MAIN CONNECTOR
GND:
Ground power supply
+12V:
+10..15VDC power supply
24H

ALL
Alarm (OUTPUT)
PIR
PIR movement detection (OUTPUT)
UNDERVOLTAGE ROTECTION
NUBI 4.0 is protected against under voltage. When the
power supply falls below the 10V threshold, the smoke
emission will be inhibited.
This function prevents unwanted smoke emissions when
NUBI 4.0 and the alarm panel use the same power supply
and the alarm panel causes unwanted commands due to a
low supply voltage.
This could happen during a power failure that lasts a long
time and drains the battery below the 10V limit.
INPUTS INTERFACE
When the DIP Switches 1..4 are set to OFF, NUBI inputs
will become active when switched to GND, as shown in the
following table:
CSI
Trigger the smoke delivery when the input is
closed to GND
SI
Burglar system armed when the input is closed to
GND, disarmed when opened.
ALL
Burglar alarm active when the input is closed to
GND.
With the DIP SW1 the inputs reference can be changed
from GND to +12V (+VCC). Using SW2, SW3, SW4 each
input logic can be switched from normally open to normally
closed as shown the following DIP Switches functional
table.
In the event that the inputs are not driven with a clean
contact to GND,
never apply a voltage higher than
+VCC to the input
which would irreversibly damage the
electronic circuit.
