SIM-INTL

The Edwards SIM-INTL is an interface module designed to connect conventional detection zones to addressable Signature Loop fire alarm control panels, enabling hybrid system expansion with legacy conventional devices.
It provides a single supervised Class B initiating device circuit (IDC) with intelligent signal processing, supporting conventional smoke detectors, heat detectors, pull stations, or waterflow switches while maintaining Signature protocol communication.
