Which feature is required for Class I Residential Vehicular Gate Operators?

• A. Speed must exceed 2 feet per second
• B. Must sound an audio alarm after two sequential entrapment faults
• C. Must be silent and have no alarms
• D. Entrapment faults can be ignored if the gate is small

Answer: (B)

In Class I residential gate operators, safety signaling for entrapment faults is required. If the safety system detects entrapment faults, the operator must trigger an audible alarm after two sequential faults. This audible alert communicates to bystanders and the operator that a persistent safety issue exists, prompting inspection or service before the gate resumes normal operation. The goal is to reduce the risk of injury by ensuring a fault is clearly noticed and addressed.

The other options don’t fit because this safety signaling is not about rapid or minimum speeds; residential gates have regulated speeds, and insisting that speed must exceed a threshold is unsafe and not a requirement. A system that is silent with no alarms would fail to warn people of faults, violating safety standards. Finally, ignoring entrapment faults, even if the gate is small, would leave a known hazard unaddressed, which standards do not permit.
