Polarity Reversal and City Tie Module (Model: PR-100) Terminal Connections
See
Appendix C
on page 38 for module specifications. Wire as shown in
Figure 15
below using proper wire gauges.
Note that for use in the USA, the installer
must
add an Atlantic Scientific (Tel. 407-725-8000) Model #24544
Protective Device, or similar ULI-Listed QVRG Secondary Protector, as shown. For use in Canada, the protective
device is still recommended, but the PR-100 may be connected directly to polarity reversal and city tie wiring.
Figure 15: PR-100 Polarity Reversal and City Tie Module Terminal Connections
When wiring devices, please keep in mind the following:
• Plug PR-100 ribbon cable (P1) into the main fire alarm module.
• Cut Jumper (JW!) on the PR-100 module in order to transmit a trouble condition to the monitoring station.
• All circuits are power limited and must use type FPL, FPLR, or FPLP power limited cable.
• For polarity reversal operation, short the city tie connection.
Notes:
• The terminal blocks are “depluggable” for ease of wiring.
• The city tie interface is
not
power limited.
• Use either the PR-100’s City Tie or Reverse Polarity Interface Module--not both.
