following change percentage of the detection full scale: 0.01%,
0.05%, 0.1%, 0.2%, 0.5%, 1%, 2%, 5%
When the log mode “RATE” is selected the following function
sets the following log rate in seconds: 1, 10, 60, 300, 600,
1200, 1800, 3600
Note: For the smoke change, the detection full scale is the
bargraph full scale, which is the same as Fire 1 Level. For the
flow change it’s 200%, the maximum flow reading in
percentage.

17 Scale Mean Period rt. 15 480 60 This value is the period used to calculate the mean of smoke
background level in this period. The mean period is selectable
between the following values in minute: 15, 60, 12, 240, 480

Sensitivity
Mode 1
S1. 0.1 10.0 1.0 Setting this function to increase or decrease the smoke
detection sensitivity by multiple this value to the original
smoke alarm thresholds when relevant GPI is activated. This
setting must work with the GPI which is set to Sensitivity
Mode 1 or 2. If this function value is set to be greater than 1.0,
the smoke detection becomes more sensitive. On the other
hand, it becomes less sensitive if this function value is set to
less than 1.0.
This function is usually used when different smoke detection
sensitivity is required in certain situations. For example, in
work hours the smoke background level increases due to all
kinds of production activities. It may be desirable to have
lower sensitivity in work hours and have higher sensitivity in
non-working hours. Or when there’re pollutants outside the
detection zone causing false alarms, it can be solved by
decrease the sensitivity by using another ASD device to detect
the pollutant level and connect its relay to the GPI of
the ASD device in the detection zone.
