Communications Ch 11 + add Flashcards
Difference between “Beacon” & Emergency Alert Tone
Beacon is tone from transmitting radio of FF who depressed EAB; Emergency Alert Tone is heard on “receiving radios”
When are Emergency Alert Tones heard?
Immediately when EAB activated & 2nd tone automatically 10 seconds after initial tone (there are exceptions to 2nd tone being heard 10 sec later)
What would prevent 2nd Emergency Alert Tone to be heard?
FF who activated EAB presses PTT button within 10 seconds, there’s radio activity at the instant the radio attempts to send 2nd tone (radio will postpone until no activity on channel), & FF who initiated resets EAB
What has priority: “Beacon” or received audio?
Beacon: will interrupt any incoming audio on radio transmitting the emergency in order to sound at regular intervals until reset
What if a FF accidentally activates EAB?
Must immediately notify IC, cancel emergency & reset EAB by depressing & holding button approx 2 sec or radio on & off

7136-102 is Lad 136 RRV HT 2
Which Channel on HT is used for Interoperability w/NYPD & can 10-codes be used on this Ch?
Will all radios on Ch 13 hear the emergency alert tone?
Channel 13; Use plain English & refrain from using 10-codes
EAT is audible only on FDNY HT

The EMS/Fire Interoperability (IO) frequency is _
No- all units remain on Primary Tactical Channel, unless specifically instructed to switch to another channel
