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 integrated arming switch, a room sensor. The integrated arming switch has a communication interface, an integrated room sensor, a processor, and integrated arming switch programming in a memory. Execution of the integrated arming switch programming by processor configures the integrated arming switch to perform the following functions. Based on a second input from the operator, produce a visual inspection signal. In response to the integrated room sensor detecting occupancy of the vicinity of the physical space by the human, produce a room state signal. Send, via the communication interface, the visual inspection signal to enable the primary relay pack to control power to the luminaire to emit the disinfection light.
