Front Panel Buttons
The front panel has 3 user buttons: TEST, RESET and DISABLE. 3
These buttons are used to enter the pass-code which then allows

ACTION WARNING OR TROUBLE
ON Red Channel is in alarm (relay is
(Set by panel) set ON with no delay)
1 BLINK Green When sensor is polled
(Polled by panel)
ON Yellow Channel is in pre-alarm
ON Yellow Led number indicates sensor
(Set by panel) alarm level reached
ON Green
BLINK Green Module communication
ON Yellow Common or multiple faults
ON Green FAAST LT is powered
ON Yellow Low power alert / high power

ON Green The LED indicates the air flow
for a channel:
- Centre = normal flow
- Left = flow low;
(-20% at extreme)
- Right = flow high;
(+20% at extreme)

Check the power supply voltage.
On 2 channel unit:
Upper row = Ch1
Lower row = Ch2
Check filter; check pipe network for blockages.
Not used with default settings
Check sensor addresses and installation;
replace sensor.
Try to restart device.
Check filter; check pipe network for blockages;
try to restart device.
Try to restart device.
Returns to Maintenance then Normal operation
after 60min (default)
Flashes all FAULT LEDs; try to restart device.
Check power supply voltage. Try to restart
device
RTC is corrupted or time reading failed.
Check the air flow temperature
Check the air flow temperature
Check the sounder circuit and the EOL
No date set as default
Check pipe network for breaks or leaks.
