About the alarm template you show: keep in mind that a condition will exclude a line in the alarm template if that condition evaluates to true. Hence, in your example the line will be included, unless all three of 'SDI Input Status A/B/C' are warning.

Reading your original problem, you probably want the condition

• 'SDI Input Status A' is not warning AND
• 'SDI Input Status B' is not warning AND
• 'SDI Input Status C' is not warning

Then you should only get a parameter status (i.e. green or other color bullet) for 'SDI Input Status D' if at least one of 'SDI Input Status A/B/C' is set to warning.

However, as Miguel mentioned, a correlation rule might be more appropriate here. Assuming you want to apply the same rule on multiple elements of the same protocol, you can create a correlation rule as follows: in the alarm filter section filter out the protocol and the parameters you want to apply your rule to

(I don't immediately have your protocol, so I did it on four parameters of some other protocol. You should put 'SDI Input Status A/B/C/D' here.)

Then, you group the resulting alarms per element

Then, add a condition to make sure the rule only applies when there are two or more alarms (on the same element).

Finally, you can then create a new alarm with severity major on the element with the SDI Input Status alarms.
