Communications Procedures Flashcards
(34 cards)
Communications Procedure:
What does UHF and VHF stand for
UHF = Ultra-high frequency
VHF = Very high frequency
Communications Procedure:
When you notice damage or a fault with your Harris XL-200P portable radio, what actions should you take
Report to operational CMDR through chain of command:
Tag radio for repair and report to SO.
SO will ensure radio is tagged with correct repair or fault details.
SO will email Specialised Operations with details and name of CMDR who has arranged collection.
CMDR will arrange tagged radio to be sent to Specialised Operations for repair and spare radio issued temporarily.
Communications Procedure:
Name zones found on ACTF&R radios and detail what can be found at each zone
Zone A: 17 talk-groups - current ACTF&R, includes ACTNSWD304 and A510 NSW FR, simplex channels
Zone B: National simplex channels, hazard reduction burn, southern region RFS units
Zone CT: Common trunk talk-groups, common to all ESA
Zone DZ: Disaster zone
Zone CA: Common analog (ability to talk to RFS on simplex)
Zone CD: Common digital (ability to talk to RFS on simplex)
Zone X: Awaiting to be removed
Communications Procedure:
What TRN talk-group is always monitored by ACTF&R? And on what zone and channel?
OPS 1 Zone A, Channel 1
Communications Procedure:
Describe the difference between simplex and network talk-groups
TRN talk-groups transmit through towers in the ACT and NSW to effectively cover all of the ACT. Often encrypted and monitored by ACTF&R comcen.
Simplex talk-groups communicate direct radio to radio. They operate off the network meaning comcen cannot monitor.
Communications Procedure:
Use pro words to shorten ‘This is pumper 9. I have received your call and I’m awaiting your message.’
Pumper 9. Replying
Communications Procedure:
5 ALIAS names found on portable radios in a standard pumper. Pumper 2
P2 SO (station officer)
P2 MD (motor driver)
P2 SFF (most senior of crew in back seat)
P2 FF (less senior of crew in back seat)
P2 AUX (auxiliary radio)
Communications Procedure:
At what percentage should you change your portable radio battery during daily checks
When below 80%
Communications Procedure:
When changing and charging batteries what are 3 thing you should never do
Remove a battery whilst the radio is turned on.
Place the radio in a charger whilst the radio is turned on.
Use excessive force when fitting a battery to a radio.
Communications Procedure:
When using Zone DZ (OPS1 - 11) what tower will our operations channels default
Black Mt tower.
Communications Procedure:
If you experience continued disruptions on Zone DZ Ops 1-11 during a TRN failure. What could you do?
Change to CH, 18 - 30 which will lock onto different towers. If its still disrupted change to simplex which will communicate radio to radio.
Communications Procedure:
Why does radio shadow occur
UHF radio waves follow a relatively straight line. When hills or large building block these waves they cast a shadow which weakens or totally blocks the signal.
Communications Procedure:
What type of radio used in ACTF&R has the highest output
Base station and mobile radio have higher output at 25W compared to portables at 5W. Its important to remember if reception is poor the mobile may get through when the portable won’t.
Communications Procedure:
What does RSSI mean
Received Signal Strength Indicator
Communications Procedure:
What does the black key mean in the status area of a radio
Connected to an encrypted talk-group, which offer a higher level of security.
Communications Procedure:
Priority colour codes when messaging to comcen
Say Comcen then callsign and colour code.
Wait for go ahead.
Pass message.
Communications Procedure:
List the actions, which routinely communicate the following situation back to comcen. You have recieved a fire call at station?
Receive DTS, crew acknowledge, get in truck and acknowledge on MDT.
Communications Procedure:
List the actions, which routinely communicate the following situation back to comcen. You have arrived at an incident?
Change MDT status to ‘at incident’ followed by a brief R/T.
Communications Procedure:
List the actions, which routinely communicate the following situation back to comcen. You are departing an incident and returning to station?
Brief R/T followed by MDT update to mobile available.
Communications Procedure:
5 pieces of information that could be given in a ‘Sitrep’
Search and Rescue
Change in conditions
Fire extension
Fire is under control
Structural collapse
Communications Procedure:
The pumper is just about to enter the engine bay. The SO has selected the status ‘at home station’ on the MDT. What should he/she ensure before alighting from the vehicle.
Wait for the correct status to show in upper case.
Communications Procedure:
When you PTT on your TRN radio and hear a brief ‘chirp’. What does this mean?
You have received the grant tone and are now clear to talk.
Deny tone is a ‘burp’.
Communications Procedure:
In which vehicles would you find a satellite phone
Both operational CMDR’s vehicles and the RAR vehicle 49.
Communications Procedure:
When would ‘Zone A CH 14 P/Hse Sec3’ be used
Parliament house as its hard to recieve a signal inside. They have given us our own channel to talk between one another.
