The RRS-MOD reversing relay/synchronization module enhances the operation of 2- and 4-wire i3™ Series detectors equipped with a sounder.

Installation ease. The RRS-MOD reversing relay/synchronization module includes a Velcro® attachment for easy installation into the fire alarm control panel cabinet. A quick-connect harness and colorcoded wires simplify connections. Intelligence.

The RRS-MOD module’s design is flexible to accommodate virtually any application. It is compatible with both 2- and 4-wire i3 Series detectors operating over 12 V and 24 V systems. The module can be used with either bell/alarm, alarm relay, or NAC outputs, and its field selectable switch accommodates both coded and continuous alarm signals. Instant inspection.

To meet fire alarm requirements, the RRS-MOD reversing relay/synchronization module activates all i3 sounders on a loop when an individual sounder alarms. Additionally, it synchronizes the output of the i3 sounders, regardless of whether the panel’s alarm signal is continuous or coded, to ensure a clear alarm signal.
