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 the RPM 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.
