Lumexus is an intelligent life-safety system that detects and verifies threats, issues building-wide response and guidance, and shares live event information across response parties. The system is built on a family of connected signs, code-compliant exit signs plus supplemental, entrance, and intersection signs, each equipped with a camera, microphone, speaker, LEDs, and strobes. Events enter through automated detection (gunshot detection, fire alarm integration, camera alerts), a wake word, or wearable fobs. Every alert is reviewed by a 24/7 operations center; once verified, the operator initiates the response defined in the facility’s emergency response plan, and the system executes it: signs display color-coded states with patterned strobes and green routing arrows, and location-specific audio instructs occupants based on the scenario and their position. The system integrates with fire panels, access control, cameras, PA, and mass messaging, and delivers a live incident map to emergency communications centers and responders through RapidSOS.
