VESDA-E VEA 40 Holes With LCD Display

The VESDA-E VEA series of detectors combine VESDA reliability and early warning smoke detection with pinpoint addressability and a variety of annunciation options that truly surpass traditional spot detectors. They use patented multi-channel microbore air-sampling with an alarm sensitivity range from 0.1% to 20% obscuration/m (0.03% to 6.10% obscuration/ft). As a multichannel addressable system, the VEA detector is able to divide a protected space into sampling locations, enabling the localization of a fire for faster incident response. The detectors are suitable for protection of areas where pinpoint location of fire events is essential, thus providing ideal fire detection solutions for offices, hospitals, schools, prisons, multi-story dwellings, cabinets in data centers and warehouse racks. A wide range of features provide flexibility, field programmability, enhanced connectivity and reduced total cost of ownership.

Installation and Commissioning

The VEA detector features a robust IP40-rated enclosure and is equipped with a powerful pump that provides up to 100 m (328 ft) capillary tube length. It is fully supported by the Xtralis VSC software which facilitates ease of system commissioning and maintenance. During commissioning, the normalization process establishes the flow performance parameters. A local test port can be used to verify that the system is fully operational. Field replaceable filter, detection chamber, pump and valve components result in less down time and ease of maintenance.

Color LCD display

The VEU-L40-A10 detector features a 3.5” colour LCD display which provides a range of status information including alarm and fault conditions as well as smoke levels. Screens for each type of information are available using a simple navigation system.

VESDAnet™

VESDA detectors and 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 WiFi connectivity

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

How It Works

The VEA detector draws a combined air sample from a network of microbore flexible tubing from all sectors in the protected area, then filters and analyzes the sample in a laser detection chamber. When smoke particles are detected and the smoke level reaches set alarm thresholds, the system will raise appropriate alarm conditions. After a Fire 1 alarm is raised, the system will sequentially scan the sampling locations via the rotary valve to identify one or more sampling locations with the fire alarm event.

The VEA uses a linear vacuum pump which provides superior detection times over long tube lengths. The system monitors the airflow within the installation, allowing detection of breakages or blockages of individual sampling tubes, with faults indicated on the display and to monitoring equipment.

Alarms can be signalled via Relays and VESDAnet. Ethernet and WiFi can be used for configuration and secondary monitoring, and a USB interface is provided for field installation and maintenance.

A series of LEDs display Alarm, Trouble, Disable and detector power on status. A button allows the user to Reset or Disable the detector. Additionally, the VEA-L40-A10 features a 3.5” LCD display which shows detector status including smoke level and a smoke level bar graph, alarm thresholds, trouble status, % airflow level, normalization status and filter life used.
