diebold deposit safe w/30 min time delay

I'm looking for info regarding a Diebold "chute deposit container" w/30 minute delay.

It has been years since I worked Diebold DATs, but I don't remember them being capable of 30 minutes. Could just be that all the ones I worked on were always 15 minutes. I did recently come across an early S&G timer than can be set on either time. I am familiar with Diebold night depository heads but they can be used with any safe. Maybe a little more info or pictures might get you further.
