Curtain motion detector SATEL CD-2 DG (dark grey) — SATEL CD-2-DG

The SATEL CD-2 DG is a curtain-style motion detector in dark grey designed to provide narrow, focused volumetric detection for alarm and security systems. It creates a slim detection curtain that monitors movement along doors, windows, corridors and display areas, allowing targeted protection of vulnerable entry lines or exposed glass. The detector is intended for integration with compatible control panels and signal processing modules to form part of a larger intrusion detection system while helping to reduce false alarms by concentrating sensing within a defined zone.

Advantages

The device offers a compact profile and a directional detection pattern that minimizes coverage outside the protected plane. Its focused curtain beam improves detection of crossing or sliding motion while limiting sensitivity to movements behind or far to the sides. The dark grey housing supports discreet installation in interiors where a subdued appearance is desired. Designed for wired connection to alarm systems, the detector is suitable for installations requiring precise placement and reliable performance.

Suitable for

• Protection of entry lines along doors and windows
• Monitoring narrow corridors and passageways
• Securing display cases and shopfronts
• Supplementing volumetric sensors to reduce false alarms in complex layouts

Key specifications

• Casing colour: dark grey
• Detection type: curtain / narrow volumetric detection
• Intended use: indoor perimeter and line protection
• Mounting: wall or frame mounting oriented to create a slim detection curtain
• Connection: wired integration with compatible alarm control panels
• Design features: directional sensing pattern for focused coverage

How to use

Install the detector at the appropriate height and orientation so the narrow detection curtain covers the targeted line (for example along a door or window frame). Connect wiring to the alarm system or control panel following the panel manufacturer’s connection and configuration guidelines. Adjust the detector alignment during commissioning to ensure the curtain intersects the expected intrusion path while avoiding unwanted coverage of distant movement. Test the detector operation through the control panel to confirm correct alarm reporting and sensitivity within the intended zone.

Usage recommendations

Place the detector where its curtain will not be obstructed by furniture, signage or decorative elements. Avoid mounting opposite large glass panes with strong reflections or near heat sources that could affect sensor performance. Use the CD-2 DG in combination with other sensor types and proper zoning within the alarm system to achieve reliable detection and reduced false alarms.
