摘要:
Elevator system hall fixtures such as lanterns, hall call button switches and lights, gongs, and floor position indicators are connected to a controller via wireless transceivers. The controller can be a system, group, and/or car controller. A low power wireless system connects all fixtures on one hallway, with a higher power wireless system connecting each hallway with the appropriate controller.
