Antimicrobial system with distributed user authenticated disinfection controls and authenticated safe lockout protocol

Abstract

Antimicrobial system including a luminaire configured to emit a disinfection light in an ultraviolet band for disinfecting a vicinity of a target pathogen. A switching device that includes a primary relay pack. A control station, an arming switch, a room sensor, and a security challenge device. The security challenge device has a communication interface, an operator interface to receive a security challenge input from an operator, a processor, and security challenge device programming in a memory. Execution of the security challenge device programming by processor configures the security challenge device to perform the following functions. Receive the security challenge input from the operator via the operator interface. In response to receiving the security challenge input, generate a security challenge response signal. Send, via the communication interface, the security challenge response signal to enable the primary relay pack to control power to the luminaire to emit the disinfection light.
