Polarity Reversal and City Tie Module (Model PR-300) Terminal Connections
Wire as shown below in Figure 23 using proper wire gauges. For more information see Appendix C: Module
Specifications and Features on page 57.
For use in the U.S.A., the installer must add an Atlantic Scientific (Tel. 407-725-8000) Model #24544 Protective
Device, or similar UL-Listed QVRG Secondary Protector, as shown. For use in Canada, the protective device is still
recommended, but the PR-300 may be connected directly to polarity reversal or city tie wiring.
Figure 23 Polarity Reversal and City Tie Module Terminal Connections
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.
The terminal blocks are "depluggable" for ease of wiring.
Notes:
1. Plug PR-300 ribbon cable (P1) into connector (P2) of the main fire alarm module.
2. Cut jumper (JW1) on the PR-300 module in order to transmit a trouble condition to the monitoring
station.
3. Remove jumper plug from jumper JW4 on the main fire alarm module.
4. The polarity reversal interface is power limited and must use type FPL, FPLR, or FPLP power
limited cable.
5. For polarity reversal operation, short tie the city tie connection.
