PARTICULATE LEVEL DISPLAY
The particulate level display, shown in Figure 5, consists of ten amber LEDs that
correspond to the current level of the particulate detected. The LEDs illuminate in
order from Level 1 to Level 10, starting from the bottom of the display and moving
up as the particulate level increases. Each LED represents a ten percent increase in
the particulate level necessary to reach the Alert Alarm Level.

ALARM LEVEL DISPLAY
The Alarm Level Display consists of five red LEDs that correspond to the current alarm
level, shown in Figure 6. These LEDs are located directly above the Particulate Level
LEDs. They illuminate sequentially upward as the severity of the alarm increases.
These alarm levels are configured at default levels when shipped. They may be modi-
fied using the PipeIQ software tool. Each of these alarm levels controls a set of form C
relay contacts. When an alarm level threshold is crossed, the corresponding level LED
illuminates and the relay activates a signal.. These alarm levels and associated relay
outputs can be programmed for either latching or non-latching operation, in addition to
a programmable delay for each level from 0 to 60 seconds. The programmable ranges
for each level are shown in Table 3.

AIR FLOW/FAULT DISPLAY
The FAAST system uses ultrasonic airflow sensing and displays the status in real
time on the User Interface. The air flow/fault display consists of 10-bi-color LEDs
and operates in one of two modes. A fault warning occurs when airflow increases
or decreases by 20% or greater. The green segments indicate how close the current
air flow is to either of these thresholds. During normal operation two adjacent indi-
cators are green and correspond to the current airflow entering the detector. When
airflow is at a balanced level the two green segments are centred on the graph at
levels 5 and 6, see Figure 7. As airflow rises and falls, the green segments move
right and left accordingly. The segment on the far left represents a decrease in air-
flow of 20%. Conversely, movement to the segment on the far right represents an
airflow increase of 20%. A flow fault occurs within 3 minutes of reaching either of
these levels and the minor fault relay is indicated. If the detected airflow is greater
or less than a 50% change from normal, the urgent fault relay is indicated. During
a fault condition, the fault LED as well as the corresponding high or low fault seg-
ment is lit in amber.
Labels
Detector faults are labelled adjacent to the indicators on the Air Flow Fault graph.

USER INTERFACE BUTTONS
The user interface has three buttons, shown in Figure 8, that are used to operate the
unit. Functionality of these buttons are locked out by default from the factory and
require a passcode to enable them (refer to Passcode Access section). The passcode
can be programmed from the PipeIQ software tool.
