System Sensor i3 Series Detectors
The RRS-MOD, a reversing relay/synchronization module by St. Charles, Ill.-based System Sensor enhances the operation of two- and four-wire i3 Series detectors with a built-in sounder, allowing all the detectors on the loop to sound when one alarms by reversing the polarity to the detector zone, according to the company.
The module also synchronizes all detectors on the loop to ensure a clear, audible signal. The module can be used with bell/alarm, alarm relay or NAC outputs. Its field-selectable switch accommodates both coded and continuous alarm signals.
