Answer:
The DS-K3Y411X utilizes 6 pairs of infrared light detectors to enforce single-passage anti-tailgating and detect intrusion, reverse passing, and barrier climbing. Driven by an electric brush motor rated for an MCBF exceeding 3 million cycles, it features anti-pinch safety and automatic fire alarm linkage.
The Hikvision DS-K3Y411X incorporates specialized optical detection and electromechanical safeguards for high-traffic pedestrian checkpoints:
- Infrared Detection Grid: 6 pairs of IR light detectors per lane monitor pedestrian transit in real time to prevent unauthorized access, detect tailgating, flag reverse passage, and identify climbing attempts.
- Anti-Pinch Protection: If physical obstruction or nipping is detected during closure, the acrylic wings automatically stop or open to prevent injury.
- Alarm Indicators: An audible buzzer and integrated LED lane indicators immediately signal intrusion, unauthorized directional passage, or system faults.
- Emergency Fire Alarm Linkage: When connected to a facility fire system via IO input, triggering the fire alarm causes the barriers to automatically retract and remain open for emergency egress.
- Drive Mechanism & Longevity: Driven by an electric brush motor mechanism engineered for an MCBF (Mean Cycles Between Failures) greater than 3,000,000 operations, supporting throughput rates of 20 to 60 persons per minute depending on authentication speed.
