Vesda VIC-010 Net Interface Card

The VESDAnet Interface Card (VN Card) is a simple interface card for the range of VESDA VLF by Xtralis aspirating smoke detectors. The VN Card provides seamless VESDAnet communication from the detector to other VESDAnet devices, including configuration and monitoring tools.

Connecting VESDA detectors to building management systems or fire panels

Using an appropriate High Level Interface (HLI), the information on VESDAnet can be transmitted to 3rd party monitoring and control systems such as Building Management Systems (BMS) and Fire Alarm Control Panels (FACP). Preventing nuisance alarms due to outside air pollution.

The VLF can be used as a cost effective reference detector for other active detectors on a VESDAnet. Referencing is a technique used to reduce the risk of unwanted alarms caused by external influences to a building, such as air pollution. It works by offsetting the signal from the active detector in the protected area with a reference signal from a detector monitoring the fresh air intake to the area. This results in the active detector measuring changes in smoke levels that are due only to events in the protected area, rather than those external to the area.
