l Holidays: The settings used to define a holiday period. Use the dropdown calendars to choose the
start and end times of the holiday (or break) period. Night time thresholds are used during the holiday
period.
5.5.7 Airflow Options
The Airflow options provide the ability to set:
l limits for what the detector considers to be normal airflow behavior for the sampling pipe network
l which pipe inlets are being used
l aspirator speed
These settings should be confirmed in the ASPIRE design of the sampling pipe network.
Note: Refer to Section 5.6 for the default settings.
Figure5-18: Airflow Options
The Airflow configuration options are as follows:
l Air Flow: The air flow conditions, as a percentage of the normalized air flow, that will cause a fault to be
reported. If the installation site flow conditions vary significantly, it is recommended that the Major High
and Major Low parameters are set closer to their limits.
l Major High: The level of air flow considered to be so far above normal as to require urgent attention.
l Minor High: The level of air flow considered to be above normal but not urgent.
l Minor Low: The level of air flow considered to be below normal but not urgent.
l Major Low: The level of air flow considered to be so far below normal as to require urgent attention.
l Significant Flow Change: The amount of airflow change at which an event is recorded in the event log.
l Delay: The length of time between the air flow fault threshold being reached and the fault relay operation.
l Valve Test: The time interval between automatic tests of the scanning valves.
l Pipes in Use: The pipes that are actually being used. Refer to Section 3.3 on page 15 for further
information.
l Aspirator: Select the required Aspirator Speed setting 1 through 10, as determined using ASPIRE.
