FAULT: Read/write site data (SSW)
SSW = the data that has changed during operation, i.e. week average sensor
values, passwords, calibration values and event logs.
•
If FT128 was powered down i.e. both mains and battery disconnected
without first doing a Safe shut down of control unit via menu H8/S7 (see
page 129), this fault might be generated when the FT128 is powered
again. After fault acknowledge, the SSW will get default values and the
fault will be corrected (serviced). Supervised outputs have to be
calibrated via menu H5/A1.
•
Some external influence has caused a fault in the SSW. This is very
serious. Call for service personnel/engineer.
FAULT: Restart, code xx addr yyyyyyyyyyy
A restart has occurred in FT128 SSD and S/W download will automatically be
followed by a restart. Also, you can manually do a restart. See also Table 15
page 82
Regarding the restart codes 00, 03, 25, see chapter "
xx=00, 03 and 25 are normal. Only acknowledge the "fault".
The following restart codes are due some external disturbance, and are not
normal, i.e. call for service personnel / engineer:
xx=01:
Watchdog Reset.
xx=02:
Accidental jump to reset vector.
xx=04-19: Unexpected interrupt.
xx=20:
S/W monitoring fault
yy...y = memory address (before restart). Write down the address and
inform the service personnel / engineer.
FAULT: Sensor zone: xxx address: xx
FAULT: Sensor zone zz-aa, zz-aa
to
Press
see the technical address.
FAULT: Sensor zone techn. address xxx
zz-aa = Zone address, xxx = COM loop address
The analogue smoke, heat or multi detector is faulty.
Valid for detector types 33xx / 43xx / 44xx. The detector's built-in self-verification
function has reported a fault. The detector has to be replaced.
FAULT: Several faults on COM-loop
Open (cut-offs) / short circuits in more than one segment on the COM loop.
Normally this fault is generated in conjunction with some open / short circuit faults.
In that case, first correct one fault and the next fault will be presented.
FAULT: Short-circuit, internal COM-loop
Short-circuit on the connection (ribbon cable) to or between the expansion boards
(458x) in the FT128.
