Performance check

The front indicator and the internal indicator provide information about the
aspirating smoke detector's current status. The function of the front indicator can
be checked with a test. See 'LED and buzzer test'. [➙ 89]
All the relevant settings can be read with the 'FXS2051 ASD Configuration Tool'
software. The PC communicates with the aspirating smoke detector.
You will find more information in document A6V10332759.

Cleaning

Use a damp cloth to clean the housing. Do not use chemical cleaning agents.

Carrying out water trap maintenance

The condensation water that has been collected must not enter the airflow.
The procedure for draining the water trap varies according to the design. Observe
the following information:
Check the water level regularly. Base the maintenance interval on the usage

conditions to ensure compliance with the mandatory minimum distance
(> 300 mm) between the surface of the water and the airflow.
Condensation water must never be allowed to enter the airflow. Therefore, you

should switch off the aspirating smoke detector before carrying out drainage or
should close the connection between the condensation water and the airflow
while carrying out the procedure.
If an open connection to the pipe system occurs during drainage, the aspirating

smoke detector will interpret the open connection as a fault. In this case, switch
off the aspirating smoke detector while draining the water.
An error message on the aspirating smoke detector can be avoided if the

connection only remains open very briefly (<2 seconds).
