Edwards SIGA-MCRR

The Edwards SIGA-MCRR Polarity Reversal Relay Module is designed to intelligently control and activate multiple SIGA-AB4G Audible Sounder Bases on a fire alarm loop. By reversing the polarity of its 24 VDC output upon command from the Signature loop controller, it ensures that all connected sounder bases are activated simultaneously. The microprocessor-based intelligence guarantees reliable operation, precise control, and seamless integration with Edwards Signature Series fire alarm systems.

Where It Can Be Used?

The SIGA-MCRR Polarity Reversal Relay Module is commonly used in large commercial, industrial, and institutional buildings where multiple audible alarms need to be reliably controlled. It is ideal for hospitals, schools, high-rise residential buildings, shopping malls, data centres, and other critical facilities that require synchronized alarm signaling. Its compact UIO plug-in design allows for easy integration in single or multi-module installations, providing flexibility for diverse fire safety system layouts.

Edwards SIGA-MCRR Relay Module

The SIGA-MCRR is an intelligent analog-addressable module that provides a Form “C” dry relay contact to reverse the polarity of its 24 VDC output. This function activates all connected SIGA-AB4G Audible Sounder Bases on the loop, enabling group operation of alarms. Designed for UIO plug-in mounting on UIO motherboards, it allows fast, modular installation. Operating on 15.2–19.95 VDC with low standby and active current, the module is energy-efficient and reliable. Built-in LED indicators provide real-time status monitoring, while automatic device mapping and electronic addressing ensure smooth communication with the Signature Series loop controller.
