    Study Notes

    Radio Communication Terms

    • MOVE-UP: Computer prompts dispatcher to dispatch next available unit to cover other districts when all apparatus are committed to emergency incidents.
    • Negative: Response meaning "no" or "not available".
    • On the scene: Arrived at dispatched call.
    • Out-of-service: Not available for calls.
    • "Use Barrier Precaution": Units responding to incidents with infectious diseases should use barrier precautions; includes Tuberculosis, Meningitis, Septic, HIV, or skin diseases.

    Radio Signatures

    • Company officers and acting officers: Assume radio signature of unit number (e.g., Engine 21, Tower 22).
    • Drivers: Assume radio signature of unit plus DRIVER (e.g., Engine 21 DRIVER, Tower 22 DRIVER).
    • #3 jump seat position: Assume radio signature of unit plus JUMP (e.g., Engine 21 JUMP, Tower 22 JUMP).
    • Additional firefighters: Assume radio signature of unit plus JUMP 2, JUMP 3, etc.
    • Staff officers and others: Use assigned radio signatures (e.g., U22, TRT24).

    Aerial Platform Basket/Ladder

    • Aerial operation: Firefighter operating aerial assumes radio signature of vehicle plus TURNTABLE (e.g., Tower 22 TURNTABLE).
    • 800MHz frequency radio: Used when status keys are not available and voice transmissions are necessary.

    Dispatch and Response

    • Lead equipment notifies Central of group in-service when responding from a station.
    • Equipment responding from a location other than quarters notifies Central of approximate location.
    • Central acknowledges responding units and incident nature; supplemental information can be given after this transmission (called a "readback").
    • Dispatcher corrects incorrect information repeated by Fire personnel.

    Communication Process

    • Unit to be called is stated first, followed by the unit initiating the call.
    • Wait for a "go-ahead" to transmit a message after a voice transmission.

    Fire Dispatch and Fireground Talk Groups

    • Fire Dispatch (FD3) talk group: Located in position 1 and 16 on all digital portable radios; used for emergency and non-emergency incident dispatches.
    • Hoffman Estates Fire Ground (HFES FG) talk group: Located in position 2 and 15; used for fireground operations and incidents with heavy radio traffic.
    • Schaumburg Fireground talk group: Located in position 3; used for fireground operations and incidents with heavy radio traffic.
    • Fireground Red talk group: Located in position 4; used for fireground operations and incidents with heavy radio traffic.
    • NWC Fireground 3 talk group: Located in position 5; used for fireground operations and incidents with heavy radio traffic.
