Operating Instructions Fire alarm system EBL512 G3, V1.1.x
Network 1: In a redundant network is Network 1normally in a
supervised quiescent state until there is a fault (cut-off or short circuit)
on Network 0.
Check the TLON network cables / connections. (Also for
mixed Network 0 and Network 1 cables.)
Faulty TLON connection board 1590.
The control unit has no power.
Can be shown in conjunction with new S/W download.
FAULT: Control unit xx has wrong
information
Can be shown in conjunction with new software download and/or
when commissioning a system. This fault can be generated due to a
bad TLON network, i.e. communication problems.
One or more control units might have data stored that is not the same
in all control units. If a control unit restarts in conjunction with this
fault, a synchronization will start automatically, otherwise a
synchronization has to be started via menu H8/S8 (or via WinG3).
NOTE! It is important that all control units that are supposed to exist
(SSD downloaded via WinG3) are running and are connected to the
TLON network. The TLON network programming has to be done.
It will take 90-120 seconds until this fault is corrected.
FAULT: Control unit xx high current
consumption
The control unit current consumption is > 3.3A (> 6.3A in alarm state)
and because of this, the battery charging is turned off and will be so
until the current consumption has decreased to < 3.3A (< 6.3 A) again.
FAULT: Cut-off loop x, control unit xx
SCI n <-> SCI n
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 (i.e. < 12 V DC).
SCI n <->SCI n
Isolators (4313) the cut-off is located.
n = A, B, 0, 1, 2, 3, 4, 5, 6 or 7. A & B is the built-in isolator in the
EBL512 G3 A-direction and B-direction respectively, i.e. if no SCI is
used the information will always be:
If only one SCI is used (i.e. 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
56
describes between which Short Circuit
SCI A <-> SCI B
SCI 0 <-> SCI B
or
