A control relay or control module must be located within how many feet of the component controlling the emergency control function?

• A. 1 ft
• B. 3 ft
• C. 6 ft
• D. 10 ft

Answer: (B)

The key idea is keeping the control relay or module as physically close as practical to the device that it is controlling, so the emergency function can respond quickly and reliably. Shorter wiring paths reduce resistance, inductance, and potential signal degradation, which helps ensure a fast, predictable activation when the emergency control is triggered.

The correct distance is within three feet. This tight proximity minimizes wiring delays and voltage drop, boosting the reliability of the emergency function.

Distances like one foot, six feet, or ten feet either aren’t the specified maximum in this requirement or would unnecessarily lengthen wiring, increasing the chance of slower or less reliable operation. Staying within three feet keeps the control setup compact and dependable.
