Xtralis VLC-505 Aspirating Smoke Detector
Overview
The Xtralis VLC-505 is a VESDA LaserCOMPACT aspirating smoke detector purpose-built for very early warning smoke detection in single and smaller protected environments where space is at a premium. Combining VESDA laser detection technology with a modified aspirator design in a compact enclosure, the Xtralis VLC-505 provides absolute smoke detection across coverage of up to 800 m² (8,000 sq ft), with a wide sensitivity range of 0.005 to 20% obscuration per meter that lets a single detector protect archives, production machinery enclosures, ceiling voids, prison cells, wet benches, and critical process tool cabinets.
As the official authorized partner and exclusive regional representative for Xtralis, Seven Star LLC proudly supplies the Xtralis VLC-505 aspirating smoke detector to fire protection contractors, data centers, and industrial facilities across the Sultanate of Oman, Muscat, and the wider GCC region. Facilities in Sohar and Salalah specify the Xtralis VLC-505 when they need a genuine VESDAnet-compatible detector backed by full manufacturer traceability, and Seven Star LLC ensures every unit shipped locally carries authentic documentation, commissioning support, and warranty coverage.
Operating Principle of the Xtralis VLC-505
The Xtralis VLC-505 draws air continuously through a single pipe inlet network using an integral aspirator, pulling samples from the protected space into a laser-based detection chamber. Inside the chamber, VESDA laser detection technology analyzes the sampled air for combustion particles at concentrations far below the threshold visible to conventional point smoke detectors, allowing the Xtralis VLC-505 to identify a developing fire condition at the earliest possible incipient stage — often before visible smoke or measurable heat is present at the protected area.
Clean air barrier optics protection keeps the detection chamber free of contamination during continuous sampling, sustaining measurement accuracy over long service intervals in dusty or industrial environments. The Xtralis VLC-505 continuously monitors air flow through the sampling pipe network and uses its AutoLearn capability to establish a baseline for normal environmental conditions, reducing nuisance alarms while maintaining the sensitivity needed to detect a genuine incipient fire condition across three configurable alarm levels.
Engineering Design of the Xtralis VLC-505
Xtralis designed the VLC-505 around a simplified display and a compact enclosure suited to installation in confined ceiling voids, equipment cabinets, and utility spaces where a full-size aspirating detector will not fit. Five status LEDs give technicians an at-a-glance view of detector condition, alarm state, and fault status without connecting a separate monitoring terminal, while the single pipe inlet design simplifies pipe network layout for smaller protected zones compared to multi-pipe aspirating systems intended for large open areas.
The VLC-505 variant communicates over VESDAnet, Xtralis’ proprietary detector networking protocol, allowing multiple VESDA detectors — including VLC, VLP, and VESDA-E units — to be integrated into a single site-wide very early warning fire detection network with centralized monitoring and configuration. The detector provides three programmable relays for direct interface with fire alarm control panels, along with optional remote display and relay capability for installations where the detector itself is not readily visible or accessible to facility personnel.
Key Features
The Xtralis VLC-505 aspirating smoke detector combines laser-based early warning detection with a compact, space-efficient design. Core capabilities include:
- Absolute smoke detection coverage of up to 800 m² (8,000 sq ft) per detector.
- Wide sensitivity range of 0.005 to 20% obscuration/m for both very early warning and standard alarm thresholds.
- VESDAnet communication for integration into a networked, site-wide detection system.
- Single pipe inlet design simplifying pipe network layout in space-constrained protected areas.
- Five status LEDs providing immediate local visibility of detector and alarm condition.
- Clean air barrier optics protection that sustains detection accuracy in continuous operation.
- Three programmable relays and three alarm levels for direct fire alarm panel interface.
- AutoLearn capability and continuous air flow monitoring to reduce nuisance alarms.
Industrial Applications
Facilities across the region deploy the Xtralis VLC-505 wherever early warning fire detection is required in a compact, cost-effective footprint. Data centers and telecommunications rooms throughout Muscat use the Xtralis VLC-505 to protect server cabinets and cable risers, while correctional facilities specify it for cell and corridor protection where tamper resistance and low-profile installation matter. Industrial plants across Oman deploy the VLC-505 to protect production machinery enclosures, wet benches, and critical process tool cabinets in semiconductor and precision manufacturing environments, and archives, museums, and heritage sites in Sohar and Salalah rely on its very early warning sensitivity to protect irreplaceable assets without the false-alarm risk of conventional point detectors.
As the officially authorized partner for Xtralis, Seven Star LLC distributes the Xtralis VLC-505 to fire protection engineering firms, systems integrators, and facility management teams operating within the Sohar and Salalah economic zones, as well as to industrial clients throughout Muscat and the broader Sultanate of Oman. Because every Xtralis VLC-505 is genuinely sourced through the authorized supply chain, fire safety consultants and building owners can specify it with confidence in its certified performance for life-safety systems across the GCC.
