2. Check the voltage at the connector. Make sure it is within the
required voltage range.
3. If the voltage is within the specified range, connect the power
connector to the unit.
4. Close and secure the housing door; verify the fan starts up and
air flows out of the exhaust port. The unit takes 1-3 minutes to
initialise and stabilise in normal mode.
Configuring Other Options
To change any of the default options, it will be necessary to
connect the detector to a PC/laptop with the PipeIQLT software
installed; see USB connection section later in this guide for
more information on this (and the FAAST LT Advanced Setup and
Control Guide).
EXTERNAL RESET
The default setting for the configurable external input is Device
Reset (terminal block T8). A short circuit connection between these
terminals will cause the FAAST LT unit to perform a reset.
