the reason the motor i chose was so flimsy was because i wanted to make 
sure it was easy enough to turn when off, so that it would not hold the 
latch open.

I will probably replace it with a different motor, and a large capacitor 
and relay, so that when it is energized from the intercom it will open the 
lock (while charging the capacitor).

when power from the intercom stops, the relay will release and drain the 
capacitor into the motor in the other direction, so the motor will undo.
