Using Smoke Power Reversal Module

The 333PRM Polarity Reversing Module is used to reverse the polarity of the positive and negative voltages powering smoke detectors. The module is for use with 4-wire smoke detectors that employ a sounder and voltage-reversing feature. The module is triggered by a pulsing bell output.

Smoke Detectors Compatible with the 333PRM

The 333PRM may be used with the System Sensor 2112/24AT and similar models with the required operating features previously stated.

The 333PRM reverses polarity to smoke detectors with Integral Temp-3 Sounders. Typically, in alarm, each draws 49-60mA of current. The control panel supplies only enough current for one smoke detector. In order to attach more than one, an external power supply and an external relay may be required.

Installing the 333PRM

Mount the 333PRM inside the control panel’s cabinet or in a separate cabinet using the double-sided tape provided. Wire the 333PRM as shown in Figures 3-12,3-13 or 3-14.Refer to the 333PRM Installation Instructions for detailed information on the installation of the module.
