Vesda VRT-J00 Remote Compact Display (7 RELAYS)

Display modules provide real-time indication of the status of a VESDA detector. They have a 20-segment vertical bar graph display, a 2 digit numeric display, an audible sounder, clear alarm and fault indicators. They also have 4 push button keys to control the detector and the mode of the display.

The Display Module can be mounted into a detector unit, a remote mounting box or a 19in sub rack. Several displays can be configured to display information from a single detector in multiple locations.

There are various versions of the display module depending on the type of detector and the relay configuration required. The VESDA VLS display has a fourth mode for the Numerical Display which shows the First Alarm Sector (FAS), this being the number of the sector (pipe) that has detected smoke. For the VESDA VLC the Fire 2 LED is omitted.

Smoke Indication

Smoke levels are continuously shown on a bar graph display where each illuminated segment indicates the current level of detected smoke. The top segment of the bar graph indicates the Fire 1 smoke threshold level and each segment below that level represents 1/20 of the Fire 1 smoke threshold level. To the left of the bar graph are the Fire 1, Action and Alert smoke threshold indicators. At a glance these provide a visual representation of the programmable alarm thresholds showing how close the smoke level is to
triggering the next level of alarm.

Status Lights

High intensity flashing LEDs provide a clear indication of the fire condition and are accompanied by an audible warning appropriate to the alarm condition. Similarly, any fault condition is indicated by a series of LEDs and an audible tone providing a comprehensive range of status information. The audible warning is easily silenced by pressing the Silence button at which point any flashing LEDs are illuminated until the cause of the event is identified, rectified and the system reset.
