Fire Safety
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.
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.
The status is displayed directly on the radio gateway by means of LEDs.
External indicator, red and green (H1)
Six indicators in the housing (H2, H3, H4, H5, H6, H7). You can see these if
you open the housing cover.
