PRM 2W 4W Polarity Reversal Modules Instructions PRM series modules are Polarity Reversal Modules for use with the FSA series of 2 4 wire smoke detectors and smoke alarms with integral sounders These modules a connection such that when one smoke detector goes into alarm smoke detector horns will sound When the control panel is initiated into alarm it the PRM module to reverse the polarity of the power to the connected smoke Upon Power Polarity Reversal all connected smoke detectors will sound integral horn refer to Table 1 Supply Range 12 15VDC Draw Standby PRM 2W 30mA max PRM 4W 10mA Draw In

with FSA 210 series 2 wire smoke detectors with integral horns This includes a Class B Style B 2 wire smoke detector zone which provides an inter for control panels that do not have a compatible 2 wire smoke detector zone of the module to the control panel is a typical 4 wire type where a reset power output and a panel fire zone input is provided The module provides a dry contact as the initiating device for the panel fire zone The module monitors Bell output of the panel to determine when a fire alarm has been initiated in the the module detects a temporal pattern or a pulsing output on the bell circuit will reverse the power to the connected smoke detectors signaling them to sound horns Alternately the module can be triggered to reverse the polarity with a dry from the control panel or from an external relay contact that is activated by an from the control panel see Fig 1 for wiring details This module can be used with FSA 210 series smoke detectors without an integral and thus provide a compatible interface to control panels that do not have a 2 wire smoke detector zone For this application the Polarity Reversal function not be used is for use with the FSA 410 series 4 wire smoke detectors with integral horns module requires resettable power from the control panel The dry contact s in the detectors are wired directly to the fire zone in the control panel module monitors the Bell output of the panel to determine when a fire alarm has initiated in the panel When the module detects a temporal pattern or a pulsing on the bell circuit it will reverse the power to the connected smoke detectors them to sound their horns Alternately the module can be triggered to re the polarity with a dry contact from the control panel or from an external relay that is activated by an output from the control panel 4 wire smoke detectors supervision RM 2 module must be installed beyond the last detector to monitor power to detectors If power fails the RM 2 will open the detection loop and initiate a condition in the control panel for that zone see Fig 2 for wiring details The PRM 4W module is also used with the FSA 410 D series of smoke alarms smoke alarms are only ULC Listed for use in Canada see Fig 3 for wiring details module to control panel and smoke detectors Table 1 and Figure 1 2 or 3 PRM can be mounted directly in the control panel using the three mounting nylon provided PRM xC modules are equipped with a plastic enclosure for exter mounting The plastic enclosure can also be mounted on top of a 2 electrical box metal conduit connections
