7.4. Inspection Procedure for FAP−O 500
1. Alternative
D On the fire panel, switch the detector zone to be inspected to test mode. This
automatically sets the detector into revision operation and readies it for the detector
test.
D Hold a sufficiently large object (e.g. the detector test device or the detector
exchanger) in both scattered light areas until an alarm is triggered. No O testing gas
is required.
2. Alternative
D The detector can be tested in normal operation if a test device with magnet is used.
Make sure that the alarm cannot be passed on to higher−level systems.
Programmed activations of the fire panel are retained and will be executed.
D Figure 23. shows the position of the reed switch (Pos. R) in O detectors.
. If you imagine a line through the detector LED to be at the 12 o'clock position,
the reed switch (Pos. R) is located at approximately 2 o'clock.
23.
D The LED of the detector flashes green once a second as soon as the reed switch
has been triggered.
. The detector will now remain in test readiness for 60 sec with automatically set test
parameters (e.g. reduction of the delay time to 15 sec). The green LED flashes for
as long as the detector remains in test readiness.
D Now hold the test device under the detector so that the test beaker is flush with the
trim ring. By covering the scattered light areas, both optical sensors are triggered
simultaneously (no O testing gas is required).
D The detector triggers the alarm and the red alarm LED flashes.
. In the case of programmed intermediate alarm storage, longer trigger times occur.
