Appendix B – Automatic Bumpers 101
Brunswick Automatic Bumpers
Most automatic bumper systems are designed so that they are operated by the closure of a switch contact so
that when the switch is closed, the bumpers go up and when the switch is open the bumpers will go back down.
The one exception to this rule is the Brunswick Automatic Bumper system, which is controlled on a communications
network via a control box under the lanes. The Duo system is able to directly control the Brunswick Bumper
Controller by supplying a LLAN Hub and an additional LLAN cable.
