Polarity Reversal and City Tie Module (Model:PR-5100) Terminal Connections

See Appendix C on page 37 for module specifi cations. Wire as shown in Figure 15 below using proper wire gauges. Refer to
LT-877POT for more details.
Note that for use in the USA, the installer must add an Atlantic Scientifi c (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-5100 may be connected directly to polarity reversal and city tie wiring.

If UDACT-9100 and PR-5100 are used then

Protector not needed. UDACT-9100 has integral protector and PR-5100 is plugged into it.

Notes:

The terminal blocks are “depluggable” for ease of wiring.

The city tie interface is

not power limited.

Use either the PR-5100’s City Tie or Reverse Polarity Interface Module - not both.

Figure 15: PR-5100 Polarity Reversal and City Tie Module Terminal Connections

When wiring devices, please keep in mind the following:

Plug PR-5100 ribbon cable (P1) into the main fi re alarm module.

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.
