5.1 Input Configuration
This section provides information on input functions and wiring connection.
The inputs 1 to 24 are software configurable to provide flexibility to suit application
requirements. These inputs have factory default setting when shipped.
There is 200ms noise filtering for inputs 1 to 24. When input is activated within 200ms
and then restored back to normal, the activation of this input will be ignored.
5.2 Input Type
Inputs 1 to 24 are analog input designed to detect 4-state events in the “Supervised
Mode”. It may be configured to detect 2-state events in the “Non-Supervised Mode”.
DIP Switch 1- Position 6 “LSS” - ON for supervised mode and OFF for non-supervised
mode.
5.3 Supervised Input
In Supervised Input Mode, the end of line resistors must be used to terminate the line
(refer to Figure 6.1). Line fault conditions can be monitored in addition to the device
status. All these event occurrences are reported to the IBSS management software.
