PASSWORD ACCESS TO MAINTENANCE MODE
Start PW > Set digit 1 > üOK > Set digit 2 > üOK > Set digit 3
> üOK > Set digit 4 > üOK > Maintenance mode
Start PW process > Press RESET button for 2s. Power LED will
blink red, the left ow indicator will turn from yellow to green. Then
release the RESET button and the FAULT LED will go green. The
far left ow indicator will blink green indicating that the device is
ready for the rst digit of the pass-code >
Set digit 1 > Using the DISABLE button, click to increment the rst
pass-code digit (indicated as ashing yellow on the smoke level
LEDs) and then press TEST when correct. The far left ashing
airow LED will turn solid green and the next segment LED will
begin to ash, indicating that the device is ready for the second
digit of the pass-code >
Set digits 2, 3 & 4 > Again, using the DISABLE button to set the
number followed by the TEST button to conrm it, enter the next 3
digits of the pass-code. After each digit is accepted, the respective
airow LED will turn solid green and the following segment LED
will begin to ash, indicating that the device is ready for the next
digit. When the fourth digit is accepted, all 4 airow segments are
turned off.
Pass-code correct > If the pass-code is accepted, the FAULT
indicator will remain on green and the unit enters Maintenance
mode.
Pass-code wrong > If the pass-code is entered incorrectly, the
FAULT indicator ashes yellow and the unit remains in Normal
mode.
Should no button be pressed for 10s during the password
sequence, the unit returns to Normal mode.
Note: The factory default pass-code is 3111.
To enter the Remote Maintenance mode, see the later section.

FAAST LT DEVICE OPERATION
Power on Sequence
The following turn on sequence is normal operation (using factory
default settings).
At switch on, the power LED on a stand-alone unit turns on green
and the initialisation LEDs turn on yellow. On a loop-base unit, the
power LED switches on green and then turns yellow, signifying
initialisation. The fan will start and stop, then ramp up through
its speeds (audible but no visual indication). At the end of the
sequence the initialise LEDs turn off (reverts to green on the loop-
based unit) and if everything is normal, one ow LED per channel
will turn on green. The whole process takes about 3 minutes.
Normal Operation
In normal operation the front panel LEDs should be indicating as
follows (device with default settings):
Power LED on green and one ow LED per channel will be on
green. With a well set up system the ow indicator should be
around the central point in the curve.
Troubles
Errors, faults, alerts and warnings will set the general fault indicator
on yellow. Additional information may be displayed on the ow
LEDs which turn on or ash yellow. Hi/lo supply voltage problems
are indicated on the power fault LED.
For more information see the FAAST LT ALERTS AND FAULTS
section.
Operating Modes
When powered, the detector can be in one of 6 operating states.
● Initialisation – after a power on or reset the detector re-
calibrates itself.
● Normal – in smoke detection mode following a successful
initialisation.
● Maintenance or Remote Maintenance – an engineering
state, passcode protected.
