    Activates when either pass-through door opens; flush with the wall surface, covered by a static-dissipative PVC lens.

    Infrared beams detect objects placed inside the transfer chamber and can be used to trigger an audible alert. The crossed red lines depict the non-visible trigger lines between the IR transmitters and receivers.
