3.3.7 Behavior in degraded mode
Applicable for the FDnet/C-NET:
When the main processor of the fire control panel fails, the control panel works in
degraded mode operation. Depending on the control panel type, the fire control
panel can continue to perform the most important alarming and signaling functions
in degraded mode operation.
Behavior of control panels that support degraded mode operation:
Alarming is still ensured in degraded mode operation. However, in degraded
mode only collective alarming is possible. This means that in the event of an
alarm, it is possible to identify the FDnet/C-NET detector line but not the exact
location of the detector triggering the alarm.
When the outputs are used for controls (e.g. fire controls), the outputs take on the
configured default position in case of a communication failure or current-free
FDnet/C-NET (only devices with ES 30).
Degraded mode operation on the FDnet/C-NET is not supported in the same way
by all control panels. The information in the 'List of compatibility' and in the
corresponding control panel documentation must be taken into account during
project planning.
