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.
