VESDA-E VEU Highest Sensitivity Aspirating Smoke Detector
Summary
The VESDA-E VEU series represents the premium tier of aspirating smoke detectors within the VESDA-E range, delivering unparalleled detection performance for the most demanding applications. With an ultra-wide sensitivity range 15 times greater than VESDA VLP and provision for more sampling holes, the VEU provides increased coverage in high airflow applications by at least 40%, making it the ideal choice for challenging environments requiring maximum protection.
Available in two models – the VEU-A00 with LED indicators and the VEU-A10 featuring a 3.5″ LCD display – both housed in robust IP40-rated aluminum enclosures, the VEU series offers considerably longer linear pipe runs and extended branched pipe network configurations. This advanced capability caters perfectly to applications with higher ceilings, providing increased coverage by up to 80% while allowing convenient detector mounting for ease of service and maintenance.
Built on the revolutionary Flair detection technology, the VEU delivers higher stability and increased longevity through direct imaging of sampled particles using a CMOS imager combined with multiple photodiodes. This advanced detection method enables better detection performance with fewer nuisance alarms. With a maximum coverage area of 6,500 m² (69,965 sq. ft.) and total pipe length capability of 800m (2,625 ft.), the VEU provides unsurpassed detection performance, flexibility, field programmability, connectivity and reduced total cost of ownership for premium fire protection applications.

FAQ
What makes the VESDA-E VEU the premium detector in the VESDA-E range?
The VEU offers an ultra-wide sensitivity range 15 times greater than VESDA VLP, maximum coverage up to 6,500 m² (69,965 sq. ft.), and total pipe length capability of 800m (2,625 ft.). It provides increased coverage in high airflow applications by at least 40% and up to 80% increased coverage for higher ceiling applications, making it ideal for the most demanding fire protection requirements.
What is the difference between VEU-A00 and VEU-A10 models?
Both models offer identical detection performance and coverage capabilities. The VEU-A00 features LED indicators for status display, while the VEU-A10 includes a 3.5″ LCD display providing detailed system information and enhanced user interaction. Both models are housed in robust IP40-rated aluminum enclosures for maximum durability.
What applications benefit most from the VEU’s extended capabilities?
The VEU is ideal for large-scale applications such as high-ceiling warehouses, aircraft hangars, large manufacturing facilities, power generation plants, and any environment requiring maximum coverage with extended pipe runs. Its robust aluminum enclosure and high airflow tolerance make it suitable for challenging industrial environments.
How does the VEU’s pipe network capability compare to other VESDA-E models?
The VEU supports the longest pipe networks in the VESDA-E range with 800m total pipe length capability. Depending on configuration, it supports 160m for single pipe, 150m for two pipes, 130m for three pipes, or 100m for four pipes. This extended reach enables convenient detector mounting and reduces the number of detectors needed for large areas.
What is the sensitivity range advantage of the VEU?
The VEU offers an ultra-wide sensitivity range from 0.001% to 20.0% obs/m (0.0003% to 6.575% obs/ft), which is 15 times greater than the VESDA VLP. This exceptional sensitivity enables detection of the smallest smoke particles while maintaining excellent stability and minimal nuisance alarms through the advanced Flair detection technology.
Is the VEU backward compatible with existing VESDA installations?
Yes, the VESDA-E VEU is fully compatible with existing VESDA installations. It occupies the same mounting footprint, pipe, conduit and electrical connector positioning as VESDA VLP. The VEU is also compatible with existing VESDAnet installations, allowing monitoring of both VESDA-E and legacy detectors via the latest VSC and VSM4 applications.
