9. FAULT WARNING CONDITION
The.CR8506-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.
•. activation.of.any.local.output.contacts.(CONTROL.OUTPUTS).that.may.have.been.programmed.(remote.signalling).
•. the.failure.condition.(FAULT).will.be.indicated.in.the.status.label.on.the.Report.FAULT.panel.
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.
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.(point.8.5.3,.page.51)
•. Carry.out.a.MANUAL.RESET.of.the.failure.signal.as.indicated.under.point.8.5.3.1,.page.51.
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.(point.8.4.1,.page.41)
•. 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.8.4.1.2.to.8.4.1.7).
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 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.8.4.1.2.
LOUDSPK. LINE FAULT panel
..If.the.problem.is.due.to.a.variation.in.the.impedance,.the.CR8506-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...
