VESDA-E VEP Aspirating Smoke Detector
Summary
The VESDA-E VEP series represents the latest advancement in aspirating smoke detection technology, delivering very early warning with the best nuisance alarm rejection for a wide range of applications. Built on revolutionary Flair detection technology and years of application experience, VEP detectors achieve consistent performance over their lifetime through absolute calibration and provide exceptional user value.
Available in three models – the VEP-A00-1P (single pipe with LEDs), VEP-A00-P (four pipe with LEDs), and VEP-A10-P (four pipe with 3.5″ display) – the series offers flexible solutions for different application requirements. The single pipe model provides coverage up to 1,000 m² (10,760 sq. ft.) while the four pipe models extend protection to 2,000 m² (21,520 sq. ft.).
The revolutionary Flair detection chamber forms the core of the VESDA-E VEP, providing higher stability and increased longevity. Direct imaging of sampled particles using a CMOS imager combined with multiple photodiodes enables better detection performance and significantly fewer nuisance alarms. With Class 1 Division 2 approvals for hazardous locations and comprehensive connectivity options including Ethernet and VESDAnet compatibility, the VEP series delivers enterprise-grade protection with advanced monitoring capabilities.

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 but features a 3.5″ LCD display instead of LEDs for enhanced status visualization and system interaction.
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?
Yes, the VESDA-E VEP series is suitable for Class 1 Division 2 applications covering Groups A, B, C & D, making it appropriate for various hazardous location installations where flammable gases, vapors, or liquids may be present under normal operating conditions.
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.
