VESDA Smoke Detector Maintenance
A VESDA is a brand of aspirating smoke detector designed and manufactured by Xtralis. From a maintenance perspective, an aspirating smoke detector (also known as an ASD) needs to be maintained differently than the common point type smoke detector.
While this article specifically considers the VESDA, there are other brands of aspirating smoke detector available that these general principes apply.
Defect rectification and reporting
Australian Standard AS1851:2005 A2 provides for the first time a framework for defect reporting for fire protection systems and equipment that has not been previously defined.
The criteria for defect rectification and reporting appears in Section 1 - Scope & General, with specific criteria detailed in Clause 1.15.4 - Defect rectification and reporting.
When the Standard was originally written, the definition of both a 'Critical Defect' and 'Non-critical Defect' was omitted from the definitions found in the Standard. Subsequently in Amendment 1 and Amendment 2, the definitions or examples were established.

This article and presentation, will present with definitions and differences, similarities and relationship between a survey and an audit as described in each of the Australian Standards AS1851-2005 and AS4655-2005.
