VESDA Remote Display - Features

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.

Numeric Display

A 2 digit numerical readout has a number of modes that are indicated by up to four LEDs:

• The current smoke level in % obscuration/m (% obscuration/ft)
• Fire 1 threshold in % obscuration/m (% obscuration/ft). This is the sensitivity of the detector.
• The VESDA zone number
• First Alarm Sector on the LaserSCANNER display - the numeric readout shows the sector (pipe) number that has detected smoke.

Push Button Keys

Four large tactile push button keys enable users to reset, isolate or silence the detector and control the mode of the display module. The buttons can be disabled to prevent operation of it's functions.

A lamp test routine is initiated by pressing the Mode key for two seconds. A Manual Scan can be initiated on the LaserSCANNER by holding the Silence button for 2 seconds.
