Tips on Using a Dual PPI to Replace Two 69255-001 PPI Boards
• The first step that should be performed when using a Dual PPI to replace two 69255-001 PPI boards
is to decide which 69255-001 PPI board will be mapped to Zone A of the Dual PPI and which will be
mapped to Zone B. Hereafter, based on this mapping, the two 69255-001 PPI boards will be referred
to as the “Zone A PPI” and “Zone B PPI.”
• When setting the board address for the Dual PPI, use the following conversion table as a guide:
Switch on
Dual PPI Equivalent Switch
on PPI
Notes

Zone B PPI Assigns middle nibble of board address
