RM-2 Relay Module
Installation Instructions
The RM-2 Relay Module is used as an end-of-line (EOL) power supervision module for
4-wire smoke detectors. The RM-2 is used with the Polarity Reversal Module PRM-
4W and DSC FSA-410 series smoke detectors.
When the PRM-4W reverses polarity on the smoke detector loop to activate all smoke
detector sounders, the RM-2 Relay will continue to operate normally (regardless of
input power polarity). Refer to the PRM-2W/4W Polarity Reversal Module Installation
