models)
POWERING UP
Using Default Settings
1. Connect a suitable 24VDC supply (complying with European
Standard EN 54-4) to pins 1 and 2 on terminal block T1 (See
Table 2)
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).

ACTION:
NOTES
ALARM 1 or 2
Set ON when ALARM CONDITION is met
on a channel
Default condition = Level 1. Alarm state is
latched as default. A manual RESET is
necessary to deactivate LED and relay.
PRE-ALARM 1 or 2
Set ON when PRE-ALARM CONDITION
is met on channel.
Default condition = Level 1.
FAULT 1 or 2
When FAULT CONDITION on Ch1 or Ch2
or a common FAULT occurs. Fault is also
indicated when in SERVICE mode and
when the unit is unpowered.
Fault state is not latched (default)
SOUNDER 1 or 2
Set ON when a channel is in ALARM /
PRE-ALARM. Sounder 1 corresponds to
Ch1 and Sounder 2 corresponds to Ch2
Default condition = set on in ALARM.
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.
