5000-103

The Simplex 5000-103 (F-5000) is a reflective auto-aligning infrared optical beam smoke detector system designed for large open spaces like warehouses, atriums, and high-ceiling areas where spot detectors are impractical.
It consists of one detector head, controller, and prism (expandable to two heads), using a single infrared beam reflected by the prism with microprocessor-based signal analysis for early smoke obscuration detection.
