First InterComm™ system VCA100 user manual A29798 September 2008
Welcome to First InterComm™ system
The First InterComm system allows first
responders from different agencies
at an emergency incident to readily
communicate with one another,
even though their radios operate on
different frequencies (i.e., VHF, UHF
or 800 MHz systems, both digital
and analog). The First InterComm
system can accommodate many newer
communication technologies such as
radio systems operating in the 700-MHz
band, and P25-compliant equipment.
Only one vehicle from each on-scene
department is required to have a First
InterComm system installed to enable
linking of dissimilar radio networks.
There is no requirement for special
equipment, stand-alone towers, or other
costly infrastructure.
Talk Group software, an optional
capability included with the First
InterComm system, enables the
incident commander, using a standard
laptop computer with wired or wireless
networking capability, to monitor system
status and control communications. Talk
Group significantly enhances the First
InterComm system, but is not required
for voice interoperability; the latter is
provided by the VCA100 and associated
antennas alone.
The U.S. Department of Homeland
Security has designated the First
InterComm system as a Qualified
Anti-Terrorism Technology under the
SAFETY Act. The First InterComm
system supports the National Incident
Management System (NIMS) and is
included in the Memorial Institute for the
Prevention of Terrorism “Responders
Knowledge Base” and the InterAgency
Board's Standard Equipment List and
Approved Equipment List.
The First InterComm system enables
the responding departments to
operate within their SOP. It provides
day-to-day voice interoperability at an
incident scene and provides improved
coordination of on-site first-responder
personnel.
This user manual contains a description
of the First InterComm system and
activation information to maximize its
effectiveness.
First InterComm system overview
The First InterComm system consists
of a Vehicle Communications Assembly
(VCA100), a land mobile radio antenna,
and a wireless antenna. Using standard
12-Vdc vehicle power the systems
provides these features:
– No setup time required; voice
interoperability is automatically
available within one minute of arriving
on scene.
– Responders use their existing radios;
multiple radios are not required.
– Responders require minimal training.
– Scalable from routine to large
incidents.
– Compliant with commercial standards
for radio communications and mesh
networks.
– Provides connectivity with civil and
military communications systems.
– Compatible with digital technology,
supporting radio system upgrades.
NOTE
– Talk Group software provides
significant capability to the First
InterComm system but is not
required for voice interoperability.

First InterComm™ system VCA100 user manual A29798 September 2008
The First InterComm system in action
Turning on two or more VCA100 units
establishes an ad hoc wireless mesh
incident area network (IAN). In Figure 1,
the fire department, whose radios
operate at 154.57 MHz, is talking to
the police department, whose radios
operate at 452.95 MHz. When a
portable or mobile radio is keyed up,
its voice transmission is translated
into digital packets that are placed
onto the IAN. Every VCA100 unit on
the First InterComm network receives
these digital packets, which are
translated back into voice transmissions
compatible with each handheld radio
associated with the receiving VCA100.

First InterComm™ system VCA100 user manual A29798 September 2008
As first responders arrive on scene
and activate their VCA100s, the units
automatically connect to one another.
As the first responders are joined by
other agencies (e.g., public health,
disaster recovery, federal agencies,
National Guard), their VCA100 units
connect to the IAN, thus establishing
cross-jurisdictional communication.
This temporary IAN (Figure 2) exists as
long as VCA100-equipped vehicles are
present and can expand or contract as
first responders enter or leave the area.
Figure 2. The incident area network expands or contracts as needed
4
First InterComm™ system VCA100 user manual A29798 September 2008
As numerous first responders are
online, overall coordination is essential.
The incident commander can assume
control of the IAN via any laptop
computer operating with the Windows
XP®1 operating system with Service
Pack 2 and equipped with wired or
wireless networking capability and First
InterComm Talk Group software
(Figure 3). The Talk Group allows the
incident commander to:
– Establish sectors by frequency in
accordance with NIMS.
– Isolate any agency equipped with
First InterComm units (e.g., fire, EMS,
emergency management, public
works, law enforcement) into the
appropriate talk groups, thereby:
– Supporting a chain of command.
– Improving communications
efficiency.
– Increasing emergency responder
safety.

Operating the First InterComm system
Start-up
1. Apply power to the VCA100 with the
cab-mounted switch.
2. Allow approximately one minute for
the unit to initialize and connect to
any other VCA100s in the area.
3. Switch radio equipment to the tactical
channel on portable radio designated
for First InterComm system
interoperability.
4. Communicate using the applicable SOP.
RECOMMENDATION
Do not turn on the VCA100 unit until parked at the scene.
Vehicle location
Wireless signals weaken as they
travel away from the transmitter. The
First InterComm system operates up
to a quarter mile between VCA100s,
assuming a clear, unobstructed LOS.
Buildings, hills, vegetation and other
obstructions will reduce range as
shown in Figure 4. Interference from
metallic objects such as large trash
receptacles and vehicles can degrade
performance. Whenever possible,
position VCA100-equipped vehicles to
minimize such factors.

Figure 5 shows a generalized urban
incident site where there is no LOS
between vehicles A and B. Figure
6 showshow positioning vehicle C
enables the First InterComm system to
overcome these obstacles by “hopping”
voice communications (i.e., passing
communications through the units
that do have LOS). Thus, all units can
communicate even though not all have
direct LOS.

Troubleshooting
IMPORTANT
– If the First InterComm system appears to interfere with incident site
operations, immediately turn off every VCA100 unit and Talk Group software in
use and return to normal operating procedures.
– If Talk Group software or laptop computer problems occur, the VCA100 units
will remain in their assigned talk groups. If the laptop or Talk Group software
is not functional and communication is needed among all responders, cycle
power to all VCA100s. This entails turning off the power to the VCA100 and
then repowering.

The VCA100 unit (Figure 7) is vehiclemounted and has no operator controls
other than a remote power-on switch. Once
the VCA100 is initialized, operations are
transparent to the operator, responders
need only set their radio equipment to the
pre-designated interoperability channel
to monitor or speak to members of other
radio networks at the site. The specific
VCA100 model is based on the radio
frequencies used by the participating
department (see Appendix A).
