Renovation mode should be selected when work that generates a lot of dust or
aerosols is being performed in the room.
In renovation mode, the neural fire detector and the heat detector only trigger alarm
when the temperature exceeds 80 °C for 20 seconds.
The wide-spectrum smoke detector does not trigger alarms in renovation mode
but continues to work normally.
For testing purposes the detectors can be set to test mode. In test mode the
detectors react faster and with a higher sensitivity level. All detectors can be tested
with the detector exchanger and tester FDUD29x. Optical detectors may also be
tested with the test gas REF 8 or REF 8-S. Heat detectors can be tested with a hot
air fan.

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.
Characteristics of degraded mode operation on control panels supporting degraded
mode operation:
Alarming is still ensured in degraded mode operation. However, in degraded
mode operation, only collective alarming is possible. This means that in the
event of an alarm, it is possible to identify the detector line but not the exact
location of the detector triggering the alarm.
If a sounder base is connected to the output for the external alarm indicator, it
is activated in degraded mode operation if there is a fire alarm (only with
detectors and sounder bases with ES ≥ 30); configuration for a specific control
panel is possible.
When the connection for the external alarm indicator is used for a control
function (e.g. hold-open system), the output assumes the configured fail-safe
position (only with detectors with ES ≥ 30); configuration for a specific control
panel is possible.
Degraded mode operation on the FDnet is not supported in the same way by all
control panels. During planning, observance of the information in document
008331 'List of compatibility' and the respective control panel documentation is
therefore mandatory.
