EBL512 G3 V. 3.0.X - FIRE ALARM SOLUTIONS OPERATING INSTRUCTIONS
FAULT: High current [sub-loop x] loop x, CU 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 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.)
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 mois-
ture / corrosion / bad contact. Check connections etc.
FAULT: High current consumption, control unit xx
The control unit current consumption is > 2.8 A (> 6.3 A in alarm state) and because of this, the battery charging is turned off and
will be so until the current consumption has decreased to < 2.8 A (< 6.3 A) again.
FAULT: High resistance [sub-loop x] loop x, CU xx
The loop resistance measured by the control unit / 4585 board is too high for the current consumptions. Check cables / connec-
tions etc.
The measured value can be seen in menu H5/A6
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 activa-
tion of the output in the interlocking combination, area AAA / point PP.
FAULT: Internal short circuit, loop x, CU xx
Short-circuit on the connection (ribbon cable) to or between the expansion boards (458x) in the control unit xx (EBL512 G3).
FAULT: Key cabinet, control unit xx
The key cabinet has been opened without a prior fire alarm (i.e. if somebody has opened the key cabinet illegally).
OR
The key cabinet has not been closed within 5 minutes after reset of all fire alarms in the system.
FAULT: Cables mixed [sub-loop x], loop x, CU 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.
