Applicable for the 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.
The interbases DBS721, DBS728, and DBS729 are also activated and deactivated
in case of a fire alarm in degraded mode operation.
Degraded mode operation on the 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 interbases DBS721, DBS728, and DBS729 have a yellow LED to indicate
when servicing is required.
