The unit contains a 20-segment vertical bar graph display, a 2 digit numeric display, an audible sounder, clear
alarm and fault indicators, and can be mounted in a remote mounting box or 19 inch subrack.
l
Smoke levels are continuously shown on the bar graph display where each illuminated segment indicates
the current level of detected smoke.
l
The top segment of the bar graph indicates the Fire1 smoke threshold level and each segment below that
level represents 1/20 of the Fire1 smoke threshold level.
l
The Alert, Action and Fire1 smoke threshold indicators provide a visual representation of the
programmable alarm thresholds, showing how close the smoke level is to triggering the next level of
alarm.
l
Fault conditions are indicated by a series of LEDs and an audible tone.
l
The numerical readout can show either the current smoke level in % obscuration/m (% obscuration/ft) or
the Fire1 threshold in % obscuration/m (% obscuration/ft).
l
Four buttons enable users to reset, isolate or silence the detector and control the mode of the remote
display module. These buttons can be locked out.
2.8.2
LCD Programmer
The VESDA LCD Programmer is used for configuring, commissioning and maintenance of the devices on
VESDAnet. It is connected via VESDAnet and can be mounted at a remote location.
