RPM module wiring
The Reverse Polarity Module (RPM) is an interface between the control panel and a reverse
polarity receiver. It provides off-premises signal transmission for systems that must comply
with NFPA requirements. When used as a reverse polarity remote station transmitter, it can be
connected to either a single circuit (alarm or alarm and trouble) or up to three circuits (alarm,
supervisory, and trouble). Below are application diagrams for using the RPM module. For
detailed information and wiring, refer to RPM Reverse Polarity Module Installation Sheet
(P/N 3100430).
Notes
• The RPM must be mounted in conduit, in an MFC-A enclosure, immediately adjacent to the
panel.
• All relays are unsupervised and must be connected to a power-limited source.
