Over the decades, the A2 pinsetter system from Brunswick® has proven itself to be an absolutely reliable system in thousands of installations around the world. Systems first designed in the 1960's no longer live up to today's safety standards: The machinery is often left exposed in the equipment room, being easily accessible from all sides and not protected against intervention or trespassing by unauthorized persons. These deficiencies can result in accidents involving service technicians as well as players and, on rare occasions, can also lead to fatalities.

With Pauly A2 Safety Guard, Schlosserei Pauly has developed a complete self-monitoring system that wipes out these deficiencies while improving safety to an optimum level for both service personnel and players. During development, care was taken to ensure that game operations would not be disturbed and that unnecessary outages and downtime could be avoided. With its three components, the system makes possible controlled access to the equipment at a maximum level of safety.
