Fault indications

All fault repairs should be
carried out by the
servicing organisation.
In a fault condition:
· the common
is lit
· appropriate
is also lit
· internal Fault Buzzer sounds
intermittent tone
· Multiple faults are
simultaneously annunciated
when this does not cause
confusion.
NOTE: Normally the fault lights
will be automatically extinguished
once the fault condition is
rectified.
NOTE: If the system detects a
fire during a fault condition the
fault indicators may be
extinguished.

Cause
A zone fault occurs when a zone circuit cable is open
circuit or short circuit, or the end-of-line capacitor unit
has been disconnected or a detector has been
removed.
A sounder fault occurs when a sounder circuit cable
is open circuit or short circuit, or the end-of-line
resistor unit has been disconnected.
A mains failure occurs when the mains power supply
to the panel is removed. This can occur on mains
fuse failure or mains supply disconnection.
A battery supply failure occurs when the battery
supply to the panel has failed (due to aging process)
or battery voltage is too low or is disconnected or the
battery fuse has failed.
An earth fault occurs when there is an electrical path
for current flow from the system to earth connections.
A Repeat Panel fault occurs when a fault is detected
within the Repeat Panel
A repeat panel link fault occurs when there is a
communication failure between the control and
repeat panels or if the link has been removed or
damaged.
A system fault occurs in the event that the
microprocessor or software fails.
A charger fault occurs when the charger will not
switch off or will not provide charge when on.
A power fault occurs when there is an incorrect 24V
level or fuse failure. Also occurs if the sounder output
supply is at the incorrect level or overloaded during
alarm condition.
