Fault
All faults are delayed in order not to generate any unnecessarily faults, e.g. the delay time
for COM loop and zone line input faults the delay time is approx. 45 seconds. Some units
may also have an internal delay time, which makes the delay time even longer, for
example. the Multipurpose I/O unit 3361/4461 has an internal delay time of 30 seconds,
which results in 45+30=75 seconds delay time in total.
In case of a fault condition, the following will happen in FT128:
•
The buzzer in FT128 sounds steady (continuous).
•
The fault relay output for routing equipment (Fault TX) is de-activated (fault relay
is normally activated).
•
Programmable output for general fault is activated and output(s) for general
charger fault may be activated.
•
LED "Fault TX activated" (L11) is illuminating.
•
LED "General fault" (L7) is illuminating.
•
LEDs "Fault / Disablements Alarm devices" (L13), "System fault" (L14) and/or
"Fault / Disablements Fire Brigade TX" (L15) may also illuminate (depending
on the type of fault).
•
A fault message including date, time and status is shown in the FT128 display.
If the fault is generated by an alarm point or zone, the user definable alarm text
will be shown.
For an alarm point / zone also the "alarm text" will be shown.
Example of a fault message:
FAULT: No reply
Date: DD-MM
Press "" to see the technical address:
FAULT: No reply
User definable alarm text for zz-aa
Press "" to see the zone-address:
•
If more than one fault is activated, the text: "More faults" is added after the time.
•
If a fault has been corrected before it has been acknowledged, the "status" text:
"Serviced" is added after the time
•
Fire alarm presentation has higher priority than the fault messages. During fire
alarm presentation, the faults can be shown via the special fire alarm menu X2
see section " Entering Fire Alarm Menu during fire alarm (X1-X9)" page 51.
Faults are normally latched
In this menu (H6), up to 100 faults can be listed:
•
Not serviced / corrected and not acknowledged faults
•
Not serviced / corrected but acknowledged faults (acknowledged)
•
Serviced / corrected but not acknowledged faults (serviced)
If a fault cannot be corrected, it is important to contact service personnel / engineer
immediately.

In EBLWin, Fault can be selected to be either latching (default in AU convention) or non-latching. Latched faults = each fault
must be acknowledged. Non-latching faults = corrected faults will automatically be removed from the fault list (menu H6).

In New Zealand convention, faults must be set to non-latching.
