Detector Type Encoding
With the exception of the FAP-O 420 and FAP-O 420-KKW, all detectors are fitted with a
colored ring around the central individual display to identify the detector type.
This facilitates inspection by service personnel.

Test Instructions for LSN improved version Fire Detectors
The latest generation of FAP‑DOTC420 / FAP‑OTC 420 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.
Test Instructions for All Fire Detectors With Optical Sensor
– 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 Solo
A3-001 Test Aerosol.
Notice!
The test head must remain over the detector until the detector has been triggered. The distri-
bution 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:
