Operating Instructions Fire alarm system EBL512 G3, V2.2.x
mixed Network 0 and Network 1 cables.)
Faulty TLON connection board 1590 / 5090.
The control unit has no power.
Can be shown in conjunction with new S/W download.
FAULT: Cut-off loop x, control unit xx
SCInn <-> SCInn
This fault is indicating a cut-off (break) on COM loop x or the COM
loop voltage is too low at the end of the loop.
SCI n <->SCI n
Isolators the cut-off is located.
n = A, B, 0, 1, 2, 3, 4, 5, 6 .....63. A & B is the built-in isolator in the
EBL512 G3 A-direction and B-direction respectively.
If no SCI is used the information will always be:
SCI B
.
If only one SCI is used (e.g. 4313 no. 0), the information will be:
SCI A <-> SCI 0
...and so on.
If it is a single break (cut-off) on the loop there will be no other fault
messages.
If there are several breaks on the loop the message shows the last
isolator before the break in the A-direction (incl. the following
isolator). There will also be a "FAULT: No reply ....." message for
each unit that EBL512 G3 cannot find and "FAULT: Multiple faults
...".
th
NOTE! Each 10
minute a new attempt is made to communicate in
one direction only.
When all breaks are repaired (corrected) the communication
automatically returns to communicate in one direction only.
FAULT: Detector removed zone xxx address xx
A wireless smoke detector 4611 has been removed from its base..
FAULT: Earth fault (minus),
control unit xx
FAULT: Earth fault (plus),
control unit xx
Earth fault is detected in control unit no. xx. 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).
