LED signalling

FA100 provides signals via the LEDs on the user interface, located above the LCD display on the lid (Description of parts, [E]), referring to the entire system or to the single aspirator and detection line ( and ).

Further information is provided by the LEDs that motherboard is equipped with (Description of the PCB, [J]).

icon

colour

ON solid

blinking

green

The device is functioning.

-

yellow

The primary power supply or the auxiliary power supply (if enabled by programming) are lower than the minimum nominal value.

-

yellow

The LED signals faults relating to the entire device:

  • Blower fault (the blower has stopped or does not rotate at the set speed)

  • Communication fault on the addressable control panel loop

  • Programming data corruption

  • Device in service mode

-

green

Indicates that the detector module to which the icon refers is enabled and operating properly.

-

yellow

Indicates a fault with the relevant detector module or related pipe:

  • Module fault (smoke detection error, flow measurement error, module not present or communication loss, etc.).

  • Aspiration flow fault: high flow (pipe breakage) or low flow (obstruction)

  • Detector bypass

-

red

Indicates that the level of smoke detected by the module to which the icon refers exceeds the alarm threshold.

Indicates that the smoke level detected by the smoke module exceeds the warning threshold.

LOOP

yellow

If the “Automatic LED management” option is enabled on the control panel and one of the following faults is present:

  • Motherboard communication fault

  • Isolator open.

  • Sampling chamber fault

  • Remote output monitoring fault
