Kidde RELA-EOL End of Line Relay Fire Alarm Device

The Edwards RELA-EOL is a professional-grade end-of-line relay device designed for use within supervised fire alarm notification appliance circuits. As an end-of-line component, it serves the critical function of terminating a supervised circuit while simultaneously providing relay output capability, allowing the panel to continuously monitor circuit integrity for open or short conditions. This dual role — supervision and relay switching — makes it a valued component in commercial and industrial fire alarm installations where circuit reliability and code compliance are paramount. The RELA-EOL is intended for integration with Edwards fire alarm systems, supporting installers in meeting the demands of professional life-safety infrastructure. Its design reflects Edwards' commitment to components that perform consistently in demanding environments, giving system designers, contractors, and authority-having-jurisdiction inspectors confidence in the integrity of the overall notification circuit.
