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 flow indicator will turn from yellow to green. Then
release the RESET button and the FAULT LED will go green. The
far left flow indicator will blink green indicating that the device is
ready for the first digit of the pass-code >
Set digit 1 > Using the DISABLE button, click to increment the first
pass-code digit (indicated as flashing yellow on the smoke level
LEDs) and then press TEST when correct. The far left flashing
airflow LED will turn solid green and the next segment LED will
begin to flash, 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 confirm it, enter the next 3
digits of the pass-code. After each digit is accepted, the respective
airflow LED will turn solid green and the following segment LED
will begin to flash, indicating that the device is ready for the next
digit. When the fourth digit is accepted, all 4 airflow 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 flashes 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 flow 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 flow LED per channel will be on
green. With a well set up system the flow 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 flow
LEDs which turn on or flash 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.
