10 Preliminary Systems Check

A preliminary systems check is required after installing the VESDA VLC-EX detector, before it is
commissioned for use. The check can be conducted by connecting the detector to a LCD Programmer or by
using the Xtralis VSC software. The preliminary systems check includes:

l

Conducting a VESDAnet communications check

l

Accepting factory default configurations, or changing to site requirements

l

Normalizing the air flow

l

Conducting a basic pass/fail smoke test

For details on the preliminary systems check refer to the LCD Programmer or the relevant software manuals.
Refer to the VESDA LCD Programmer and Commissioning Guides for further details.
