Description

The VESDA Detector VLC505 is a state-of-the-art air sampling smoke detection device designed to deliver early warning fire detection in environments where rapid response is critical. Featuring advanced laser-based detection technology, this compact yet powerful detector continuously monitors air samples drawn through a network of sampling pipes to identify the presence of smoke at the earliest possible stage.

Ideal for applications such as data centers, server rooms, telecommunications hubs, cleanrooms, and high-value storage areas, the VESDA Detector VLC505 ensures maximum protection with minimal disruption. Its detection sensitivity can be adjusted to meet the exact needs of the environment, from ultra-sensitive detection in clean environments to robust monitoring in industrial settings.

One of the key advantages of the VESDA Detector VLC505 is its reliability. With active air sampling, the detector can detect smoke before it becomes visible to the human eye or activates traditional spot-type detectors. This enables earlier interventions and reduces the risk of fire-related damages or downtime. Its built-in event log, auto-learn function, and alarm threshold configuration contribute to intelligent, adaptable protection.

Installation and maintenance of the VLC505 are straightforward, making it suitable for both new construction and retrofit projects. It supports a wide range of configurations, including stand-alone or integrated systems via VESDAnet. With LED indicators and optional remote displays, users can monitor detector status and receive real-time alerts when smoke thresholds are crossed.

The VESDA Detector VLC505 is compliant with major international fire detection standards, ensuring peace of mind for safety managers and facility operators. It’s equipped with fault diagnostics and remote testing capabilities, allowing users to perform routine checks without interrupting operations.

In conclusion, the VESDA Detector VLC505 offers unmatched performance in early smoke detection, making it a preferred choice for sensitive and mission-critical applications. Its intelligent design, adaptability, and proven reliability make it an essential component of any advanced fire protection strategy, and a natural fit for Oman’s data center, telecommunications, and industrial control facilities where early warning fire detection is a regulatory and operational priority.

VLC-505 vs VLC-500

The VLC-505 adds VESDAnet networking capability to the base LaserCOMPACT platform, letting multiple detectors share a common network for centralized monitoring, cross-referencing between detectors, and connection of optional remote display or annunciator modules — a capability the simpler VLC-500 (relay-only) model does not provide. This makes the VLC-505 the appropriate choice wherever a facility needs several detectors reporting to a common fire panel or building management system rather than operating as isolated stand-alone units.

Industrial and Critical-Facility Applications

The VLC-505 is specified for spaces where a spot-type smoke detector would respond too late or is impractical to install directly — server rooms and data halls, telecommunications equipment rooms, control rooms, electrical switchgear rooms, and cleanroom or high-value storage areas common to industrial and commercial facilities across Oman. Because it draws air continuously through a sampling pipe network rather than waiting for smoke to reach a ceiling-mounted spot detector, it can detect an incipient fire condition — such as early overheating in an electrical cabinet or IT equipment — well before visible smoke or open flame develops, giving facility operators time to intervene before an automatic suppression system or evacuation is triggered.

Seven Star LLC supports data centers, telecom operators, and industrial control rooms across Muscat, Sohar, and the wider GCC with genuine VESDA aspirating detection hardware, from initial pipe network design through detector commissioning and VESDAnet integration with existing fire alarm control panels.

Design and Commissioning Notes

Pipe network design for the VLC-505 must respect the manufacturer’s maximum coverage area and hole-spacing rules to guarantee the specified transport time and sensitivity at the far end of each sampling pipe run, so a facility’s ceiling height, HVAC air-change rate, and the value of the protected contents should all factor into how conservatively the alarm thresholds are set. Because the unit supports three independently programmable alarm levels, a common configuration uses the Alert level for early staff notification, Pre-Alarm to trigger a more urgent response, and Fire to initiate the facility’s automatic suppression or shutdown sequence, spacing the response steps so operators have time to investigate before the most disruptive action is taken.

Ordering Information

Seven Star LLC can also supply the complementary pipe network components, sampling points, and the optional remote LED display module used alongside the VLC-505 in a complete VESDAnet installation.

Confirm whether your project specifies the networked VLC-505 or the simpler relay-only VLC-500, since the two share a common housing but differ in networking capability, and provide protected floor area, ceiling height, and any regional fire code requirements so the correct pipe network and detector quantity can be specified before ordering.

VSP-964-03 smoke detection chamber (MK3) for VESDA-E

System accessories listed include the VPS-215-E power supply and the VRT-J00 remote display and relay unit.

Where VESDA aspirating detection is used

Aspirating detection is chosen where point detectors respond too late or cannot be reached for testing: data halls and telecom rooms, switchgear and control rooms, clean rooms, cold stores, warehouses with high racking, cable tunnels and heritage buildings. The VLI extends this to dirty areas such as conveyors and process buildings. Such sites are common in the GCC, where data centers and utility substations are expanding.

Ordering VESDA parts: what we need

Send the detector model and part number from the detector label, for example VLC-505 or the VEP variant code, with the serial number. VESDA-E detectors are made in several variants by pipe count and display type, so the complete code is needed. For filters and chambers, give the VSP number and the detector it serves. For a new detector, the pipe network design has to exist first: tell us the model selected by your designer and the fire panel interface required. We check each number against Xtralis documentation.

Frequently Asked Questions

What detection technology does the VESDA VLC-505 use?

It uses a laser-based aspirating smoke detection principle: air is continuously drawn through a sampling pipe network into the unit's laser chamber, where light scatter from smoke particles is measured before particles become visible to the naked eye.

What is the sensitivity range of the VLC-505?

The VLC-505 detects smoke obscuration from 0.5% to 15% obs/m, covering everything from very early pre-alarm warning to conventional fire-alarm-level sensitivity in one unit.

How many alarm thresholds does it provide and how are they configured?

It provides three independently configurable alarm levels - Alert, Pre-Alarm, and Fire - each adjustable within its own obscuration range, allowing the response strategy to be tuned to the protected space.

How many sampling pipe inlets does the VLC-505 support?

The VLC-505 is a single-pipe-inlet aspirating detector, designed for compact single-room or small-area protection rather than the multi-pipe branched networks used by larger VESDA models.

What air filtration does the unit use to protect its optics?

It uses a dual-stage dust filter - a first stage that removes coarse dust and dirt from the sampled air and a second ultra-fine stage that protects the laser detection chamber - which helps maintain long-term measurement stability in dusty industrial environments.
