Xtralis VESDA-E VEP Aspirating Smoke Detector
Overview
Xtralis VESDA-E VEP is a mainstream aspirating smoke detector (ASD) engineered to deliver very early warning fire detection across a wide range of high-value and mission-critical environments. Built on Xtralis’ proprietary Flair detection technology, the VESDA-E VEP continuously draws air samples through a network of small-bore pipes into a highly sensitive laser-based detection chamber, identifying combustion particles long before visible smoke or heat would trigger a conventional point detector. Available in one-pipe and four-pipe configurations, the VEP is designed for facility engineers who need dependable, low-nuisance-alarm protection for data centers, cleanrooms, warehouses, archives, and other spaces where early intervention prevents catastrophic loss.
As the official authorized partner and exclusive regional representative for Xtralis, Seven Star LLC proudly supplies the VESDA-E VEP to facility owners, MEP contractors, and fire protection consultants across Oman and the GCC. Every Xtralis VESDA-E VEP unit shipped from our Muscat-based instrumentation division is genuine Xtralis stock, backed by full manufacturer warranty, application engineering support, and locally stocked spares — a level of assurance grey-market resellers in the region simply cannot match.
Detection Principle of the Xtralis VESDA-E VEP
The VESDA-E VEP relies on active aspiration rather than passive point sampling. An internal aspirator continuously pulls air from the protected space through a network of sampling pipes — up to 130 m of branched pipe on the one-pipe model and up to 560 m on the four-pipe model — and channels it into the Flair detection chamber. There, a short-wavelength laser illuminates the sampled air stream, and light scattered by suspended combustion particles is captured by a CMOS imager combined with multiple photo-diodes. This direct-imaging approach generates substantially more particle data than conventional single-point light-scattering detectors, allowing the Xtralis VESDA-E VEP to characterize particle behavior and distinguish genuine incipient fire signatures from dust, steam, or other nuisance sources.
Because detection happens centrally within a sealed, multi-stage filtered chamber rather than at dispersed ceiling-mounted heads, the VEP achieves absolute calibration that remains stable over its operating lifetime, with no drift compensation required. The practical result is a detector with four independently configurable alarm levels — Alert, Action, Fire 1, and Fire 2 — and a sensitivity range spanning 0.005% to 20% obscuration per meter, giving engineers the flexibility to tune response thresholds precisely to the risk profile of each protected zone while keeping false-alarm rates low.
Engineering Design of the Xtralis VESDA-E VEP
Physically, the Xtralis VESDA-E VEP is housed in a compact 350 mm x 225 mm x 135 mm enclosure weighing approximately 4.0 kg, sharing the same mounting footprint, pipe entry, conduit, and electrical connector positions as the legacy VESDA VLP — a deliberate design choice that simplifies retrofit upgrades on existing aspirating systems. The four-pipe Xtralis VESDA-E VEP-A10-P variant adds a 3.5-inch icon-based LCD display for on-unit status review, while LED-only variants (VEP-A00-1P, VEP-A00-P) suit installations where remote monitoring software handles day-to-day status checks.
On the Xtralis VESDA-E VEP, field wiring and commissioning are handled through four 26 mm cable entries, seven programmable relay outputs rated 2 A at 30 VDC, and two programmable general-purpose inputs. The detector communicates over VESDAnet for redundant, bi-directional network reporting, and adds Ethernet and WiFi connectivity as standard so technicians can configure, commission, and monitor the unit remotely using Xtralis VSC and iVESDA software without opening the enclosure. Field-replaceable sub-assemblies — aspirator, smoke detection chamber, sampling module, and filter — mean routine maintenance is completed in minutes rather than requiring full unit replacement.
Key Features
The VESDA-E VEP combines laser-based Flair detection with practical engineering advantages that reduce total cost of ownership over the life of the installation.
- Flair detection technology delivers very early warning with the best-in-class nuisance alarm rejection across a wide range of environmental conditions.
- One-pipe and four-pipe models support pipe networks up to 130 m and 560 m respectively, covering up to 2,000 m² per detector.
- Four independently configurable alarm levels — Alert, Action, Fire 1, Fire 2 — provide graduated response matched to facility risk tolerance.
- Multi-stage filtration with clean air barriers protects the optical chamber and ensures consistent detection performance over the product lifetime.
- AutoConfig and AutoLearn Smoke and Flow automate airflow normalization and alarm threshold learning for rapid, accurate commissioning.
- Ethernet and WiFi connectivity, alongside VESDAnet and USB, enable remote configuration, secondary monitoring, and firmware upgrades.
- An extensive 20,000-event log supports detailed diagnostics, trend analysis, and predictable filter and maintenance scheduling.
- Backward compatibility with VESDA VLP and existing VESDAnet infrastructure simplifies upgrades without re-cabling or re-piping.
Industrial Applications
The VESDA-E VEP is specified wherever early smoke detection protects irreplaceable assets or business continuity. Data centers and telecom facilities rely on the Xtralis VESDA-E VEP to catch overheating cable insulation and electronic component failures before they escalate, while semiconductor fabs and pharmaceutical cleanrooms depend on its low-nuisance-alarm profile to avoid costly unplanned shutdowns triggered by process particulates. Cold storage, warehousing and logistics operations, correctional facilities, hospitals, and heritage buildings across the region also use the VEP where standard point detectors cannot reach or would react too slowly to prevent loss.
As the officially authorized partner for Xtralis, Seven Star LLC distributes and supports the VESDA-E VEP for district cooling plants, hospitality developments, hospital complexes, and industrial facilities throughout the Sultanate of Oman, Muscat, and the wider GCC, including projects in the Sohar and Salalah economic zones. Our instrumentation engineers assist with ASPIRE-based pipe network design, on-site commissioning, and ongoing maintenance contracts, ensuring the detection system performs to specification from day one through years of operation.
