FAULT WArNING CONdITION
The.PA8506-V.system.has.a.diagnostic.routine.that.monitors.constantly.availability.of.the.VES.sources.and.the.soundness.of.the.critical.path.of.
the.signals.providing.the.functions.in.emergency.conditions.
9.1
SySTEM OPErATION ANd SIGNALLING IN GENErIC CONdITIONS
9.1.1 System signalling due to an existing "Fault Warning Condition"
If,.with.the.system.in.its.normal."Quiescent.Condition",.the.monitoring.system.detects.a.cause.of.a.failure,.it.promptly.activates.signalling.of.a.
"Fault.Warning.Condition",.as.follows:
•. the.FAULT.LED.(visual.signal).will.light.up.
•. a.BEEP.(acoustic.signal).will.be.heard.via.the.monitoring.loudspeaker.
•. the.local.CONTROL.OUTPUT.contacts.(remote.signalling),.if.programmed,.will.be.activated.
•. the.failure.condition.(FAULT).will.be.indicated.in.the.status.label.on.the.Report.FAULT.panel.
N.B.:.In.a.12-zone.system,.if.the.fault.concerns.items.of.equipment.pertaining.to.the.other.PA8506-V.unit,.the.FAULT.LED.will.flash.
9.1.2 System signalling following cleaning of "Fault Warning Condition" (rES)
If. the. cause. of. the. failure. is. cleared. automatically,. without. any. action. on. the. part. of. the. operator,. the. system. will. return. automatically. to. its.
"Quiescent.Condition",.resetting.all.the.signals.described.above.and.storing.the.last.failure.that.occurred.as.follows:
•. The.word.RES.will.be.shown.on.the.status.label.of.the.Report.FAULT.panel.indicating.that.the.failure.has.been.cleared..(see.point.8.5.1).
9.1.3 resetting the signal following clearing of a failure (FAULT rESET)
To.reset.a.signal.referred.to.a.failure.that.has.been.cleared.and.stored:..
•. From.the.OPERATOR.menu,.go.to.the.FAULT.panel.(see.point.8.6.5)
•. Carry.out.a.MANUAL.RESET.of.the.failure.signal.as.indicated.under.point.8.6.5.1.
Note: In the event of failure of a loudspeaker line due to a short circuit, once the line is repaired it is necessary to carry out a MANUAL RESET of the failure
from the OPERATOR menu, in order to re-activate the audio signal on the output of the line concerned.
9.1.4 recommended procedure during a Fault Warning condition
The.procedure.to.be.followed.during.a.Fault.Warning.condition.is.the.following:
•. From.the.INSPECTION.menu,.go.to.the.FAULT.panel.(see.point.8.5.1)
•. Reset.the.acoustic.signal.manually..(RESET.BEEP.-.see.point.8.5.1.1).
•. Check.the.category.of.the.FAULT.diagnosed.and.go.to.the.appropriate.sub-panel.
•. Check.the.cause.of.the.failure.and,.if.possible,.restore.correct.operation.following.the.instructions.contained.in.the.table.referred.to.the.sub-
panel.(see.points.from.8.5.1.3.to.8.5.1.8).
If.upset.is.successfully.cleared,.termination.of.the.Fault.Warning.condition.will.be.signalled.as.follows:
•. The.FAULT.LED.will.extinguish.
•. The.output.contact.involved,.if.any,.will.be.de-activated.
•. The.word.RES.will.appear.in.the.status.label.of.the.Report.FAULT.panel.to.show.that.the.failure.has.been.cleared.
Upon.completion.of.the.procedure,.it.is.advisable.to.reset.the.signal.for.the.failure.that.has.been.cleared,.as.indicated.under.point.9.1.3.
9.2 SySTEM OPErATION ANd SIGNALLING IN CASE OF FAILUrE OF AN AMPLIFIEr
In.the.event.of.failure.of.one.of.the.two.internal.amplifiers.of.the.PA8506-V.or.of.the.external.amplifier,.if.any,.in.addition.to.signalling.the.failure.
as.indicated.under.point.9.1.1,.the.system.will.switch.operation.of.the.system.to.the.single-channel.mode,.stopping.broadcasting.via.the.Music.
channel..Operation.in.the.single-channel.mode.is.signalled.as.follows:
•. With the system in the "Quiescent condition" .
The.wording."NOT.AVAILABLE".will.appear.on.the.MUSIC.panel.in.the.field.of.the.display.dedicated.to.the.music.vu-meter.and.to.the.BGM.
Source.
•. With the system in the "Voice Alarm Condition" due to an Automatic Emergency: .
The.wording."Only.one.channel.available.–.FAULT.CONDITION".will.appear.on.the.display.for.the.CONTROL.INPUT.STATUS.panel..In.the.event.
of.a.contact.programmed.for.simultaneous.broadcasting.of.two.messages,.the.status.label.of.the.zones.intended.to.receive.the.Alert.message.
that.can.no.longer.be.broadcast.will.indicate..FAIL.(Failure).
•. With the system in the "Voice Alarm Condition" due to a Manual Emergency:
The.wording."Only.one.channel.available.–.FAULT.CONDITION.will.appear.on.the.display.of.the.EMERGENCY.panel..If.the.two.messages.were.
being.broadcast.simultaneously,.the.status.label.of.the.zones.intended.to.receive.the.Alert.message.that.can.no.longer.be.broadcast.will.indicate. .
FAIL.(Failure).
9.3 SySTEM OPErATION ANd SIGNALLING IN THE EVENT OF A SPEAKEr LINE FAILUrE
A.failure.of.the.speaker.line.may.be.due.to.various.different.causes..The.associated.signalling.and.the.activities.required.are.described.under.
point.8.5.1.3.Panel.LOUDSPK. LINE FAULT..If.the.problem.is.due.to.a.variation.in.the.impedance,.the.PA8506-V.will.continue.to.broadcast.the.
audio.signal.output.from.the.zone..If.it.is.due.to.a.short.circuit.on.the.line,.the.system.will.disconnect.the.failed.line.and.broadcast.the.audio.signal.
on.the.other.line.serving.the.same.zone..
•. with system in "Voice Alarm Condition"
Whatever.the.cause.of.the.failure.on.the.speaker.line.may.be,.and.even.if.no.message.has.been.activated.to.be.played.out.to.the.failed.zone,.the.
word.FAIL.will.appear.on.the.CONTROL.INPUT.STATUS.panel.and.on.the.EMERGENCY.panel,.on.the.zone.status.label..The.wording.FAIL.has.
priority.over.the.indication.of.the.current.message.sent.to.the.output.zone..
9.4 rESETTING THE "BEEP" IN SySTEM FAULT CONdITIONS
To.reset.the."beep".signal,.turn.the.+/-..knob.repeatedly.in.a.clockwise.direction.until.the.beep.is.silenced.
