FAS-420-TM Aspirating Smoke Detector
The test adapter is glued into the pipe system in the direct vicinity of the aspirating smoke
detector. During normal operation, the test adapter must always be closed. It is only opened
for maintenance and service purposes in order to admit test gas or smoke.
CAUTION!
Once the detection system of the aspirating smoke detector and the alarm transfer have been
tested (see Page 79), the test adapter must be closed again; otherwise there will be an airflow
malfunction!
