Run expression after certain time...

Hello All,
I have an after effects project set up where a layers opacity increases when another object passes over it. I have made this work, however I would like the opacity increase to only happen once over a certain length of time:
Eg. time between effect reset = 20 frames
Frame 100 'Object B' passes over 'Object A'...Object A flashes.
Frame 110 'Object B' passes over 'Object A' again....Object A does nothing.
Frame 125 'Object B' passes over 'Object A' yet again...Object A flashes.
How do I create a countdown or timer which works out when the effect should or shouldnt happen?
Thank you in advance...if you need any more information please let me know....
Best,
