Vesda Aspirating Smoke Detection Systems

Commercial Security

Metroline Security have a proven track-record in installing and maintaining VESDA very early warning smoke detection systems. VESDA, by Xtralis, provide the earliest possible warning of an impending fire hazard and buys time to investigate an alarm and initiate an appropriate response to prevent injury, property damage or business disruption.

With VESDA having the industry’s widest sensitivity range and multi-level warnings, even minute levels of smoke can be detected before a fire has time to escalate.

Vesda Aspirating Smoke Detection Systems Maintenance

As well as designing and installing Vesda aspirating smoke detection systems, Metroline Security provide cost-effective annual maintenance and servicing packages to ensure that the system is functioning as it should.

Vesda Aspirating Smoke Detection Systems

VESDA aspirating smoke detection systems work by continuously drawing air into a distributed pipe network via a high-efficiency aspirator. The air sample then passes through a dual-stage filter. The first stage removes dust and dirt from the air sample before it enters the laser detection chamber. The second, ultra-fine stage provides an additional clean-air supply to keep the detector’s optical surfaces free from contamination, ensuring stable calibration and long detector life as well as minimizing nuisance alarms.

From the filter, the air sample goes through the calibrated detection chamber where it is exposed to a laser light source. When smoke is present, light is scattered within the detection chamber and is instantly identified by the highly sensitive receiver system. The signal is then processed and presented via a bar-graph display, alarm threshold indicators and/or graphic display. VESDA detectors are able to communicate this information to a fire alarm control panel, a software management system, or a building management system via relays or a High Level Interface (HLI).

Gas Detection - VESDA ECO

Gas Detection for Use with Aspirated Smoke Detection

Xtralis the manufacturer of the market leading VESDA aspirating smoke detection (ASD) technology has developed the industry’s first multi-hole aspirated gas detector.

When used with the VESDA range of ASD products; VESDA ECO provides combine aspirated smoke and gas detection. VESDA ECO provides early warning of toxic, oxygen and flammable gas hazards to protect personnel and property whilst ensuring business continuity.

Typical applications include:

  • Battery charging rooms
  • Boiler plant rooms
  • Commercial kitchens
  • Parking garages
  • Utility / service tunnels
  • Refrigerated stores and plant rooms
  • Water treatment and sewerage plants
  • Power generation plants
  • Metal processing plants
  • and more...

How It Works

VESDA ECO uses existing or new VESDA aspirating pipe network to actively monitor for gas escapes and build-ups. Each ECO gas detector can house up to two gas sensors, and additional detectors can be added easily to the VESDA pipe network to monitor more gases if required. Pre-calibrated sensor cartridges are easily replaced in the field and make converting to different gas sensors or replacing sensors a simple task.

The VESDA ECO detector is configured using Xtralis VSC configuration software and can be remotely monitored using Xtralis VSM4 monitoring software. Both VSC and VSM can be used to download data from the onboard memory card for data analysis and trending of historical data.

Integration with other building systems, including fire alarm control panels, PLCs, HVAC and building management systems, provides real-time situational awareness for intelligent emergency response.

VESDA ECO by Xtralis provides significant installation and routine maintenance cost savings over conventional multi-point gas detection solutions, by reducing the number of detectors required to cover an area and by providing easy access for routine maintenance.
