Study Notes

LAFD Communications Protocols

LAFD channels can operate in direct or repeat mode depending on frequency assignment.
Mutual aid 8TAC channels function in both direct and repeat modes, but with limited capabilities in repeat mode.
Only one 8TAC channel can be used per repeater site to avoid interference, e.g., 8TAC91 SPH and 8TAC91 VPK cannot be used simultaneously.

Tactical Area Operations

Upon tactical area activation, the MFC switches to the Fallback Communications Plan (FCP) relevant to the affected Bureau.
Additional frequencies are provided for dispatch, with Operations Central Bureau (OCB) using LFD T-1 inside tactical alert areas and Channel 7 outside those areas.
MFC can transfer dispatch responsibility to Area Command for incidents within tactical alert areas and release specific frequencies for their use (Channels 1, 2, 3, or 13).

Incident Commander Communication

Incident Commanders must use tactical channels assigned to the Area Command for their incident, primarily in direct mode.
Operations South, Valley, and West Bureaus share tactical frequencies to enhance communication distance and minimize interference.
Communication between Incident Commanders and Area Command occurs on Bureau Command frequency, using Channel 11 for inter-Area Command communications.

Radio Identification and Non-Operational Status

Members with cache or non-assigned radios should notify MFC for proper FCC radio identification programming.
No emergency trigger capability is available if MFC is non-operational.

Bureau/Area Communications Unit Structure

Each Area Command Post has a communications unit leader and emergency communicators primarily responsible for relaying radio traffic.
This unit supports any Battalion Communications Unit that fails to activate.

Auxiliary Communication Services (ACS)

When the radio system malfunctions, amateur radio operators can relay vital information (Mode-4).
Amateur operators respond to specified MFC zones, Area Command Posts, and a Mobile Radio Command Trailer.
The amateur radio program operates under the Fire Department's supervision, adhering to California's CalOES regulations.

Dispatch Modes Overview

Mode-1: Implemented when normal channels are overwhelmed; MFC decentralizes dispatching into four channels and enhances capability using available talk groups and mutual-aid channels.
Effective Example: Mode-1 saw success during the 2020 Safe LA Protest, allowing enhanced communication management.
Mode-2: Activated when 9-site voice repeater systems fail but backup systems remain operational; may result in reduced voice performance, especially in South and West Bureaus.
Mode-3: Initiated when Mutual Aid repeaters function at only two sites (San Pedro and Verdugo) and normal dispatch capabilities are compromised; designated mutual aid channels are used for dispatching.
