Maintenance and service
9.1
General
Warning
Maintenance and service work on fire alarm systems are subject in part to country-specific laws and directives.
Maintenance and service work may be performed only by persons trained and authorised by the manufacturer of
the ASD 532.
Depending on application, the ASD 532 must be serviced at least once a year by the manufacturer or by qualified
personnel authorised and trained to do so by the manufacturer. If required (e.g. significant dirt hazard), the ser-
vice interval is reduced to guarantee functional reliability. If filter boxes and/or filter units are used, the service life
of the filter inserts play a role in the service interval. Depending on the level of dust and dirty in the object, filter
service may vary greatly. The optimum filter service life is to be determined on site on a case by case basis.
The operator is obligated to conclude a service agreement with the manufacturer or with an installer authorised by the manu-
facturer if the operator does not have the required service personnel trained by the manufacturer.
The statutory national directives (DIN VDE 0833-1, Cantonal Fire Insurance Union) governing maintenance must be observed.
Servicing, maintenance or inspection work on the ASD 532 may be necessary after an event (fire, fault).
If a detector housing has to be replaced due to a defect, the new ASD 532 is to undergo the same procedure as a first-time
commissioning (initial reset required). All the customer-specific configurations have to be carried out once again on the re-
placed ASD 532.
For maintenance work and function checks, observe the relevant information set out in Sec. 9.3 below.
9.2
Cleaning
Clean the detector housing with a
non-aggressive
cleaning agent (e.g. soap suds or similar).
Normally only the sampling holes need to be cleaned on the sampling pipe tube network. In applications where dirt is a major
issue, it may be necessary to clean inside the sampling pipe (blow out with compressed air or nitrogen). Only
non-aggressive
cleaning agents may be used when cleaning the sampling pipe (e.g. soap and water or similar).
Warning
Aggressive cleaning agents (such as solvents, pure petrol or other alcohol-based agents) must not be used for
cleaning.
