Digital Display
The digital display is a back-lit, full graphic unit with a visual display of approx 56 x 27 mm.
The display operates through the software allowing the generation of figures, wording and

The display shows the fume cupboard face velocity in m/sec or fpm when enabled or the
alternative with no velocity reading but showing AIR FAIL / AIR SAFE as continuous display.
All of the above are configurable via the alarm key pad.
An ‘ event time line ’ segmented into 20 x 3 minute segments will scroll across the display
( when enabled) .This takes the form of a graphical ‘ blip’ that will progress from the right hand
side to the left hand side – representing events that have occurred during the past hour.
The alternative to the event time line is a dynamic ‘ bar graph ’ representing the face velocity
The display shows a Horn icon ( with line through it ) when the audible alarm is in the Muted
condition
Sash High – will be displayed when the Sash alarm is enabled and the sash is raised above
the max safe working opening.
This display will alternate on/off with the velocity reading.
Ext Alarm – will be displayed when the external alarm input is activated ( when enabled )
This display will alternate on/off with the velocity reading
Air Fail - will be displayed if the airflow is less than the Low air alarm point.
This display will alternate on/off with the velocity reading
High Air - will be displayed if the airflow is more than the High air alarm point.
