As above.
OUTPUT GAS OUTPUT
In this mode, the line will operate as an Open-Collector output that will activate when the average
reading of the values relating to the 4-20 mA gas detector, connected to the I/O lines of the
selected zones, exceeds the set level.
Silenceable
As above.
Inverted
As above.
Analog
This option is available for the first four zones on the motherboard only; if
selected, the output will operate as a PWM (Pulse Width Modulation) output
with a period of 0.5 s and a Duty Cycle of:
• 0%, if the average smoke reading is less or equal to the "Level 1" setting
• 100%, if the average smoke reading is more or equal to the "Level 2"
setting
• proportional to the average reading, if it is between the two set levels
If the output is set as “Analog” and is equipped with an external filter, it can
be used to control an inverter that activates a ventilator whose speeds will be
proportionate to the average smoke reading.
INPUT FIRE ALARM
The line will operate as a fire detection line. Activation of the line will generate a fire alarm. The
line will remain active until the control panel resets.
Pre-alarm
If “YES” is selected, a pre-alarm signal will be sent when the line activates
and will last for the duration set for the zone concerned.
NightPrealarm
If this option is enabled, the line will signal pre-alarm conditions even when
the system is operating in Night Mode (the Pre-alarm feature must also be
enabled).
Filtered
If “YES” is selected, alarms or faults on the I/O line will be signaled only when
the conditions persist for longer than the “Filter Time” of the zone concerned.
INPUT GAS 4-20mA
In this mode, the I/O line will operate as a gas detection line for gas detectors with 4-20mA
output. If a detector exceeds the pre-alarm threshold, it will generate a gas pre-alarm signal. If
the current output drops below the pre-alarm threshold, the signal will clear. If a detector exceeds
the alarm threshold, it will generate a gas alarm signal.
Modify levels
Position the cursor on this option then press
Ok
to access the detection line
threshold-adjustment wizard (refer to
Chapter 10 - Detection line threshold-
adjustment
for details).
Reset.Alarm
If you select "Yes", alarm signalling will cease when the value returns below
the set threshold; otherwise alarm signalling will persist until the next reset
operation occurs.
Filtered
As above.

String for the selection of the unit of measurement used for reading detection values.
Passing
If this option is enabled, the line will be activated with no alarm signalling;
useful for CO gas detection in parking areas.
INPUT DISABLE-
MENTS
In this mode, the I/O line operates as a supervised input line that when activated bypasses the
zones specified in the lines that follow (all zones with “YES”).
Filtered
As above.
INPUT CLASS
CHANGE
During this operating mode, the I/O line will operate as a supervised output which when activated
will not provide any data on the display but will activate the “Class Change” signal for the zones
specified below (all zone set as “YES”). In this way it will be possible to activate al the outputs that
are set up to activate the “Class Change” signal of the respective zones. This function is useful in
school building installations, where the alarm bells can be activated manually in order to signal
the end of a lesson.
Filtered
As above.
NAC on CC
If you select "Yes", each time the "Change Class" signal activates, the Alarm
NAC output on the panel will also activate.
