ABSTRACT:
A system and apparatus for automatically dispensing a paper product mounted on a gravity-assisted holder through a dispenser. The apparatus includes an electric motor, a main product roller for automatically rolling a predetermined amount of the paper product from the holder, exit guide rollers for guiding the paper product through a front cover of the dispenser, and a series of interconnected gears that are driven by the electric motor to activate the main product roller and exit guide roller and operate both the main roller and exit roller at the same speed. Operating the rollers at the same speed prevents paper or tissue jamming inside the dispenser. The system monitors usage of each paper product dispenser with each dispenser having a microprocessor controller for determining a corresponding paper product status for the dispenser. Each paper product dispenser communicates with a master network device preferably mounted on a ceiling plane. Paper product status messages are transmitted between each dispenser and master network device unit using a standard data communications protocol. The master network device communicates the paper product status for each individual dispenser to an independent building automation and control network. A central control console that is interoperable with the building automation and control network monitors the status of each paper product dispenser through signals communicated from a master receiver/transmitter unit to the central control console.
