Table 2: Wiring Terminal Designations
(Note - Terminals marked CH2 will only be available on 2 channel
models)
Sensor
The sensor address is set on rotary decade
switches on the back of the smoke sensing
devices. The smoke sensors are located under
the sensor cover inside the unit (see Figure 9).
The
Smoke Sensors
section of
Maintenance
- later in the manual - shows how to remove the
sensors. As supplied, the default for channel 1
is Address 1; in 2 channel units (or when two
sensors are fitted) the second device is set to
Address 2.
Module
The module address is set by means of rotary
decade address switches located behind the
door of the unit. Use a screwdriver to rotate the
wheels to the desired address. The selected
address refers to channel 1; on 2 channel
units the device assigns the next (+1) module
address to channel 2 automatically. Hence,
address 159 is not valid for channel 1. (Note:
for control panels that use only 99 addresses,
99 is invalid for channel 1.)
Note:
The module address will only respond to
a panel poll when in
Normal
mode.
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).
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.

RELAY
ACTION:
NOTES
ALARM 1 or 2
Controlled by panel when it determines
alarm condition has been met.
Set ON and OFF by panel; not latched
FAULT 1 or 2
When FAULT CONDITION on Ch1 or Ch2
or a common FAULT occurs. Fault is also
signalled when in Service Mode and when
the device is unpowered.
Fault state is not latched.
SOUNDER 1 or 2
Set ON when a channel is in ALARM.
Sounder 1 corresponds to Ch1 and
Sounder 2 corresponds to Ch2
Default condition = set on in ALARM.
SETTING THE ADDRESSES
Figure 10: Address Switches
X 10
X 1
Each aspiration channel uses loop communications to report its
status information to the CIE (Fire Panel). As a factory default,
the unit will report smoke alarm and sensor information at an
associated sensor address and general alerts and faults on a
different module address.
