Chapter 5: Accounting for Bumper Rails 42
Vertical Bumpers and Ball Wall
Bumper systems such as Brunswick’s Ball Wall & Pinball Wizard and AMF’s Duralane raise the bumper rail up
from the gutter (or tilt the whole gutter in the case of Ball Wall). Therefore it is important that the Duo Camera Module
be high enough so that the raised bumper rail does not cut the beam from the Ball Detector.
Where Vertical bumpers have been installed on the lanes, securely attach the Duo Camera Module directly to
the capping, which has been secured in Chapter 4 above. Make sure that a ball will cut the ball detector beam when
it is in the gutter.
AMF Horizontal swing out type
Horizontal Bumpers. The only exception to the above steps is in the situation where swing out type bumpers in
installed. In this case, there is usually a gap between the existing bumper rails, which are used as an area for older
scoring scanners. A section of capping must be removed and packing timber must be secured to the sub timbers in
order for the Duo unit to be mounted at the correct height. Make sure that a ball will cut the ball detector beam when it
is in the gutter. See Chapter 4 for more information on the packing timber needed and removing a section of capping.
