FAULT: Detector removed, techn address xxx
zz-aa = Zone Address. xxx = Com loop address
A wireless smoke detector 4611 has been removed from its base.
FAULT: Earth fault (minus)
FAULT: Earth fault (plus)
Earth fault is detected in FT128. The system voltage is normally 24
V
DC
.
+24 V to earth is normally 12.5 V. 0 V to earth is normally 11.5 V. Voltage to
earth < 3.4 V = Earth fault (minus).
Voltage to earth > 18.3 V = Earth fault (plus).
Check all cables (for damage, etc.). The function of the FT128 cannot be
guaranteed. Call for service personnel/engineer.
FAULT: Earth fault, techn address xxx
Valid for an external power supply 3366 (4466) connected on the COM loop.
Check all cables connected to the unit.
FAULT: EPU x
EPU=1728. (External Presentation Unit)
The unit is programmed as another type to the type configured in the SSD or a
faulty unit.
FAULT: Expansion board x
Valid for Expansion Boards 4580, 4581 and 4583 i.e. no. x, mounted in FT128.
Also valid for the I/O Matrix board 4582 connected on the COM loop.
Internal fault on the board and it may needs to be replaced.
FAULT: External fuses
The fault is to be found in the external power supply equipment (blown fuses,
etc.). A fault output is connected to a programmable input in the FT128 system.
Check the input as well.
FAULT: External power supply
The fault is to be found in the external power supply equipment. A fault output is
connected to a programmable input in the FT128 system. Check the input as well.
FAULT: Extinguishing system
The fault is to be found in the extinguishing system, which has a fault output
connected to a programmable supervised input in the FT128 system, i.e. to an
expansion board 4583. Also check the input connections.
FAULT: Factory settings
The battery charging factory settings have been "changed", e.g. because of some
external disturbance. The main board has to be replaced since the battery
charging function cannot be guaranteed.
