Which control is used to move the stairlift to a waiting rider?

• A. AC/DC Motor
• B. Traveling Cable
• C. Riser Calculation
• D. Call/Send Controls

Answer: (D)

Call/send controls are what summon a stairlift to a rider. These controls provide two-way signaling: a call button at the rider’s landing requests the chair to come to that location, and a send button (often used after the rider sits down) directs the chair to return or move to another destination. This setup is what makes it possible to bring the stairlift to a waiting rider and then send it on when needed. Other items like the drive motor supply power to move the chair, the traveling cable carries power and signals along the moving track, and riser calculations are design details unrelated to calling the chair to the rider.
