UNDERVOLTAGE PROTECTION
In the version powered at 10..15VDC, when the supply
voltage drops below 10V, the emission of smoke will be
inhibited.
Similarly, the emission of smoke will be inhibited when the
battery is too low to guarantee correct device operation.
INPUTS
CSI
Override
. When active, it drives the immediate
smoke triggering, regardless of the status of the
other inputs and the infrared sensor.
SI
System state
. When active it enables NUBI 4.0
to trigger smoke according to the state of the
ALL-IN
input and the infrared sensor when
present. It is usually connected to the
armed/disarmed state of the alarm system.
ALL IN
System alarm
. When the
SI
input is not active,
the
ALL-IN
input will have no effect. When
SI
is
active
ALL-IN
will produce the following effect:
1) Without PIR or PIR disabled:
NUBI 4.0 will trigger smoke when the
ALL-IN
input goes to active state.
2) With PIR:
NUBI 4.0 triggers smoke when both the activity
of the
ALL-IN
input and that of the infrared
sensor are detected in a 15-minute window,
regardless of who activated first.
OUTPUTS
24H
Tamper clear contact
ALL
OUT
Output active for 90 seconds starting from when
NUBI 4.0 starts to trigger smoke.
BL/IR
Active output when the device has a fault and
therefore is not ready to deliver smoke. With DIP
SW5 ON it takes on the meaning of "
device
ready
". The output is programmable in devices
with infrared sensor, as better described below.
