2. 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 mode 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 mode.
3. Now hold the test device under the detector so that the test beaker is flush with the trim
ring and seal it tightly.
Make sure that the test beaker does not tilt, which could cause the detector to be lifted
up and consequently become detached from its fastening.
4. Spray the CO testing gas for approximately 1 second.
The test head must remain over the detector until the detector has been triggered.
Distribution of the CO
testing gas in the test head and therefore the sensor trigger time
can take up to 20 seconds.
5. Both scattered light areas are covered by the test beaker, so that both optical sensors are
triggered as the same time as the CO sensor (no O
testing gas is required).
6. The detector triggers the alarm and the red alarm LED flashes.
4.3 Inspection Procedure for FCP‑O 500
The figure 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.

1. 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
seconds 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.
2. 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. By
covering the scattered light areas, both optical sensors are triggered simultaneously.
Thus, no O
testing gas is required.
3. The detector triggers the alarm and the red alarm LED flashes.
4.4 Reading the Contamination Level
In test mode, the contamination level can be read via the number of the red LED flashes.
1.
Activate the reed switch with the magnet of the test tool.
2. The LED of the detector flashes green once a second as soon as the reed switch has been
triggered.
