MODES OF OPERATION

INITIALISATION

When the FAAST system is first installed it is not configured and gives a fault indi-
cation by illuminating the configuration fault LED indicator. This indicates that the
device has not had its initial configuration loaded and remains in this state until it
is initially configured (refer to the Configuration section below for further instruc-
tions). Once configuration has started, the device performs an automatic initialisa-
tion. This initialisation sets the air flow baseline, the filter clogged baseline and the
particulate level baseline. It is important that the system is connected properly and
the filter is installed correctly when the device is initialized. These initial readings
are used as a reference baseline to indicate when a fault occurs. Initialisation may
take up to five minutes to complete.

STARTUP

Once powered, the FAAST system scrolls the particulate display in green for one
second and then initialises using its stored configuration. The device checks and
establishes its initial airflow, filter and fan settings. If all measurements are normal
it begins normal operation. If any fault is detected the appropriate fault LED will
illuminate.

CONFIGURATION

The FAAST system is configured using the software included in PipelQ. Data is sent
via the built-in Ethernet connection. The device receives the configuration and per-
forms a validation before the configuration becomes active. After validation of the
data, the device performs an initialisation with the new configuration.

Failure of Configuration Validation

If configuration validation fails, the software configuration tool indicates a failure
and the FAAST system illuminates the amber CONFIGURATION fault LED on the
user interface. The device will not accept any of the data as valid. If a configuration
fault occurs during the initial configuration or the device is unable to operate due to
the configuration, a Major fault relay will be set. The device must be re-configured
using PipeIQ. If the configuration fault occurs after the initial configuration has
been accepted, a Minor Fault relay will be set and the device reverts back to its last
valid configuration.
Power or Network Loss during Configuration
During an upload of configuration data, the FAAST system keeps the last known
valid configuration in memory until a complete validation is completed on the new
configuration data. This prevents data corruption in the event of a power loss or
network failure. When power is restored the device performs a Startup with the
last valid configuration. The device also indicates a CONFIGURATION fault on the
user interface and sets the Minor Fault Relay. This occurs only once. When the next
Reset or Power On Reset is performed the device continues to use the last valid
configuration.

NORMAL MODE

In Normal operating mode the FAAST system displays the air flow and current
particulate levels on the user interface. The particulate level is compared to the
threshold levels programmed into the device and activates the appropriate alarm
as particulate levels exceed that threshold. If any fault occurs it activates the cor-
responding fault LED and relay.

TEST MODE

Test mode is initiated through the PipeIQ Live View tab or by depressing the TEST
button on the user interface, when the button is enabled (refer to passcode access
section for activation details). Test mode simulates a fire condition, activating all
ten segments in the Particulate Level display and each segment in the Alarm dis-
play. Each corresponding alarm relay is also activated after any programmed delay
associated with that relay. Activation of the RESET button removes the device from
TEST mode.

RESET MODE

Reset mode is initiated through the PipeIQ Live View tab or by depressing the
RESET button on the user interface, when the button is enabled (refer to passcode
access section for activation details). When RESET is activated all relays are reset.
The device then enters Normal mode operation. If any fault or alarm states remain,
the device re-activates the state automatically.

ACCLIMATE

The FAAST system includes an available Acclimate mode. By allowing the device
to operate in Acclimate mode, a device's susceptibility to nuisance alarms can be
reduced. This provides maximum protection for a device located in changing en-
vironments. The sensitivity of the unit continuously adjusts over time, within the
set limits as the local environment changes. Acclimate mode must be activated and
configured with the software configuration tool which is part of the PipeIQ soft-
ware package. In Acclimate mode the device automatically adjusts the alarm point
between a specified minimum and maximum sensitivity, programmed by the user.
For the first 24 hours of operation the device monitors its environment. After the
initial 24 hour period, the device adjusts the alarm point based on the particulate
levels over a rolling 1 hour period. It then adjusts the alarm level starting from the
insensitive boundary, based on the stability of the environment being monitored.
Setting Acclimate mode
The user chooses the boundaries for each alarm level in the Acclimate mode. The
FAAST system starts from the insensitive boundary and adjusts itself to stay within
the sensitive boundary. It is also possible to have a static alarm level by adjusting
the high and low boundary to the same level. This allows the flexibility to maintain
acclimating levels for some alarms and static levels for others. Table 4 shows the
various levels that are available.
Each Acclimate level is also available for monitoring with the PipeIQ tool. This al-
lows the user to read the current Acclimated alarm level for each alarm.

DAY, NIGHT AND WEEKEND MODE

If Acclimate mode is not desired, the FAAST system can operate in a simple day,
night and weekend mode. This allows the device to have separate threshold levels
for each state. Times can be configured, if desired, for entering and leaving day and
night time operation. The device has an internal time reference (clock) and auto-
matically switches to the weekend mode for Saturday and Sunday.
