PRM-2W/4W Polarity Reversal Modules

Installation Instructions

Introduction

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.

Interconnection of Smoke Detectors

PRM-2W is for use with FSA-210 series 2-wire smoke detectors with integral horns. This

module includes a Class B/Style B 2-wire smoke detector zone which provides an inter-

face for control panels that do not have a compatible 2-wire smoke detector zone.

Connection of the module to the control panel is a typical 4-wire type where a reset-

table power output and a panel fire zone input is provided. The module provides a

N.O. dry contact as the initiating device for the panel fire zone. The module monitors

the Bell output of the panel to determine when a fire alarm has been initiated in the

panel.

When the module detects a temporal pattern, or a pulsing output on the bell circuit,

it will reverse the power to the connected smoke detectors signaling them to sound

their horns. Alternately, the module can be triggered to reverse the polarity with a dry

contact from the control panel or from an external relay contact that is activated by an

output from the control panel (see Fig. 1 for wiring details).

NOTE: This module can be used with FSA-210 series smoke detectors without an integral

horn and thus provide a compatible interface to control panels that do not have a 'com-

patible' 2-wire smoke detector zone. For this application, the Polarity Reversal function

would not be used.

PRM-4W is for use with the FSA-410 series 4-wire smoke detectors with integral horns.

This module requires resettable power from the control panel. The dry contact(s) in the

smoke detectors are wired directly to the fire zone in the control panel.

The module monitors the Bell output of the panel to determine when a fire alarm has

been initiated in the panel. When the module detects a temporal pattern, or a pulsing

output on the bell circuit, it will reverse the power to the connected smoke detectors

signaling them to sound their horns. Alternately, the module can be triggered to re-

verse the polarity with a dry contact from the control panel or from an external relay

contact that is activated by an output from the control panel. 4-wire smoke detectors

require 'power' supervision.

The RM-2 module must be installed beyond the last detector to monitor power to

the detectors. If power fails, the RM-2 will open the detection loop and initiate a

trouble condition in the control panel for that zone (see Fig. 2 for wiring details).

NOTE: The PRM-4W module is also used with the FSA-410(D) series of smoke alarms.

These smoke alarms are only ULC Listed for use in Canada (see Fig. 3 for wiring details).

Installation

Wire module to control panel and smoke detectors (Table 1 and Figure 1, 2 or 3). PRM

modules can be mounted directly in the control panel using the three mounting nylon

standoffs provided. PRM xC modules are equipped with a plastic enclosure for exter-

nal mounting. The plastic enclosure can also be mounted on top of a 2” electrical box

for metal conduit connections. To test the system, activate trigger to verify operation.
