MODES OF OPERATION
INITIALIZATION
(Refer to the Configuration section below for further instructions). Once con-
figuration has started, the device performs an automatic initialization. This
initialization sets the air flow baseline, the filter clogged baseline and the par-
ticulate 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. In-
nitialization may take up to five minutes to complete.
STARTUP
Once powered, the FAAST system initializes 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 de-
tected the appropriate fault LED will illuminate.
CONFIGURATION
The FAAST system is configured with FACP. The device receives the configura-
tion and performs a validation before the configuration becomes active. After
validation of the data, the device performs an initialization with the new con-
figuration.
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, the device must be re-configured
by the FACP. 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 of E-mail
During an upload of configuration data, the FAAST system keeps the last
known valid configuration in memory until a complete validation is com-
pleted 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. 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 acti-
vates the corresponding fault LED and relay.
TEST MODE
Test mode is initiated through the FACP or by depressing the TEST button on
the user interface, when the button is enabled (refer to passcode access sec-
tion for activation details).
ACCLIMATE
The FAAST system includes an available Acclimate mode. By allowing the de-
vice 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 environments. 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 FACP. In Acclimate mode the de-
vice automatically adjusts the alarm point between a specified minimum and
maximum sensitivity, programmed by the user. For the first 24 hours of opera-
tion 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.
ISOLATION
Isolation mode is initiated by pressing and releasing the ISOLATE button on
the user interface when the button is enabled (refer to the passcode section)
or placing the device into MODE 6 from the panel. When the ISOLATE button
is activated or the command is issued, the isolation fault indicator illuminates
on the user interface. In this mode the device operates normally but will not
activate relays for any alarm or fault levels . Fire and fault events can still be
seen on the user interface and the web server will send e-mail notification
of events if enabled. Isolation mode will be held through resets and power
outages. The device will remain in isolation mode until the isolation mode is
removed by pressing the ISOLATE button or removing MODE 6 at the panel.
DISABLE
Disable mode is initiated by pressing and holding the ISOLATE button on the
user interface for 3 seconds when the button is enabled (refer to the passcode
section) or issuing a disable command from the panel. When the ISOLATE
button is activated or the
disable
command is issued, the isolation fault indi-
cator illuminates on the user interface. In this mode the fan switches off and
the device does not report any alarm or fault levels on the user interface. This
mode should only be used when the system needs to be taken offline. This
mode will be held through resets and power outages. The device will remain
in disable mode until the disable mode is removed by pressing
and holding
the ISOLATE
button for three seconds
or the disable mode is removed at the
panel.
USER BUTTON ALTERNATE FUNCTIONS
Passcode Access
The user interface has an option that requires users to enter a security code
before the front panel functions become active. All passcodes must be 4 digits
in length using numbers 1 through 9 (zero cannot be used). Passcodes may
only be changed through the device specific page. In addition, the configura-
tion software tool is capable of locking out buttons individually, so that cer-
tain buttons may be accessed without a passcode, if desired.
The default passcode is ‘1111’.
The TEST button enters digits, the MODE button is used to enter the unlock
mode and the ISOLATE button increments the current digit.
