Notes:
• Either the PR-300's city tie or polarity reversal interface may be used, but not both.
• The city tie interface is not power limited.
• Plug PR-300 ribbon cable (P1) into connector (P4) of the FX-2000 main fire alarm module.
• Cut jumper (JW1) on the PR-300 module in order to transmit a trouble condition to the monitoring station.
• Remove jumper plug from jumper JW4 on the main fire alarm module.
• The polarity reversal interface is power limited and must use type FPL, FPLR, or FPLP power limited
cable.
• For polarity reversal operation, short the city tie connection.
