Automatic Door Opener locations - Vestibule doors

[designer82]

I need to add automatic door openers for the vestibule doors. My question is, does one push plate open both doors or do you need two push plates (one for each door).

Lastly, where would be the best location for the push plates (see picture below).

You will want separate door operators and push plates for each door. Opening both the exterior and interior doors of the vestibule at the same time defeats the purpose of the vestibule as the outside air can freely enter your conditioned space.
