It is important that the time and date be set up correctly
on the controller’s internal calendar/clock because it uses
this information to store events in the event log.

not be affected to prevent from unwanted network error.

Setting the reference detector address number between
1 and 250 to enable referencing. When this function is
set to 0 the referencing is disabled.

100
The value set with this function is the percentage
reference signal subtracted from the detector’s signal, if a
reference device has been allocated.

This value is the delay time (in seconds) between a build

the pollution being seen by the detector.

Y
Setting this function to Y enables the smoke/flow log.
There are two selectable log modes, CHANGE and RATE.
On VDOT-ASD-400, 0 is CHAGNGE and 1 is RATE. When
the log mode “CHANGE” is selected the following
change function sets the 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.

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,

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
