Sorry, I just reread your post, it's a maglock, not an electric strike.

Yes, you could install a keyswitch on the mag to cut the power or a programmed schedule.

I'm not familiar with the series 200 and it appears it is discontinued. Some software has the ability to program in a latching sequence. For example, a certain swipe card/tag would unlock the mag and leave it unlocked until that card/tag is used again.
