3.3 P-500 Alps Reader Mounting Instructions
Three holes need to be drilled to mount the P-500 Reader's electronics package (see
Figure 3:). One large hole (7/8 inch - 22 mm) accommodates the beeper and the reader
cable. Two small pilot holes for a #6 screw (1/8 inch - 3 mm) are for mounting the
electronics package on a wall surface. Drilling is not required if the reader is to be
mounted to a standard U.S. single gang electrical box - the electronics package is
mounted directly to the box.
When mounting to a single gang electrical box, if the box is made of plastic, the
electronics package can be mounted directly to the box. If the box is made of metal, a 1/2
inch thick, plastic spacer is necessary to prevent the metal of the box from interfering with
the reader's read range.
