(54)	Low voltage modular room ionization system

(57) A room ionization system includes a plurality of emitter modules (24), each including an electrical ionizer. The emitter modules are spaced around the room and are connected in a daisy-chain manner to a system controller (28). Each emitter module has an individual address for allowing the system controller or a remote control transmitter (30) to individually address and control each emitter module. Electrical lines (26) containing both power and communication lines connect the plurality of emitter modules with the system controller.
