FAULT: Input x exp board x
A fault on the supervised input x on the expansion board (4583) with address x.
Check the cables / connections (open or short circuit).
FAULT: Interlocking input AA/PP
AA/PP = Area – Point
An interlocking input is not activated within the time set for fault activation (5-255
seconds). The time is counted from the activation of the output in the interlocking
combination, area AA / point PP.
FAULT: Loop unit zz - aa
Press "

FAULT: Loop unit techn. address xxx
zz-aa Zone address, xxx = COM loop address
The communication with the unit is not established, i.e. the unit is probably faulty.
FAULT: Low battery capacity
Battery internal resistance > 1.4 Ω will generate a fault.
The "Low capacity voltage diff." value shown in menu H5/A4 is > 700 mV.
The battery might be too old.
•
Check / adjust the power supply voltage (must be 24 V
DC
).
•
Check the charging voltage over the battery respectively (13.5-13.8
depending on the actual charging step).
•
Check the voltage over a disconnected battery (fully charged > 13 V).
The battery should normally be replaced.
NOTE! The battery check is performed every 4th hour, i.e. it can take up to 4
hours until the fault status be "corrected".
In the New Zealand convention
: The battery charging is turned off 60 minutes
every 24
th
hour. A battery voltage < 24.4 V during these 60 minutes will generate
a fault.
If a fault is generated it will automatically be
Serviced
after the 60 minutes.
FAULT: Low voltage
System voltage < 21.6
V
DC
, in the FT128. Check the power supply, output voltage,
which must be 24 V DC. Replace the rectifier if required.
Note
: A FT128 powered by the back-up battery only, will shut down at a battery
voltage of 21.4 V, in order to avoid damaging the batteries. When this fault is
detected, the log is saved to flash automatically, in order to keep the log intact
after a power failure.
FAULT: Low voltage, techn address xxx
System voltage < 21 V DC in the external power supply unit 3366 or 4466.
Check the power supply, charger output voltage must be 24 V
DC
. Replace power
supply if required.
FAULT: Mains
