What's Up in the Hoistway?

With much change and innovation within today's Elevator Industry including the development of "hi-tech" drives and controllers in the machine room, does the hoistway need to continue to be the "low-tech" environment of any elevator installation? This paper examines the way we approach the data highway, command and communications functions within an elevator control system. It considers how a degree of standardization can still present total installation flexibility and provide both manufacturer and contractor with improved installation performance, and a higher degree of "Safety" through a Pre-Wire or Modular installation concept. It also looks at the changes in "Installed Safety" and the growing requirement for both LSF (Low Smoke & Fume) and HF (Halogen-Free) cable products within the building structure, and the especially within the elevator hoistway.
