Installing a VESDAnet Interface Card into a VLF detector and connecting to a VESDAnet offers many benefits, including:
Central, convenient communications with Xtralis VESDA detectors
VESDAnet allows sophisticated configuration, monitoring and control from local or remote sites. So rather than a technician having to connect to each Xtralis VESDA smoke detector inpidually (sometimes installed high above floor level), they can communicate with all detectors on the network from a central, convenient, location using a laptop.
VESDAnet also allows a system management package (such as Xtralis VSM4) to monitor and report on the status of all devices connected on VESDAnet, facilitating central supervision, management and control of all Xtralis VESDA detectors.
Remote displays and relays for the VLF detector
By installing a VN Card in a VLF detector, remote displays and remote relays can be added to the VLF. This extends the capability and flexibility of the VLF detector.
Features
• Provides seamless VESDAnet fault-tolerant communication
• Quick and simple to install
• Minimal configuration required before operation
• Diagnostic LEDs give visual indication of the card’s status
• Fully transferrable between VLF detectors
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 false 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.
