Considering that the longer is the protected range, the longer is the beam concerned by smoke,
it would be better to set the sensitivity level according to distance between beam and reflector,
following indications shown in the chart below.

Once calibration is made, take off the adjusting mirror BF TEST before closing with
cover.
The 4 fixing holes on the cover can be "hidden" using the screw-covers given within.
Working Mode "Normal"
Here are the indications given by the three Leds on the left:
–
during normal working: green Led flashes about every 2 seconds, red Led is off, yellow Led
is off.
–
during alarm: as soon as the beam detects presence of smoke, green Led will flash quickly,
red Led and yellow Led will be off. After about 40 seconds if the event causing the alarm continues,
green Led will keep on flashing quickly, red Led will be on and alarm relay will be activated,
yellow Led will be off.
When the event causing the alarm is over, green Led will start again flashing every 2 seconds,
red Led will remain on and alarm relay will remain activated.
The alarm signalling is reset:
–
if the output +F connected to a conventional fire control unit (Jumper S9 closed) has
been used for the alarm signalling, the reset will be automatic resetting the control unit.
–
For all other connection modes (Jumper S9 opened), the reset is made taking off supplying
from barrier for few seconds.
–
In any case, if the module BR100 is used, reset can also be made by use of the mechanical
key on board.
–
In case of fault condition: as soon as the beam detects a sudden drop of signal, green Led
will flash quickly, red Led will be off, yellow Led will flash quickly. After about 1 minute, if the the
event causing it persists, green Led will keep on flashing quickly, yellow Led will be fix on and
concerned relay is activated.
–
Fault signalling is automatically reset as soon as the event stops. The beam is automatically
back in condition of "normal working".
By use of remote module BR100 following indications will be available:
DISPLAY
–
during normal working: a value between 0 and 9 is visualized, corresponding to the signal
received during last calibration (manual or automatic).
–
in case of alarm: letter A is visualized.
–
in case of fault condition: letter F is visualized.
LED BAR
–
presence of a strong reflection: Led 7 or 8 on.
–
during normal working: Led 5 or 6 on.
–
in case of alarm or fault condition : one of the Leds under 5 on.
Ex.: if Led 3 is on, it shows that the signal is lower than 50% compared to the best signal.
