Communications Ch 13 & 14 Flashcards
What are the simplex HT channels
1, 2, 3, 4, 5, 6, 7, 8, 10, 13, 16
Transmits & receives point-point on same frequency
Comm 13
Duplex Channels
11, 12, 14, 15
Transmits on 1 frequency but receives a signal back on a different frequency- needs duplex UHF repeater system
Comm 13
What is Channel 9 on HT
Digital channel for future use
Comm 13
In order to enhance FD communications- auxiliary radio communication systems (ARCS) are being installed. Can they be programmed to our HT frequencies
Yes- they can be programmed on our frequency or have their own “Proprietary” frequency requiring in-house radios for members
Comm 13
If a building is equipped w/ARCS who shall activate it
1st Ladder Officer will activate ARCS w/1620 key or ON/OFF switch at Fire Command Station
Comm 13
Who monitors the tactical &/or Repeater channel/Relay messages at ICP
1st Ladder Officer will designate a member to staff
Comm 13
If using a UHF radio repeater channel- when is a functional test performed
Prior to leaving the lobby by first Lad Off
Comm 13
If the IC decides to use the repeater system as a Command Channel for a subway/tunnel emergency- what channel shall be designated members switch to
Channel 14 Primary Subway Repeater channel (15 secondary)
Comm 13
Which members shall switch over to the repeater channels on their HT
Only those directed by IC. All others shall stay on
Comm 13
If repeater system set up at subway- does an HT relay still need to be in place
Must have relay with member on Channel 1
Comm 13
Why is it important to FAST truck to be aware of additional communication channels being used
FAST unit needs to obtain an additional HT for each channel in use & have 1 additional member monitor each new channel
Comm 13
What happens if members encounter a dead spot using ARCS
Unit shall return to a location where previous communications were successful. If successful report dead spot to IC & continue w/ARCS. If unsuccessful use HT on Ch 1 to report repeater failure to IC
Comm 13
Can duplex Radio Repeater Systems support multiple transmissions
No multiple transmissions at same time may cancel out all transmissions
Comm 13
What channel is the Building Duplex UHF radio repeater channel
Channel 11 or 12
Comm 13
If Post to Post Radio Communications is viable- should ARCS still be established
Yes- can be used as a backup
