POLARITY REVERSAL MODULE (PCB ONLY) FOR 2-WIRE SMOKE DETECTOR INTERCONNECT.
The PRM series modules are Polarity-Reversal Modules for use with the FSA series of 2 and 4 wire smoke detectors and smoke alarms with integral sounders. These modules provide a ‘Tandem’ connection such that when one smoke detector goes into alarm, all smoke detector horns will sound. When the control panel is initiated into alarm, it signals the PRM module to reverse the polarity of the power to the connected smoke detectors. Upon Power Polarity Reversal, all connected smoke detectors will sound their integral horn.
