Curtain Detector SATEL CD-2 (white) – dual-zone infrared beam sensor for intrusion detection

SATEL CD-2 (white) is a curtain-style infrared beam detector designed for narrow-area intrusion monitoring. The compact unit creates two closely spaced detection zones that form a focused curtain of infrared coverage, enabling reliable detection of passage or crossing through windows, doorways, display cases and narrow corridors. The detector is intended for integration with alarm and access control systems to provide perimeter or interior protection where a slim profile and directional sensing are required.

Advantages

The detector offers precise curtain-type detection with two infrared zones, reducing false alarms from wide-area movement while sensitively detecting intrusions across a narrow plane. Its compact white housing allows discreet mounting on frames and trim. The sensor provides straightforward integration with standard alarm inputs and supports alignment and mounting adjustments for accurate beam placement. The unit’s focused coverage makes it suitable for applications where a slim detection profile and predictable sensing area are important.

Suitable for

• Protecting windows and glass fronts
• Monitoring doorways and narrow passages
• Securing display cabinets and shelving openings
• Perimeter detection in corridors and confined spaces

Key specifications

• Detection type: curtain-style infrared beam sensor with two detection zones
• Coverage: narrow, directional infrared curtain for close-range intrusion detection
• Color: white housing for discreet installation
• Mounting: compact design suitable for frame- and trim-mounting in confined areas
• Compatibility: designed for connection to alarm and access control systems

How to use

Mount the detector on the frame, trim or wall so that the infrared beams align across the opening to be monitored. Adjust the unit’s position and alignment until the two detection zones form the required curtain over the protected area. Connect the detector to the alarm control panel or input module following the manufacturer’s wiring diagram and ensure correct polarity and tamper connections where applicable. After installation, perform functional testing by passing through the protected zone to verify consistent triggering and adjust sensitivity or alignment if necessary.

Usage recommendations

Install the detector at a height and angle that avoid direct exposure to sunlight or reflective surfaces which can affect infrared beam performance. For display cases or glass-protected openings, secure the unit inside the frame or behind trim to reduce the risk of accidental obstruction. Regularly test and clean the sensor window to maintain reliable detection, and follow the alarm system manufacturer’s guidelines for wiring and end-of-line supervision.
