1. An antimicrobial system, comprising:
a luminaire configured to emit a disinfection light via a disinfection light source in an ultraviolet (UV) band for disinfecting a vicinity of a physical space of a target pathogen that is exposed to the disinfection light,
a switching device that includes a primary relay pack, wherein the primary relay pack includes:
a primary relay pack regulator coupled to the luminaire and configured to control power to the luminaire,
a primary relay pack processor coupled to the primary relay pack regulator and configured to control the primary relay pack regulator,
a primary relay pack measurement circuit coupled to the luminaire, the primary relay pack regulator, and the primary relay pack processor, wherein the primary relay power pack monitoring circuit is configured to monitor a power parameter of the luminaire;
a primary relay pack memory accessible to the primary relay pack processor, wherein the primary relay pack memory includes:
(a) an active disinfection threshold for active disinfection operation of the luminaire during which the disinfection light source is on and actively disinfecting the vicinity of the physical space,
(b) a passive operation threshold for a passive operation of the luminaire during which the disinfection light source is off and not disinfecting the vicinity of the physical space, or
(c) a combination thereof; and
disinfection monitoring programming in the primary relay pack memory;
wherein execution of the disinfection monitoring programming by the primary relay pack processor configures the primary relay pack to perform functions, including functions to:
monitor, via the primary relay pack measurement circuit, the power parameter of the luminaire;
compare the monitored power parameter with: (a) the active disinfection threshold, (b) the passive operation threshold, or (c) the combination thereof; and
in response to the comparison:
(a) determine (i) that the disinfection light source is unexpectedly on, (ii) the disinfection light source is degraded or disabled, or (iii) the luminaire is inoperable; or
(b) control power to the luminaire to emit the disinfection light via the primary relay pack regulator.
