Facility (where
the rocket is assembled and loaded), and the Launch Pad. The VCS Communication
System is the central control.
The microprocessor-controlled, PC-programmable
with remote programming and diagnostics capabilities, provides multiple
talk paths. Employing state-of-the-art digital technology, it
connects to both centrally amplified (70-volt) and distributed amplified
(24-volt) components, with expansion capabilities for 360 zones, 7
inputs, and eight talkpaths.
An Airport Crash Phone System is an integral part
of the Emergency Communications at an airport.
By lifting the handset of a dedicated telephone, it provides
ringdown, conference and broadcast announcement to first responders at
multiple locations in the event of an emergency.
A large Southwestern International Airport needed
to update their aging Aircraft Rescue and Fire Fighting (ARFF) Crash
Phone System with additional features.
They required additional origination and 2 way conference points,
system fault monitoring and a special function tone to be heard over
crash phone handsets and public address speakers.
This tone verified that all required parties were off-hook on the
conference. One of the required
parties was staffed only from 6AM to midnight so the system had to be
programmed for their exception to the system from midnight to 6AM.
Valcom Services designed and provided a Valcom VoIP
solution that connects the Airport Tower, ARFF Fire Station, Harbor
Police, County Emergency Response Center, Remote Ramp and Terminal areas
with expansion capability for future locations.
System activity and fault monitoring is provided by Syslog
messages to an airport Syslog Server.
An additional panel in the main rack provides audible and visual
indication of a network problem. The system interfaced with new and
existing red analog crash telephones and the relay controls at the ARFF
for activating bay doors, lights, etc.
The system was installed in parallel with the old system so that
cutover time was minimal.
A large Midwest manufacturing facility needed ways
to increase productivity in order fulfillment. The work flow was
being interrupted when employees ran out of product. They needed a
way to be re-supplied quickly, which required better communication
between order fulfillment and stockroom employees. Valcom Services
designed a system that allowed order fulfillment to signal when stock
ran low. Signaling provided a digital readout that identified the
employee's location and opened an immediate handsfree communications
channel allowing verbal instruction as to what product was needed.
The system could be reprogrammed instantly from a PC when necessary.
The system provided 288 communication paths
between employees and operators. Special speakers hung from
chains—adjustable to height—were installed over the conveyor belts.
The system also provided background music, with programming chosen daily
by the employees.
When it comes to paging, military bases are full of
challenges. They are spread over many buildings, and need lots of zones.
They need coverage to many large outdoor areas. They need the ability to
broadcast paging, signal tones, and prerecorded announcements. They must
be able to send different messages to different zones simultaneously,
without interrupting broadcasts in other zones. They are highly secure,
and must be fail safe in an emergency.
Valcom Services met all these challenges, and
others, at an Air Force Base in the western US.
A legacy Valcom paging system installed in 1985 was
extended to more than 50 buildings, using fiber optic cable that had
recently been installed between the buildings. Horns on the base
perimeter were tied into the system also. The final configuration
included hundreds of speakers and horns, and more than 200 zones.
The Valcom VCS Communication
System was installed as the
system central control. The modular, microprocessor-controlled VCS can
be expanded to 360 zones, and is programmable (on site or remotely) with
a PC. It has a serial output for system activity reporting, so that
system traffic information can be used to make updates and changes
In big city
hospitals, things change with incredible speed.
Keeping up with the changes can be overwhelming, and a hospital
values any tool that makes it easier.
At a large hospital in
Houston, the paging system can be updated with a few mouse clicks on a
PC. Zones, group zones,
priorities, alert tones, music programs and several other functions can
be changed in an instant by trained hospital personnel.
Programming can also be done remotely.
System controls more than 2000
speakers on dozens of zones.
It can also control desktop administrative stations and digital visual
message displays. All wire
runs are electronically monitored, so there is never a danger that an
emergency message will not be heard.
A wire break or short triggers an alarm on a digital display that
identifies the area of trouble.
microprocessor-controlled VCS provides both one way and talkback paging
in up to 360 zones. Multiple
announcements (live or pre-recorded) can be broadcast to different zones
simultaneously, without interrupting signal tones or music broadcasts in
