• What is the primary function of an electric gate operator?
• To provide security alarms
• To automate gate opening and closing
• To monitor traffic flow
• To provide lighting
• To automate gate opening and closing

Rationale: The main purpose of an electric gate operator is to allow

gates to open and close automatically, improving convenience and security.**

• Which type of gate is best suited for limited driveway space?
• Swing gate
• Sliding gate
• Bi-fold gate
• Cantilever gate
• Sliding gate

Rationale: Sliding gates require less space to operate since they move

horizontally along a track, making them ideal for tight spaces.**

• Which safety device prevents a gate from closing on a vehicle or

person?

• Limit switch
• Photocell sensor
• Motor brake
• Key switch
• Photocell sensor 1 / 3

Rationale: Photocell sensors detect obstructions in the gate’s path and

prevent it from closing, reducing the risk of accidents.**

• What is the recommended minimum clearance between a gate and the

ground for safety?

• 10 mm
• 50 mm
• 100 mm
• 200 mm
• 50 mm

Rationale: A minimum clearance of 50 mm helps prevent fingers, pets,

or debris from being trapped under the gate.**

• Which type of electric motor is most commonly used in residential gate

operators?

• AC induction motor
• DC motor
• Stepper motor
• Synchronous motor
• DC motor

Rationale: DC motors are popular in residential gate operators due to

their smooth operation, low noise, and ease of control.**

• What is the function of a gate limit switch?
• To detect obstacles
• To control the maximum opening and closing positions
• To provide remote control signal
• To prevent theft
• To control the maximum opening and closing positions

Rationale: Limit switches define the endpoints of the gate’s travel to

prevent overtravel and mechanical damage.**

• Which safety standard governs the installation of electric gates?

A. ISO 9001

B. EN 12453

C. OSHA 1910

D. IEC 60204

B. EN 12453

Rationale: EN 12453 specifies safety requirements for powered gates,

including force limits and safety devices.** 2 / 3

• What is the typical voltage requirement for residential electric gates?

A. 12V AC

B. 24V DC

C. 110V AC

D. 440V AC

B. 24V DC

Rationale: Many residential gate operators use 24V DC for safety and

compatibility with battery backup systems.**

• Which control device allows temporary manual operation during a

power outage?

• Timer switch
• Key switch
• Manual release mechanism
• Motion sensor
• Manual release mechanism

Rationale: The manual release allows the gate to be operated manually

if power is unavailable.**

• What is the primary advantage of a cantilever sliding gate over a

tracked sliding gate?

• Lower cost
• No ground track required
• Easier installation
• Faster opening speed
• No ground track required

Rationale: Cantilever gates are supported by rollers on a cantilevered

track and don’t need a ground track, which reduces maintenance issues.**

• Which component protects the electric motor from overheating?
• Limit switch
• Thermal overload protection
• Photocell sensor
• Control board
• Thermal overload protection

Rationale: Thermal overload protection automatically stops the motor

if it overheats, preventing damage.**

• What is the maximum recommended force for a gate closing on a

person according to safety standards?

• / 3
