Detector Type Encoding

With the exception of the FAP-425-O-R and FAP-425-O, 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 fire detection, detectors use the time behavior of the fire characteristics, which deviates
significantly from the time behavior of disturbance variables.
FAP-425-DOTC-R and FAP-425-DOTCO-R are 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.

Test instructions for detectors with optical sensor

Since the behavior of the fire chacteristics deviates from the time behavior of a detector check
with aerosol, the detector must be switched to revision mode for a functional test.
Testing in revision mode

–
Notice!
i
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 revision mode
If you want to test detectors in controls, 2-detector or 2-goup dependencies, you must test
them outside the revision mode.

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).
