FAULT: High current [sub-loop x] loop x, Control Unit xx
When starting up the control unit or when the COM-loop is reconnected,
the loop current in normal condition is measured and stored.
Main board 5010:
If the stored value is below 100 mA, this fault will later be generated for
a measured current higher than the stored value plus 20mA. (One
example: 75 mA (stored) + 20mA = 95 mA = fault limit.)
If the stored value is over 100 mA, this fault will later be generated for a
measured current higher than the stored value plus 20%.
(One example: 150 mA (stored) + 20% = 180 mA = fault limit.)
Main board 5012 and a SUB-loop connected to 4585:
This fault will be generated for a measured current higher than the stored
value plus 50mA. (One example: 75 mA (stored) + 50mA = 125 mA =
fault limit.)
Note: This fault is not checked in alarm condition. The reason could be
not "full" short circuit on the COM loop but very close to short circuit, e.g.
due to moisture / corrosion / bad contact. Check connections etc.
FAULT: High current consumption, Control Unit xx
The Control Unit current consumption is > 2.8A (> 6.3A in alarm state),
in this case, the battery charging is turned off and remains off until the
current consumption has decreased to < 2.8A (<6.3 A) again.
FAULT: Interlocking input AAA-PP
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 AAA / point PP.
FAULT: Internal short circuit COM loop x, Control Unit xx
Short-circuit on the connection (ribbon cable) to or between the
Expansion Boards (458x) in the Control Unit xx (FT1020G3).
FAULT: Cables mixed [sub-loop x], loop x, Control Unit xx
The two wires L (SA) and C (SB) for COM-loop no. x (0-3), in Control
Unit no. xx, have been mixed (alternated). Check / correct the wire
connections.
FAULT: Loop unit, Technical number xxxxxx
The Brooks customized unit is not functioning, i.e. the unit is faulty. The
unit has to be replaced. This is for 1200 series of panel mounted or field
modules.
FAULT: Loop unit zone: xxx address: xx
technical number xxxxxx
The unit is not working properly, i.e. the unit may be faulty.
Replace the unit.
FAULT: Loop unit zone: xxx address: xx and zone: yyy address: yy
technical number xxxxxx
The unit (not a detector) is not working properly, i.e. the unit may be
faulty. Replace the unit.
