Warnings and Precautions
Federal Communications Commission (FCC)
Compliance - This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. Further, proper installation does not guarantee that
interference will not occur in a particular situation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and affected receiver.
• Connect equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult an experienced radio/TV technician for help.
Radio Frequency Notice – The First InterComm™ System generates and uses RF energy. Changes or
modifications to the equipment may cause harmful interference unless the modifications are expressly
approved in the installation or maintenance manuals. The authority to operate the equipment could be
lost, if an unauthorized change or modification is made.
Electromagnetic Interference/Compatibility
Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately
desogmed. shielded, or otherwise configured for electromagnetic compatibility. It may be necessary to
conduct compatibility testing to determine if any electronic equipment used in or around vehicles is
sensitive to external RF energy or if any procedures need be applied to eliminate or mitigate the potential
for interaction between the First InterComm™ System and other equipment or devices.
• Facilities – To avoid EMI or compatibility conflicts, turn off the First InterComm™ System near any
facility where posted notices instruct you to do so; e.g., hospitals or health care facilities.
• Vehicles – To avoid possible interaction between First InterComm™ System and vehicle electronic
control modules (e.g., ABS, engine, or transmission controls), the First InterComm system should be
installed only by a professional installer.
• Pacemakers – Maintain a minimum separation of 12 inches between First InterComm™ System
components (the VCA100 and associated antennas) and any pacemaker to avoid potential
interference with pacemaker function.

EMC Installation Guidelines
The design and manufacture of the VCA100 conforms to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation is required to ensure that performance is not
compromised. Although every effort has been taken to ensure that it will perform under all conditions, it is
important to understand what factors could affect the operation of the product.
The guidelines given here describe the conditions for optimum EMC performance, but it is recognized
that it may not be possible to meet all of these conditions in all situations. To ensure the best possible
conditions for EMC performance within the constraints imposed by any vehicle, always ensure the
maximum separation possible between different items of electrical equipment.
For optimum EMC performance, it is recommended that wherever possible:
The equipment and cables connected to it are:
• At least 3 ft. (1 m) from any equipment transmitting or cables carrying radio signals
• The cables specified in this manual are used. Cutting and rejoining these cables can
compromise EMC performance and must be avoided.
• If a suppression ferrite is attached to a cable, this ferrite should not be removed.
• If the ferrite needs to be removed during installation it must be reassembled in the same
position.
General Precautions
• DC Power – Ensure that power into the First InterComm™ System does not exceed 24VDC.
• Explosive Environments – Ensure the First InterComm™ System is turned off before entering a
blasting area, or in areas posted “TURN OFF TWO-WAY RADIO”. Sparks in a potentially explosive

1.0 Introduction
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 included with 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 as 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) “Standard 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 installation guide contains information for the proper installation of the FICS. We
strongly recommended that the system be installed in accordance with this guide,
understanding that concessions may be needed for specific vehicles. This guide
assumes that the system installer is a qualified professional, familiar with the intended
vehicle, and possesses the proper tools.
2.0 First InterComm System™ Description
The FICS (Figure 1) consists of:
• VCA100 unit, matched to user’s existing radio network frequencies
• Vehicle-mounted Wireless Fidelity (Wi-Fi) antenna
• Land Mobile Radio (LMR) antenna, matched to user’s existing radio network
frequencies
• Remote On/Off switch
• Incident Commander Talkgroup Control Software (optional capability)

The system operates on 12VDC vehicle power through an independent cab-mounted
switch. There are no speakers, microphones, or other vehicle tie-ins.
Nine VCA100 models are available to cover the LMR bands (see Table 1). The LMR
antenna must match the frequency band of the VCA100 model being installed. A
standard, roof mounted 2.4 GHz 802.11 antenna is used for all VCA100 models.

3.3 System Component Locations
WARNING
WHEN SELECTING LOCATIONS FOR FIRST INTERCOMM COMPONENTS, AVOID HIGH
FREQUENCY (HF) NOISE PRODUCERS AND DO NOT RUN DC POWER FEEDS TO
THE VCA100 PARALLEL TO IGNITION CIRCUITS, ELECTRONIC MODULES, OR
SIMILAR ITEMS. AVOID RUNNING POWER LEADS IN PARALLEL WITH VEHICLE
WIRING OVER LONG DISTANCES.
3.3.1 VCA100
The VCA100 has no operator interfaces other than an activity indicator. Also, the unit
has no fan; it is convection cooled and does not require any special ventilation.
However, it is not environmentally sealed and must be installed in a protected area (THE
ENGINE COMPARTMENT IS NOT ACCEPTABLE). The optimum location is one in which the
VCA100 is out of the way, its face plate and cable connections protected as much as
possible, and there are at least six inches of space around the VCA100 to allow air
circulation.
Plan for cable management and strain relief loops for the cables. Cable ties and
mounts are needed to prevent cable movement and vibration.
3.3.2 WiFi Antenna
The WiFi antenna location has highest priority because the antenna’s relatively short
range has the greatest effect on system performance. Mount the antenna as high as
possible on the cab roof, and as close as possible to the vehicle’s centerline to provide
360-degree coverage. The antenna requires a metal ground plane to achieve its full
5dBi of gain.
We recommend keeping the antenna at least 12 inches away from any light bars or
other antennas and MUST be installed so as to provide a separation distance of at least
18 inches (45 cm) from all persons. The maximum designed distance from the VCA100
to the WiFi antenna is 17 feet, the standard cable length that comes with the antenna.
Extensions may be added to the cable, but this will reduce the WiFi range.
Certain vehicles do not allow locating the antenna in the center or center-rear of the
roof. In this case, the next best antenna location is on the direct center of the trunk lid.
The mounting area under the antenna must be a flat, metallized ground plane. Be
aware, however, that this location will degrade the WiFi range.

System Installation Guide
Page 8 A29799
November 2007
3.3.3 Land Mobile Radio Antenna
The LMR antenna must match the frequency of the specific VCA100 model being
installed on the vehicle. Ensure that the new LMR antenna is not installed in close
proximity to any existing LMR antennas.
We recommend keeping the antenna at least 12 inches away from any light bars,
antennas, or other roof-mounted equipment and MUST be installed so as to provide a
separation distance of at least 18 inches (45 cm) from all persons.
3.3.4 Power and Fuse
The vehicle’s main power source is connected to the VCA100 by the DC power cable
(red) that passes through an inline fuse. Locate the fuse as close as possible to the
power source and splice it in with weatherproof butt splices (SUPPLIED). Mount the fuse
assembly (Figure 5) to facilitate maintenance. Splice the power line to the VCA100
power harness (SUPPLIED) using the step-down splice (SUPPLIED) to accommodate the
dissimilar wire gauges.
Figure 5. In-Line Fuse
3.3.5 Manual Switch
A second, low current, power line (orange) must run through a cab-mounted manual
toggle switch to the VCA100 SENSE input (pin 2). This switch is not supplied in the
deliverable installation kit because User-specific vehicle installations vary; i.e., switch
location is a function of User requirements and vehicle constraints. An illuminated
manual switch, appropriately labeled, is recommended. Connect the switch to a
1-ampere fuse-protected vehicle power source.
