Question 2

Under UL 325 safety standards, how many independent entrapment protection devices are required for a residential swing gate operator?

Accepted Answer

Two

Answer

UL 325 requires a minimum of two independent entrapment protection devices for residential swing gate operators to provide redundant safety.

Question 3

What is the function of a vehicle loop detector embedded in pavement near an automated gate?

Accepted Answer

To detect vehicles using electromagnetic inductance and signal the gate to open or remain open

Answer

Loop detectors generate an electromagnetic field; when a vehicle's metal mass disrupts this field, the detector signals the gate controller to open or hold open.

Question 4

Which gate style is best suited for an opening where limited clearance exists on both sides and a slide gate would not fit?

Accepted Answer

Bi-fold gate operator

Answer

Bi-fold gates fold in half when opening, requiring significantly less horizontal clearance than a comparable slide or swing gate.

Question 5

What voltage is most commonly used to power residential automatic gate operators in the United States?

Accepted Answer

120V AC

Answer

Most residential gate operators are designed to run on standard 120V AC single-phase household current, which is available at a typical residential electrical panel.
