What term describes wireless operation of this system?

• A. Limit Switches
• B. Final Limit Switch
• C. Wireless Controls
• D. Directional Limit Switches

Answer: (C)

Wireless operation is described by wireless controls, which means signals are transmitted without physical wiring. In escalators and moving walks, most control circuitry is wired for reliability, but when a system uses wireless controls, commands like start, stop, or remote operation can be sent through radio or other non-wired means instead of through cables. The other terms refer to physical sensing devices that are normally wired into the control system: a final limit switch is a switch that stops the unit at the end of travel, and directional limit switches detect the direction of movement. They describe hardware sensors, not wireless signaling. So the term that best describes wireless operation is wireless controls.
