Virtually unknown to historians-yet central to urban risk management-fire-alarm technology emerged as a material contract between authoritarianism and liberalism in the nineteenth century. Unlike most histories of risk that do not analyze the design and use of risk technologies, this study unpacks how such technologies embody norms and structure governance. Highlights: Advanced life-safety platform delivers power, flexibility, and high speed network connectivity - Simplex led. All Simplex addressable control units rely on TrueAlarm addressable detectors. The fire alarm telegraph, hailed by contemporaries as revolutionary technology in the nineteenth century, offers detailed insight into the technopolitics of risk, a yet uncharted territory. With scalable architecture and future-proof design, the 4100ES is ideal for medium to large facilities and multi-building campus style networks.
