FAQ
What is the difference between the VEP-A00-1P, VEP-A00-P, and VEP-A10-P models?
The VEP-A00-1P is a single pipe model with LED indicators covering up to 1,000 m², while the VEP-A00-P is a four pipe model with LEDs covering up to 2,000 m². The VEP-A10-P is also a four pipe model covering 2,000 m² and has a 3.5-inch display. The area figures are datasheet maxima and depend on the sampling pipe design.
What is Flair detection technology and how does it improve performance?
Flair is the revolutionary detection chamber that forms the core of the VESDA-E VEP, providing higher stability and increased longevity. It uses direct imaging of sampled particles with a CMOS imager combined with multiple photodiodes, enabling better detection performance and significantly fewer nuisance alarms compared to traditional light scattering methods.
Is the VESDA-E VEP suitable for hazardous locations?
Xtralis lists Class I, Division 2 applications and states that approvals vary by model and region. Confirm the approval for the exact detector and installation with Xtralis before specifying it.
How does the VEP series handle connectivity and networking?
The VEP series offers multiple connectivity options including VESDAnet for robust bi-directional communication with up to 200 devices, Ethernet connectivity for corporate networks, and USB ports for direct PC connection and firmware upgrades. The system is backward compatible with existing VESDA installations and VESDAnet networks.
What pipe network lengths can the VEP series support?
The single pipe VEP-A00-1P supports up to 100m linear or 130m branched pipe networks, while the four pipe models (VEP-A00-P and VEP-A10-P) support up to 280m linear or 560m branched pipe networks. The actual length depends on the number of pipes in use, with configurations from 70m to 110m per pipe depending on the setup.
What maintenance features does the VEP series include?
The VEP series includes extensive maintenance features such as field replaceable sub-assemblies for faster service, smart on-board filter monitoring that retains dust count and remaining filter life, extensive event logging up to 20,000 events, and AutoLearn functionality for automatic threshold setting. The system also supports remote diagnostics and monitoring through various connectivity options.
