Kidde IO-SDC1 1-Loop Fire Alarm Expansion Module 125 Detector

The Edwards IO-SDC1 is a single-loop expansion module designed to extend the detection capacity of compatible Edwards fire alarm systems. Intended for professional commercial and industrial life-safety installations, it allows system integrators and fire alarm technicians to add a dedicated detector loop to an existing Edwards panel infrastructure without replacing the core control equipment. This type of expansion module is a foundational building block in scalable fire alarm architectures, enabling facilities to grow their detection coverage as occupancy needs or code requirements evolve. By adding loop capacity at the module level, installers gain flexibility in system layout, cable routing, and zone organization — all of which are critical considerations in retrofit projects, phased construction, and large-campus deployments. The IO-SDC1 is a genuine Edwards component, ensuring full compatibility and consistent performance within Edwards-based system environments.
