Alarm Inputs Configuration
This configuration screen will display the quantity of input channels in your DMS-3K model up to
the maximum 128 inputs. The configuration allows you to configure the contact alarm details
and add a input and a unique legend that is used to describe the alarm or normal state. Alarm
Inputs can be connected to the 8 I/O, 16 I, I/R and 8 IAM modules.

Input
The input number is included with every alarm and return to normal event. The default input
number will start at 1. It can be changed to start on any input and will automatically increment
all subsequent input numbers.
Input Number Assignments:
The Alarm Input numbers correspond to the Digital and Analog I/O installed in your system.
Each I/O card is addressed via switch settings to correspond to a group of inputs. For example,
if your system has (4) 16 I Digital Input Modules addressed for the first 4 positions and you start
your inputs at 1, the first module will have inputs 1-16, second module has 17-32, third has 33-
48 and fourth has 49-64.
In systems with Analog Inputs, each Analog Input Channel allocates 4 Alarm Inputs to allow for
4 trip settings. Analog Inputs always start at the beginning of the inputs assigned. In the
example above, if the system had (2) 8 IAM Analog Modules and (4) 16 I Digital Input Modules,
the first 8 IAM Analog Input Module would be assigned inputs 1-32, second 8 IAM module
