3.5.11 Behavior in degraded mode

Building Technologies
Fire Safety
For testing purposes the point detectors can be set to test mode. In test mode the
point detectors react faster and with a higher sensitivity level.
Electronic testing:
The point detectors can be tested with the detector exchanger and tester
FDUD292 or the intelligent detector tester FDUD293.
You will find more information in documents 007227 and 009718.
Physical testing:
● The optical function part on the neural fire detector can also be tested with the
test gas REF8 or REF8-S.
● Test the heat sensors of the neural fire detector with:
– Hot air fan
– RE7T Solo461 heat detector tester kit

Applicable for the FDnet:
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.
Degraded mode operation behavior on control panels that support degraded mode
operation:
● Alarming is still ensured in degraded mode operation.
● In degraded mode 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. The information in the 'List of compatibility' and in the corresponding
control panel documentation must be taken into account during project planning.
