OCB-656 – Curtain PIR Motion Detector
Wall-Mounted Infrared Sensor with Anti-Tamper Switch

The OCB-656 is an indoor curtain-type PIR motion detector designed for access control and door monitoring applications. Controlled directly by the access control panel, it enables hands-free door unlocking or shunting, improving user flow while maintaining security.

Its narrow curtain detection pattern, combined with infrared sensing and DSP processing, significantly reduces false “Door Forced Open” alarms, making it ideal for professional installations where precision and reliability are critical.

Product Features

• Hands-Free Operation – No push buttons required
• Panel-Controlled Activation – Operates directly via the access control system
• Curtain PIR Detection – Narrow detection zone for precise door coverage
• DSP Processing – Minimizes false alarms caused by environmental noise
• Anti-Tamper Switch – Detects unauthorized removal or manipulation
• Wall-Mounted Design – Fast and clean indoor installation
• Relay Output – Supports direct integration with door controllers

Professional Applications

• Access control door automation
• Door forced-open alarm prevention
• Offices, commercial buildings, and secure indoor areas
• Hands-free entry systems for controlled access points

The OCB-656 provides accurate, curtain-style motion detection for access control doors, combining DSP intelligence, anti-tamper protection, and relay output for reliable professional use.
