Test Instructions for LSN improved version Fire Detectors
The latest generation of FAP-425-DOTC-R Multisensor Detectors is equipped with an
additional sensor for detecting CO in the event of a fire. The CO sensor provides improved
response behavior and increased malfunction suppression in critical environmental conditions.
For fire detection, detectors use the time behavior of the fire characteristics, which deviates
significantly from the time behavior of disturbance variables and also from the time behavior
of a detector check with aerosol.
Therefore, for a functional test, the detector must be switched to revision mode.

The test head must remain over the detector until the detector has been triggered. The
distribution of the test aerosol in the transceiver and thus the trigger time of the sensor can
take up to 10 seconds.
Testing outside the Revision Mode
If you want to test detectors in controls, 2-detector or 2-goup dependencies, you must test
them outside the revision mode. Proceed as follows:

On the fire panel, switch the detector zone to be inspected to revision mode. Thus the
detector is set automatically into revision operation and prepared for the detector test.
Only in walktest mode can the detector's individual sensors be made to trigger one after
the other with the corresponding test device. For this, you should use the service
accessories we recommend.
The optical sensor is tested with the detector tester for smoke detectors with the test
aerosol. The aerosol must be applied for 1 to 2 seconds for the smoke test.
FAP-425-O-R, FAP-425-O and FAP-425-DO-R Trigger the detector with a testing aerosol.
Depending on the sensitivity settings, it can take up to 1 minute till the detector
activates. It is recommended to apply the aerosol in spurts (for example one short spurt
of 1 second, 30 seconds of waiting, another short spurt).
All other detector variants:
