25
EAB activation on simplex
will only reach other simplex users in close proximity dispatch or duplex users will not receive a notification
26
radio channels at a glance
27
portable radio accountability
have a unique encoded 6-digit identifier range from 760001 to 762000
28
Dispatch registered radio database (DRRD)
DC will manage all portable radio issues including replacements, missing radios, conflicting data, etc. only DC have replacement radios and the authorization to contact dispatch with portable radio updates or changes
29
Active status
means radio is operational and assigned to a "seat position"
30
Inactive Status
means radio is non-operational and assigned as "spare"
31
Staffing limits
there are now staffing limits on apparatus to coincide with the number of assigned portable radios 5 assigned per engine and 3 per secondary
32
exceptions to staffing limits
2 high rise has 4 10/11 rescue has 4 4 air light, tenders and boat tows have 2
33
testing radio signal procedure
1. call dispatch or another unit 2. identify yourself 3. advise dispatch/other unit that you want to complete a radio check 4. confirm that dispatch/other unit is able to perform the radio check 5. say "radio check 1 2 3 4 5 how do you read?" Response is Clear x loud (5x5)
34
Portable radio in water
submersible to 2 meters for 2 hours
35
extreme temperature RSM cable
will withstand heat exposure of 500 degrees fahrenheit
36
RSM best practices
wear radio mic on shoulder position radio mic 1-2" away from mouth do not cover the radio loud, clear and controlled voice shield RSM from background noise ensure antenna is not covered when transmitting
37
EAB
Emergency activation button will activate the emergency alert tone, the LED light one the RSM which will flash "SOS" in morse code and the top/front LED screens will flash orange
38
EAB on tactical/duplex
all other transmissions taking place on the tactical channel are interrupted an emergency alert tone will be generated and heard by everyone on that channel and dispatch 6-digit identifier will be displayed on all radios and dispatch console the user will have a hot mic (10 secs) - EAB user should press PTT to avoid being interrupted after 10secs, PTT times out after 60secs
39
Cancelling the Emergency call
push and hold the EAB until a single long beep can be heard - to cancel an EAB, the user will no longer be able to turn off the radio to reset
40
three types of critical messages
Mayday Emergency traffic Urgent message
41
alert tone steps
1. wait for a break in radio traffic 2. press and hold PTT 3. maintain PTT and press EAB 4. release PTT after length to garner attention (3-6secs) 5. press PTT again and proceed with critical message
42
DVRS
Digital vehicle repeater system self-contained radio base station integrated with Motorola APX 6500 mobile radio control head only function is to bridge or connect tactical channel with the corresponding backup simplex channel
43
emergency service specific telecommunication center
separate telecommunications or dispatch centers that the fire department, EMS or law enforcement agency operates
44
Public safety answering point (PSAP)
central location that takes all emergency calls and routes the call to the fire, EMS or law enforcement dispatcher
45
E-911
system combines telephone and computer equipment to provide the dispatcher with information such as the callers location and phone number, directions to the location and other information about the address
46
alternative alerting systems
radio wired telegraph circuit box telephone fire alarm box radio fire alarm box
47
processing emergency calls - collecting information
the type of emergency location of emergency number and location of people involved name and location of the caller callers callback number
48
Basic information to be broadcast
units assigned type of emergency address or location dispatch time current conditions (wind, road closures, etc.) units substituted into the normal assignmentc
49
clear text
plain english rather than agency specific codes
50
direct communication refers
to the straight-line travel of radio signals between the transmitting radio and the receiving radio
51
fireground channel
when units arrive at the incident, a command channel is assigned to the IC while a second tactical channel is assigned for fireground operations
52
radio limitations
distance physical barriers dead zones interference ambient noise
53
Ways to overcome ambient noise
turn off the apparatus audible warning devices when they are no longer needed move away from equipment follow radio procedures at all times move to location that blocks wind use your body PPE to create a wind barrier
54
sender
person who initiates the message
55
receiver
individual to whom the sender is attempting to communicate
56
message
the content that the sender is trying to communicate
57
feedback to sender
reaction of the receiver and its tone
58
interference
anything that prevents the receiver from fully understanding the message
59
two communication rules
must identify themselves in every transmission receiver should acknowledge the message
60
ABCs of good communication
accurate brief concise
61
speak into radio at a proper distance
1-2 inches
