1.11 Preliminary Systems Check
A preliminary systems check is required after installing the LaserCOMPACT detector, before it is
commissioned for use. The check can be conducted by connecting the detector to a LCD
Programmer or using VSC, or VSM4 PC based software. The preliminary systems check
includes:
• Conducting a VESDAnet communications check
• Accepting factory default configurations, or changing to site requirements
• Normalizing the air flow
• Conducting a basic pass/fail smoke test
For details on 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.
1.12 Maintaining and Servicing the Detector
To maintain the LaserCOMPACT detector at its peak performance the maintenance schedule
given below should be followed. Maintenance can be conducted by the original installer, a
VESDA distributor, or a service contractor. To work effectively the LaserCOMPACT detector
needs to be supported by a well designed pipe network. The VESDA Maintenance Manual
contains a schedule for pipe network maintenance.More frequent maintenance may be
necessary for harsh environments or be required by your local fire authority.
