Operating maglocks independent of gate operator

[onandog]

I have a liftmaster LA500 dual swing gate system with maglock. In addition there is a manual pedestrian gate next to it with it's own maglock.

I have 2 Linear keypads (one inside on outside).

Is it possible to program one keypad code to de-energize the maglocks only, and another to de-energize them and open the swing gate?

First code would allow pedestrians to open the pedestrian gate maglock, second code would open the vehicular gate as well.

Thanks for your help,
Oliver
