Replying to Getting passed Exit Fire doors without setting alarm off?

So did some google searching which turned up nothing. But I was wondering if any of you knew how to get through those alarmed fire exit doors. They say "fire exit door, alarm will sound when pressed wait 15 seconds before door opens."

We're on the inside of the door trying to get to the outside. I'm not trying to cut things open or cut wires or anything just if theres any like credit card tricks? or anything? We spend a shit ton of time until the wee hours of the morning in studio working on projects and it'd be cool if we could find a way to get to the roof to chill.

Someone opened the lower door earlier this week which set off the alarm which we aren't sure whether it notifies anyone (like public safety) it just rang for a while. I was thinking maybe pop the downstairs door and figuring out a way to set the upstairs door so it won't set the alarm off once the lower door is set off?

If anyone has got any ideas or heard any stories about friends finding a way through thatd be dope. Thanks.
