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 central unit are retained and will be executed.
D Figure 22. shows the position of the reed switch (Pos. R) in the case of OC
detectors.
. If you imagine the CO sensor (Pos. CO) to be in a 12 o'clock position, the reed
switch (Pos. R) is located at approximately 2 o'clock.
22.
D Bring the magnet close to the reed switch.
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 mode for 60 sec with automatically set test pa-
rameters (e.g. reduction of the delay time to 15 sec). The green LED flashes for as
long as the detector remains in test mode.
D Now hold the test device under the detector so that the test beaker is flush with the
trim ring and seals 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.
D Proceed as in the case of the first alternative:
− spray with CO gas
− leave the test device on the detector for approx. 20 sec, until the alarm is triggered.
. In the case of programmed intermediate alarm storage, longer trigger times occur.
D 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).
D The detector triggers the alarm and the red alarm LED flashes.
