This value is the delay time (in seconds) between a build up of pollution being seen by the reference (if
used) and the pollution being seen by the detector.
1.1.1 Reset, Test & Isolate Button Enable/Disable (Yes/No - Detectors 000-127)
Setup Menu > Front Panel
The front panel buttons may be enabled or disabled individually for the Command Module or Standard
Detectors by setting these functions to
Yes or No .
1.1.1 Power Save Enable (Yes/No - Addresses 001-127)
Setup Menu > Power Checks
This function allows the detector to minimise electrical power consumption when operating from stand-by
batteries. If enabled, upon mains supply failure the aspirator will reduce speed to minimum, regardless of
the user-defined value. This function may be disabled if the minimum aspirator speed increases transport
time unacceptably. (See section 185619544.01.1.1 ”Aspirator Speed (Numeric - Address 001-127)” on
page 21).
NOTE: When in this condition, any smoke reading above 3 bar graph segments on the detector will
automatically remove this condition.
This function has no effect on the Command Module.
1.1.1 Battery Check Enable (Yes/No - Address 000-127)
Setup Menu > Power Checks
If no battery back-up is required, this function should be set to No to avoid Battery fault being
displayed on the front panel. If a back-up battery is used, it is recommended that the battery check be
enabled. When this is done the user will be prompted for an input terminal to use. The battery fault will
be displayed when this contact is open. The default setting is battery fault enabled on "I/P 1". section
185619544.01.1.1 “Detector Terminal Block Connections” on page 33 and section 185619544.01.1.1
“Command Module Terminal Block Connections” on page 34 show the input terminal connections for the
Standard Detector and Command Module respectively.
1.1.1 Mains Check Enable (Yes/No - Address 000-127)
Setup Menu > Power Checks
The FIRElink-400 detector and Command Module are capable of signalling power supply faults from the
power supply where this is equipped with a fault relay (the power supply fitted by default has this feature).
The mains check is disabled by default. If the user sets this function to
Yes , the user will be prompted
with an unassigned input terminal to use (this will normally be "I/P 2" if battery check is already enabled
on "I/P 1" - see section 185619544.01.1.1 “Battery Check Enable (Yes/No - Address 000-127)” on page
21). The mains fault will be displayed when this contact is open.
1.1.1 Aspirator Speed (Numeric - Address 001-127)
Setup Menu > Air Flow
The value entered sets the aspirator in the detector to one of a range of predetermined speeds. The
lower the number entered the lower the airflow rate and the lower the power consumption.
1.1.1 Flow Setup (Yes/No - Address 001-127)
