First InterComm™ system VCA100 user manual A29798 September 2008 1Welcome to First InterComm™ systemprovided 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.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 First InterComm system overview– 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.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.NOTE– Talk Group software provides significant capability to the First InterComm system but is not required for voice interoperability.

2First InterComm™ system VCA100 user manual A29798 September 2008Turning 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.The First InterComm system in actionFigure 1.

First InterComm™ system VCA100 user manual A29798 September 2008 3Figure 2. The incident area network expands or contracts as neededAs 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.
