Radio Communications

System Failure and System TroubleSlide2

The Main Points

The back up plan must be easy

Recognize various failures

The plan must be Standard The plan must address ALL departments in Division 112The Incident Commander must adapt on the sceneIt must use existing resourcesSlide3

System Failure

Broken Link

- FD to Dispatch and Dispatch to FD

Broken Link to on scene operationsBroken Link from Incident Commander (I.C.) to resources.Slide4

Types of Failures

Dispatch controller failure (700)

Tower site failure (700)

System Overload/Bonking (700)Complete System Failure (700)Failsoft mode (700)VHF Paging failureSlide5

700 System Failures

Dispatch will notify all departments with VHF capability by the MABAS tone.

Dispatch will call the two Green Bay Battalion Chiefs as well as the stations.

ALL Division departments will have to switch to the SIREN frequency (channel 15)for operations.Necessary radio traffic only.Calls will be paged by VHF using the MABAS tones on BF MAIN.GB will get their calls by phone.Slide6

Types of FailuresSystem Overload

System Overload/Bonking (700)

Too much traffic on a the system

A tone will emit when the PTT button is pressed resulting in the BONKED soundIf this persists then traffic must be moved off the system. SIREN may be used as an optionSlide7

700 System Failures

Failsoft

Activation

In a Motorola trunking system, failsoft refers to a mode of operation when the trunking controller has gone down (Or, the subscriber radio cannot hear any of the control channels), and the system operates in conventional mode, matching channels to specific, pre-programmed frequencies.Failsoft mode still utilizes

the 

repeaters

, but only channels that have frequencies can be used (usually dispatch channels) can be used, and radio emergency buttons stop working

.Slide8

700 System Failures

Failsoft

Activation

All radios will go red/show FAILSOFT Text and beep every 10 secondsBC departments will still be paged on the VHF system assuming it is still functioningGB can get their calls as usualAll communications for BC departments are on one channel there are no talkgroups in FailsoftThis happens automaticallySlide9

700 System Failures

Failsoft

Activation

Options remain available when in FailsoftSIREN may still be the best answerOther Annex K 800 frequencies are in each radioThe IC may develop a radio plan when the incident dictatesSlide10

Working Incidents with 700

mhz

System Failure/Problem

It is the responsibility of the Incident Commander to account for personnel if a radio system failure occurs during an incident.It is up to the individual department to decide how to conduct a PAR and or to notify all operating units on scene of the radio failure. This may include any of the following suggestions- deployment of a secondary team into the IDLH atmosphere to notify personnel, and/or sounding of the air horns on scene.Slide11

“VHF Failure”

B.C. Fire

depts

main dispatching channelNo ability to page callsNo ability to tone MABASDoes not effect GBMFD dispatching700 system will probably still be functional.Dispatch will notify each Fire Chief of failurePossible solution is to staff the stationsSlide12

“POINTS TO REMEMBER”

ALL communications for every department in Division 112 should initially take place over SIREN when a

total

radio system failure occurs. Only Relevant traffic.A working fire or life safety issue will take absolute priority over all other traffic.Slide13

“POINTS TO REMEMBER”

The IC may have to develop a radio plan based on the type of failure and situation encountered.

The IC may have to coordinate this with dispatch by phone

Simple is best but options are available (Annex K freq’s)
