How to create Annuciator Combine Element

How to create Annuciator Combine Element

Hi guys,
I wanna create visual annuciator, that if there's a alarm rise from VAR1, the combine element regards with VAR1 will flashing (just like normal element).
The different is this element will not return to normal color even if ACK command is execute. Even VAR1 return to 0, unless operator take some kind of "RESET" action, it'll stay in ALARM state.
It's necessary because, TRIP signal from IED stay active in very short time, we ACK them and it gone away. But operator need to know what kind of signal ALARM in visual view. (Just like physical annuciator does).
Hope you guys can share your thoughts and thank you very much,
Best regards,
