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.
