Visual inspection

Check the following:
Assuming the pipe system is freely accessible, check it is securely attached

and free of damage.
The aspirating holes of the pipe system are clear.

The intake pipe and connecting cables are securely connected.

The device retainer (if present) has been correctly secured.

The smoke aspiration system is free of damage. See also 'Fault indication

[➙ 109]'.

Checking the pipe system

In areas that are prone to dust particles or freezing, check whether the aspirating
holes of the pipe system are blocked. Blow out the pipe system and the aspirating
holes (using compressed air, if necessary). To do this, use a portable compressed
air cylinder (blowing-out equipment) or a permanently installed manual blowing-out
system.

Status queries with service devices

If the aspirating smoke detector is connected to the FDnet/C-NET detector line via
communication transponder FDCC221S, line tester FDUL221 can be used.
You will find a detailed description of line tester FDUL221 in document 008250.
The aspirating smoke detector can communicate directly with detector exchanger
and tester FDUD292 or intelligent detector tester FDUD293 via the MC link
interface on the communication transponder.
You will find a detailed description of these test devices in documents 007227 and
009718.
All the relevant settings can be made with the 'FXS2051 ASD Configuration Tool'
software. The PC communicates with the aspirating smoke detector.
