3.2.5 Behaviour in degraded mode
Applicable for the FDnet:
If the main processor of the fire control panel fails, the control panel enters
degraded mode operation. Depending on the control panel, the fire control panel
may continue to provide the main alarming functions and signaling functions in
degraded mode operation.
Base sounders with a product version ES ≥ 30 which are operated on point
detectors with a product version ES ≥ 30 are also activated and deactivated in
degraded mode operation in the event of a fire alarm.
Degraded mode operation on the FDnet 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.
