VESDA-E VEU Aspirating Smoke Detector

Search

Key Features

  • Short wavelength laser based detection
  • Advanced detection technology equivalent to hundreds of thousands of sensors
  • Clean air barrier for optics protection
  • Most robust contamination resistance
  • Backward compatible with VESDA VLP

Overview

The VEU series of aspirating smoke detectors are the premium detector of the VESDA-E range. An Ultra-wide sensitivity range; 15 times greater than VESDA VLP, and provision for more sampling holes provide an increased coverage in high airflow applications by up to 40%. Considerably longer linear pipe runs and extended branched pipe network configurations cater perfectly to applications with higher ceilings providing an increased coverage by up to 80% whilst allowing convenient detector mounting for ease of service and maintenance. A range of revolutionary new features provide unsurpassed detection performance, flexibility, field programmability, connectivity and reduced total cost of ownership.

Installation, Commissioning and Operation

VEU features a robust IP40-rated enclosure and is equipped with a powerful aspirator that provides a total pipe length of 800m (2,624ft). It is fully supported by the ASPIRE-E and Xtralis VSC software applications which facilitate ease of pipe network design, system commissioning and maintenance together with compatibility with existing VESDA installations.

Colour Touch Screen Display

The VEU-A10 detector features a 3.5” colour touch screen display which provides a range of status information including smoke level as well as trouble conditions. A simple navigation system allows the user to view all the status information.

VESDAnet™

VESDA devices communicate on VESDAnet which provides a robust bi-directional communication network allowing continued redundant operation even during single point wiring failures. VESDAnet enables primary reporting, centralized configuration, control, maintenance and monitoring.

Ethernet and Wi-Fi Connectivity

VESDA-E detectors offer Ethernet and Wi-Fi connectivity as standard features. The detector can be added to a corporate network, allowing Wi-Fi enabled tablet devices and laptops installed with Xtralis configuration software to connect wirelessly to the detector via the network.

Backward Compatibility

VESDA-E detectors occupy the same mounting footprint, pipe, conduit and electrical connector positioning as VESDA VLP and VLS detectors hence providing complete backwards compatibility.

How it Works

Air is continually drawn from the protected area through the air sampling pipe network and into the detector by a high efficiency aspirator. The air sampling pipe network can contain up to four pipes. The air from each sampling pipe passes through an airflow sensor and then a sample of the air is drawn into the smoke detection chamber via the sampling module, after first passing through the filter. An additional filter provides clean air to protect the optical surfaces inside the detection chamber from contamination.

The Flair™ detection chamber uses the equivalent of 330,000 sensors and sophisticated algorithms for detection and particle classification.

If the detected smoke is higher than the set alarm thresholds it is reported as an Alert, Action, Fire 1 or Fire 2 alarm condition.

Air is exhausted from the detector and may be vented back into the protected area.

Alarms can be signalled via Relays and VESDAnet. Ethernet and Wi-Fi can be used for configuration and secondary monitoring, and a USB interface is provided for initial setup.

A series of LEDs display Alarm, Trouble, Disable and detector power on status. A button allows the user to Reset or Disable the detector. In addition, an optional 3.5” LCD displays detector status including smoke level and a smoke level bar graph, alarm thresholds, trouble status, % airflow level, normalization status and filter life used.
