On the input lines of the device it is capable of generating Contact ID messages and
transmitting them by the ascending edge (L
→
H) and descending (H
→
L) edge. (The number
of the current input is signed here by’x’
).
The length of the time frame can be configured by the
IDELAY
in 20 msec steps, which is
enabled
by default for the inputs to the ascending and descending edges without inverting in
an 500 msec time frame (here the delay value is 25 * 20msec).
The edges can be
enabled/disabled
by the
IxLHEN
(low-to-high) and
IxHLEN
(high-to-low)
parameters for every input line. The
direction
of the
edge detection
(ascending, descending)
can be reversed by the
IxINV
(as NO= Normal Open, NC=Normal Close) parameter.
At this time, the ascending and descending edges are filtered through a time frame (the
inputs must be hold for a minimal interval in the current status, to perform the further status
change while the change is acknowledged).
The
IxARM
parameter is for granting that the current input line can transmit signal only in
Armed
status (value is
Armed
), or whether it is useful to transmit every status changes
–
even in
Disarmed
status (value is
24 hours
). The
armed
value is used for window & door
detectors/sensors by classic, the
24 hours
arming is capable of protecting the secured zones
–
as protecting the front door in
night mode.
The
end of line resistor
can be configured by the
IxEOL
parameter for the current input, to
detect cable wiring cut (sabotage detection feature). It generates alarm at every case.
