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.
