System Sensor RRS-MOD Reversing Relay/Synchronization Module for i3 Series Detectors with Built-in Sounder

Ensure reliable, synchronized audible notification across your i3 detector loops with the System Sensor RRS-MOD reversing relay/synchronization module. Designed for fire and security professionals, this module activates all i3 sounders on a loop when any individual sounder alarms and synchronizes their output—delivering a clear, compliant alarm signal for monitoring, surveillance, and life-safety systems. The RRS-MOD supports both 2- and 4-wire i3 Series detectors and operates on standard 12/24V systems, making it an ideal relay solution for retrofit and new installations. A field-selectable switch accommodates coded or continuous alarm signals and the module works with bell/alarm, alarm relay, or NAC outputs to match your control panel configuration. Installation is straightforward with Velcro mounting and a quick-connect harness that reduces wiring time and cabinet clutter. Backed by a 3-year limited warranty and designed for harsh environments up to 131°F (55°C), the RRS-MOD helps maintain system uptime and compliance. Add this System Sensor reversing relay to your next fire alarm or security project to improve alarm clarity and streamline panel integration.
