4.5.7. Reading Smoke Levels on the VESDA Panels
The Vesda panel only allows the driver to read the average Smoke Level on all the
ports. Polling for individual sector smoke levels will always return a value of zero.
Zone setup
If the zone on the Panel has not been configured the zone must be set to zero in the
FieldServer configuration file.
Sector setup
Setting the sector to zero will allow the driver to poll for the average smoke level.
4.5.8. VESDA Panel start-up delay.
When the HLI is powered on the FieldServer will not be able to communicate with the
Panel for 10 to 30 seconds. During this time the HLI starts up its application code and
initializes various internal parameters.
