Wire the DVA-500A with either or both the 4 wire E&M jack and/or the 2 wire ring trip jack as shown above. When
using the 4 wire E&M, the ring trip interface may be used for remote programming. The E&M functions will resume
when programming is finished.
Note: The DVA-500A requires a 24 hour unswitched 115V AC outlet. To protect the internal electronics, the
installation of a surge protector is recommended.
