los angeles city fire department radio procedures

[agent yo'range]

lafd radio procedures go something like this

simple overview is - ch 7 for metro fire units - ch 4 for metro ems
units - ch 8 for valley units - these are the 3 main channels

=======================

for more details

https://www.radioreference.com/db/subcat/248 - list of radio channels at rrdb

units that are located in a fire station are dispatched by teleprinter
or public address or some fixed system like that - or maybe via the
mdt in the rig

units that are not in a fire station are dispatched verbally via Ch 4 or 7 or 8

calls are also dispatched via MDT and acknowledged via MDT

most minor calls are announced once quickly verbally on ch 7 or ch 8 -
possibly some ems calls are announced on ch 4

units that are available 'on the air' switch at least 1 of their
radios to their 'home channel' - 'home channels' are - ch 4 for metro
ems units - ch 7 for metro fire units - ch 8 for all valley units

for building fire calls or major calls - 3 beeps and the call is
verbaliized once or twice - the comm plan / assigned channels is/are
announced also - on ch 7, or ch 8, or maybe both, or maybe on ch 4
also

units stay on their 'home channel' - except that -

ch 7 units switch to ch 4 when going to metro ems calls

ch 7 units might (not sure) switch to ch 8 when going to valley calls

ch 8 units might (not sure) switch to ch 7 or ch 4 when going to metro calls

for building fire calls - the assigned units switch to ch 9 - when
they arrive at scene, they switch to the assigned tac channel

for river rescues or wildfires - units switch to ch 5 - when they
arrive, they switch to a tac channel - (note - you wont expect to have
river rescues and wildfires on the same day - due to weather)

channels 1, 2, 3, and 13 are used for lower priority unit to unit messages

not sure what the earthquake procedure is - maybe all units switch to
their division channel - 1,2,3,or 13

not sure what ch 10 and 11 are used for - maybe just for the big
chiefs - maybe Battalion Chiefs and higher

anybody who hits their emergency button immediately gets bumped to Ch 6

for mutual threat zone calls - LAFD units may switch to radio channels
of other agencies

no LAFD units have access to any of the highrise security channels afaik

LAFD units might have access to some LAPD radio channels

LAFD BCs might have satellite telephones also

LAFD staff might have official cellphones also

LAFD tablets might have voice comms capabilities also

not sure if LA-RICS or LARTCS channels are available

there might be multiple more channels available on various TRS - but
they might be secondary or backup use only

probably LAFD units have access to Utac and Itac and 700 tac and EMA
and VFire channels and the FIRESCOPE channel load

pretty sure that all LAFD radio are tri-band and can use any channels
at VHF 150 mhz + uhf 450/460 mhz + 700/800 mhz

in addition - there are a couple of air to air channels and 1 air to
ground channel that is 'owned' by LA City

119.975 and 136.025 might also be available for copter to Van Nuys
helibase comms also - maybe the scoopers use those channels also

the county fire chiefs assoc also has a couple of short range channels
that can be used

LAFD ambulances probably all have access to UHF med channels also -
there might be hospital TGs also on some TRS

155.34 might be only used for hospital to hospital data transmissions
(redi-net?)

==========================

dont see this info listed at rrdb nor in the wiki

sometime in the last 5 to 10 years - the fire prevention channel was
repurposed - the ems tac channel was repurposed - the 4th division got
their own 'talk' channel
