Does the Alert Engine still check Unmanaged nodes?

I am curious if the Alert Engine checks alerts against nodes that are in a Unmanages status?

I ask because I have several nodes that are now sitting with perpetual alerts on them due to the fact that they were put into an Unmanaged stauts while alerts were triggered on them.

If the alert engine still checks nodes that are in an Unmanaged status then I can just add a condition to my alerts that says "Where Node Status is not equal to Unmanaged", however; if the Alert Engine does not check those nodes then that won't help.

Thanks in advance for the help on this!
