Colour Indication Description
Yellow Warning A steady or flashing LED indicates the following:
A steady LED indicates that detection is aborted
due to a fault (detector cover removed, fan motor,
filter removed, or critical temperature), that there is
a flow high/low range fault, that the module is
disabled, or that the module is in power save mode.
A fast flashing LED indicates that at least one
detector module is in FastLearn mode, that the
module is starting up, or that pipe calibration is in
process.
A slow flashing LED indicates that one or more
devices or features are in test mode or that a
detector is in demo mode.
Green Power A steady LED indicates that the module is powered
up correctly.
[1] Display modules only.
Note: If alarms or faults are latched, then an alarm or fault indication remains
active until a system reset, even if the condition that caused the indication has
ended. If alarms or faults are not latched, the indication disappears when the
corresponding condition ends.
