Welcome to First InterComm™ Networking
The First InterComm™ System (FICS) 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 FICS can accommodate any new communication technologies,
including the 700-MHz bandwidth.
Only one vehicle from each on-scene department is required to have an installed FICS
unit to enable linking dissimilar radio networks. There is no requirement for special
equipment, stand-alone towers, or other costly infrastructure.
An optional capability of the FICS is the Incident Commander Talkgroup Control™
Software (ICTCS) that allows the Incident Commander (IC), using a standard laptop
computer with Wireless Fidelity (Wi-Fi) capability, to monitor system status and to
control communications. The ICTCS significantly enhances the system, but is not
required for voice interoperability; the latter is provided by the VCA100 and associated
antennas alone.
The Department of Homeland Security (DHS) has designated the FICS a “Qualified
Anti-Terrorism Technology” under the SAFETY Act. The FICS Supports the National
Incident Management System (NIMS), and is included in the Memorial Institute for the
Prevention of Terrorism (MIPT) “Responder Knowledge Base” and the InterAgency
Board's (IAB) “Standardized Equipment List” (SEL).
Finally, it is important to note that using the FICS does not require changes to your
Standard Operating Procedures (SOP). Rather, it provides day-to-day voice
interoperability at an incident scene, and offers improved coordination of on-site first
responder personnel.
This User Guide contains a description of the FICS, and information on how to activate
the system and maximize its effectiveness.
First InterComm™ System Overview
The FICS consists of a Vehicle Communications Assembly (VCA100), a Land Mobile
Radio (LMR) antenna, and a Wi-Fi antenna. The system uses standard 12 VDC vehicle
power and has these features:
• No setup time required; voice interoperability is automatically available within one
minute of arriving on scene;
• Responders use their existing familiar radios. Multiple radios are not required;
• Responders require no special training;
• System span is scalable from routine to large incidents with no change in SOP;
• Compliance with commercial standards for radio communications and mesh
networks;
First InterComm
™
System User Guide
Page 2 A29798
November 2007
• Connectivity with civil and military communications Systems; and
• Digital technology which supports radio upgrades.
The optional Incident Commander Talkgroup Control Software (ICTCS gives the
Incident Commander the option to monitor VCA100 status and control communications
using a standard laptop computer with Wi-Fi capability.
NOTE
THE ICTCS ADDS SIGNIFICANT CAPABILITY TO THE SYSTEM, BUT IS
NOT REQUIRED FOR VOICE INTEROPERABILITY WHICH IS PROVIDED BY
THE VCA100S AND ASSOCIATED ANTENNAS.
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 Group A first responder, whose radio operates at
453.95 MHz, is talking to a Group B first responder whose radio operates at 154.57
MHz. The process that makes this happen is as follows: When a Group A portable or
mobile radio is keyed up, its voice transmission is translated into digital Voice-over-
Internet Protocol (VoIP) packets that are placed onto the IAN. Every VCA100 unit
registered in the network (in Figure 1, Group B) receives these digital packets, which
are then translated back into voice transmissions compatible with each frequency
associated with the receiving VCA100.

Figure 1. The FICS in Action
As other first responder departments arrive on scene and turn on their VCA100s, the
units automatically connect to one another. When local first responders are joined by
other agencies (e.g., Public Health, Disaster Recovery, Federal Agencies, and National
Guard), their VCA100 units also connect to the IAN, thus establishing cross-

jurisdictional communications. 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 (IAN) Expands or Contracts as Needed
At some point, when numerous first responders are on-line, overall coordination can be
beneficial. The IC has the OPTION to assume control of the IAN using any laptop
computer operating with Windows XP and equipped with Wi-Fi and ICTCS (Figure 3).
The ICTCS allows the IC to:
• Establish sectors by frequency in accordance with the DHS National Incident
Management System (NIMS);
• Isolate any agency equipped with FICS units (e.g., Fire, EMS, Emergency
Management, Public Works, law enforcement) as required into the appropriate
Talkgroup, thereby
» Ensuring a single chain of command;
» Improving communications efficiency; and
» 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 selected for use with the VCA100.
4. Communicate using the applicable SOP.
RECOMMENDATION
TURN ON THE VCA100 UNIT ON THE WAY TO THE SCENE
Vehicle Location
Wireless signals grow weaker as they propagate (travel away) from the transmitter. The
FICS is designed to operate up to approximately one-quarter mile between VCA100s,
assuming a clear, unobstructed Line of Sight (LOS). Buildings, hills, vegetation, and
other obstructions will reduce range as shown in Figure 4. In addition, metallic objects
such as dumpsters, vehicles, etc. may cause interference that degrades performance. If
possible, position VCA100-equipped vehicles to minimize such factors.

Signal Relay (Hopping)
Figure 5 shows a generalized urban incident site where there is no LOS between
vehicles A and D or vehicles B and C. Figure 6 shows a generalized ex-urban incident
site where vehicles A and E have no LOS and are considerably farther apart than one-
quarter mile. In both scenarios, the FICS overcomes these limitations 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 FICS appears to interfere with incident site operations,
immediately turn off every VCA unit (and ICTCS if in use) and return to
normal operating procedures.
• If ICTCS or laptop computer problems occur, the VCA100 units will
remain in their assigned Talkgroups. If the laptop or ICTCS is not
functional, and communication is needed between all responders,
cycle power to all VCA100s. This entails turning off the power to the
VCA100 and then re-powering.
Table 1. VCA100 Troubleshooting Procedures
Problem Action Comments
