Does the EBDK Need All Sense Feeds to Fail Before Panic is Triggered?

Situation

My EBDK is using a three phase normal sense feed. How does the EBDK know when to activate the emergency look? 

Explanation

When using a three phase normal sense feed only ONE phase needs to sense loss of normal power (using a dry contact closure) for the EBDK to enter panic mode.
