SS-600-000 8 I56-3904-001
NUMBER NAME DESCRIPTION
1 Low Flow Fault Device has decreased airflow
2 Configuration Configuration of device with configuration software has failed.
Device was interrupted with a power loss during configuration. A Reset will
clear this fault and device will revert back to it's last good configuration.
Device is new and has not been configured.
Device has corrupt configuration and is unable to operate.
3 Sensor Fault Device has problem with the particulate sensor and needs
immediate replacement.
N/A N/A Locate LED used for maintenance.
5 Time Fault Internal Time base needs updating.
6 Communication Fault Device has failed to communicate to SLC and cannot function properly.
7 Aspirator Fault Indicates the fan has stopped working and requires immediate attention.
8 Filter Fault Device filter is clogged and requires replacement.
Device filter is clogged and has not been replaced 72 hours after giving the
Filter Fault with Minor Fault Relay set.
9 Isolate Fault Device has been disabled.
10 High Flow Fault Device has Increased airflow.
11 Low Voltage Fault Device Input voltage is low.
12 Isolate Fault Device is in isolate mode
TABLE 5. FAULT DESCRIPTION
FAULTS
Whenever a fault occurs, the general FAULT indicator illuminates amber and
the flow status bar oscillates between flow status (green) and a detailed fault
status (amber). Table 5 shows the number, name, description and the acti-
vated relay for each fault. The fault display on the user interface is shown in
Figure 13.
REAL–TIME CLOCK
The unit is equipped with a real-time clock and power supply that allows the
FAAST system to maintain the date and time for up to 72 hours after a loss
of power. Date and time are configured through PipeIQ. The real-time clock
is used to maintain a time base for the device. This time base is used to time
stamp all log entries. If the device loses power for more than 72 hours the
device sets the TIME fault indicating the time needs to be updated.
LOGS
Event Log
The FAAST system is equipped with internal memory that can be configured
to log detector events. Up to 18,000 events can be stored. Events that are
tracked include alarms, faults and user actions. Event tracking data may be
accessed via the network through the PipeIQ software or the Web server in-
terface. Configuration and management of the log are done using the PipeIQ
software.

Data Trend Log
The FAAST system tracks trend data for each 24 hour time period, up to 1
year. The device records the minimum, maximum and average reading of the
sensor for each day.
Message Log
The message log allows the user to enter generic text messages into the sys-
tem’s memory. Messages may be retrieved for viewing at a later time. These
messages may be used to track service history, configuration changes, etc. A
maximum of 300 messages may be stored.
ETHERNET CONNECTION
The FAAST system is a network capable device that is compatible with standard
Ethernet networking equipment. Connectivity is provided by an onboard RJ-45
connector located on the bottom of the unit, as shown in Figure 14. Once initial
setup is complete, the Ethernet connection provides optional remote access, mon-
itoring and e-mail notification through the unit’s Web server and SMTP client.
PIPE NETWORK
The unit can monitor up to 8,000 sq.ft. (approx. 743 sq. m) with a properly
designed pipe network. The pipe network must be properly configured using
the PipeIQ software. The pipe network accommodates a maximum single pipe
length of 262 ft. (80 m). If two branches are used, the maximum single pipe
length is 165 ft. (50 m). The device is capable of both metric 25 mm and IPS
1.05 in. pipe outside diameters without the use of an adaptor. The internal
pipe diameter can range from .591-.827 inches (15-21mm). Only 1 inlet and 1
outlet pipe are used at a time. Pipe networks may be constructed of various
materials such as ABS, cPVC, PVC, copper or stainless steel pipe. Travel time
from the furthest hole depends on the application of the device, but is limited
to a maximum of 120 seconds by the PipeIQ software. Refer to local agency
requirements and PipeIQ software for proper configuration.
