Fireground
The portable Fireground Communications System is
designed for deployment at an incident scene. It consists of
five central components:
• Your APX portable radios
• Incident Management Software
• Command Terminal
• Radio Frequency (RF) Modem (Conventional Only)
• Control Channel Radio (Trunking)
• Optional Data Radio (Trunking)
• Accountability Server (Trunking)
• DVRS (Optional)
These components provide on-scene and inbuilding radio
coverage, and enhanced personnel accountability and
monitoring.
The radio helps to indicate your presence on the scene if it
is in the range of the Incident Commander command
terminal, or trunking radio system.
Each Fireground Communication System radio
automatically reports your radio ID on the commander
mobile command terminal. Your name, riding position and
sector are all can be configured to be seen at the
Commander’s command terminal.
If you have a critical situation, you can press the
Emergency button which activates an alarm on the Incident
Management Software at the command terminal.
