Wire PR-300 Polarity Reversal and City Tie Module (if used) as shown in Figure 40 below.
Power Limited cable type FPL, FPLR or FPLP must be used.
For USA installation, the installer must use Atlantic Scientific (Tel: 407-725-8000), Model

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-4000 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.
