7.3. Inspection Procedure for FAP−OC 500

1. Alternative

D On the central unit, switch the detector zone to be inspected into test mode. This

automatically sets the detector into revision operation and readies it for the detector

test.

. Only in revision operation the detector's individual sensors will trigger with the

corresponding test device. For an alarm, all sensors must trigger at the same time.

The C sensor is triggered using CO test aerosol, the O sensors by being covered

up. No O testing gas is required.

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 Spray the CO testing gas for approximately 1 sec.

. 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 sec.

D Both scattered light areas are covered by the test beaker, so that both optical

sensors are also triggered at the same time.

D The detector triggers the alarm and the red alarm LED flashes.
