A restart has occurred in Control Unit no. nn. SSD and S/W download
will automatically be followed by a restart. Also, you can manually do
a restart, see chapter "Restart", page 107. Regarding the restart
codes 00, 03, 13, 25, 14, 25, 50 & 53.
The following restart codes are due to some external disturbance
and are not normal, i.e. call for service technician:
xx=01:
Watchdog Reset.
xx=02:
Accidental jump to reset vector.
xx=04-12:
Unexpected interrupt.
xx=13:
Software monitoring fault.
yy...y = memory address (before restart). Write down the
address and inform the service technician.
FAULT: Sensor zone: xxx address: xx, technical number xxxxxx
The analogue smoke, heat or multi detector is faulty. The detector's
built-in self-verification function has reported a fault. The detector has
to be replaced.
FAULT: Short circuit tech addr nnn <-> nnn, [sub-loop x], loop x,
Control Unit xx
Tech addr nnn <-> nnn describes between which Short Circuit
Isolators the short-circuit is located.
nnn = Technical address for short circuit isolator.
A & B are the built-in isolator in the FT1020G3 FDCIE A-direction and
B-direction respectively.
Note: Each 10th minute a check is performed, if all short-circuits are
corrected (repaired), the communication automatically returns to
communicate in one direction only. The fault has to be acknowledged,
i.e. and it can last up to 10minutes after the acknowledgement before
the communication returns to communicate in one direction only.
Note: This fault might be incorrectly shown if the SA-SB cables are
mixed. If no short circuit can be found, run "check loop" from EBLWin
to get correct information.
FAULT: Site specific data (SSD), Control Unit xx
The Site Specific Data (SSD) in Control Unit no. xx is not downloaded
correctly (a checksum fault, etc.). A new SSD download (via EBLWin)
is required.
FAULT: Site specific data, alert annunciation unit xx, CU xx
FAULT: Site specific data, external presentation unit xx, CU xx
Alert Annunciation Unit
External Presentation Unit
There is no SSD (Site Specific Data) downloaded to the unit or
something is wrong in the downloaded SSD.
FAULT: Supervised input x, technical number xxxxxx
A fault on the supervised input x on 4461 / 4462 / 4464 or 1200 series.
Check the cables / connections (cut-off or short-circuit).
