Exchange of ALARM relay.
It is active about 40 seconds after smoke has been detected.
Act on jumper S7 in order to set the exchange C/NC or C/NO.
Exchange of FAULT relay.
It's active about 1 minute after the beam has detected a sudden
decrease of the signal under the minimum level.
N
Act on jumper S8 to set the exchange C/NC or C/NO.
It activates as the alarm relay. This output allows the direct connection of
the beam to one line of conventional fire control unit. During alarm the
resistence charge is 680 ohm.
Supplying positive 12 V
Supplying negative
Serial door for connection to optional module BR100
Module to visualize the signal:
–
during normal working, the display will visualize the unit values while the
Led bar will visualize the decimanl values of the signal received.
–
during alarm condition the letter A is visualized.
–
during fault condition the letter F is visualized.
-
during calibration the display visualizes the unit values whilst the Leds bar
visualizes the decimal values of signal received.

The terminal board is made of
two separate groups: the one
on the left concerns alarm and
fault-condition output whilst the
one on the right concerns
supplying input and serial door.
