I MPORTANT N OTE :
The Dual PPI does NOT support the following legacy features contained in the 69255-001 Page/Party ®
Interface (PPI) PCBA:
• “Control Area PPI” Board Type. The Dual PPI may only report as a “Field Area PPI” or as a “Dual
PPI”
• RS-485 communication line
• Party line 1 supervision via DTMF tone detection
Hardware Configuration
Switch and Jumper Settings
Overview
Several switch and jumper settings are required for proper operation of the Dual PPI. The following
settings are set during the system commissioning and programming and should not be changed. If
replacing an existing Dual PPI for maintenance purposes, be sure to replicate the switch and jumper
setting of the card being replaced. Refer to Figure 1 on page 10 for the switch and jumper locations.
Board Address Rotary Switch (SW1) Settings
This switch is used in conjunction with SW4 Position 1 to determine the board addresses used by the
MCU to access the Dual PPI. Since the Dual PPI provides access to two distinct Page/Party
®
zones, the
Dual PPI occupies two separate board addresses – one for Zone A and one for Zone B (assuming that
Zone B is enabled). The board addresses for Zone A and Zone B are defined below (expressed as
hexadecimal values):
Zone A Board Address
Board Address Example: 2 A 0
/ / /----------Always zero
Equals 2 when SW4 Position 1 is OPEN--------------/ /
Equals 0 when SW4 Position 1 is CLOSED----------/ /
/
Set by SW1----------------------------------------------------------------/
Zone B Board Address
Board Address Example: 3 A 0
/ / /----------Always zero
Equals 3 when SW4 Position 1 is OPEN--------------/ /
Equals 1 when SW4 Position 1 is CLOSED----------/ /
/
Set by SW1----------------------------------------------------------------/
Please note that if Zone B is disabled (SW4 Position 2 is CLOSED), then the Dual PPI will only occupy
the Zone A board address (the Zone B board address would then be available for use by other cards in the
card rack).
