The following table should help you to determine the maximum current:
Device / Module /
Element Current draw
Module Comment
MPC 150 mA + load factor of all connected elements
FDC 70 mA + load factor of all connected elements
GMG 80 mA + load factor of all connected elements
PMG 35 mA + load factor of all connected elements
Load factor element 0.25 mA SIGMALOOP-PMG-GMG Sinteso elements
Table 8: Determining maximum current
A fully expanded FDnet loop with 280 load factors has a current draw of
around 70 mA.
4.4.3 Dual SOC
A second SOC module (central computer) takes over the task of the first SOC module com-
pletely in the event of a failure.
When installing systems under VdS guidelines with:
•
central ÜE activation in SIGMANET
•
SIGMASYS M control and indicating panels in SIGMANET
•
control and indicating panels that control several extinguishing sectors
If several SIGMASYS C control and indicating panels are networked by SIGMANET and if central
ÜE actuation is required, the ÜE must be connected to a SIGMASYS M control and indicating
panel with Dual SOC.
Warning:
With Dual SOC operation, both modules must have at least S24230-A100-A3
release status.
Both modules must have the same firmware status.
4.4.4 SOC P module (since end 2006)
Since March 2007 the SIGMASYS M control and indicating panels and M cores have
been supplied without the SOC module.
The previous SOC module or the SOC P module can be installed as an option. ( P stands for
performance)
The SOC P module has a much faster computer, more memory and faster interfaces than the
SOC module.
Control and indicating panels with the "SIGMANET P " SOC P module are networked using
the FN2001-D1 networking module, which must be ordered separately. In the case of Dual
SOC P operation, both SOC P modules must each be equipped with an FN2001-D1 network-
ing module.
The interfaces of the SOC P module are made available on the APL20 P, which must be or-
dered separately.
With Dual SOC P operation an additional crossover Ethernet cable, order number
A5Q00019146, is required. Only one APL20 P is needed for both SOC P modules.
