Curtain detector SATEL ACD-220 BR — wireless, brown

The SATEL ACD-220 BR curtain detector is a wireless, brown-finished sensor designed for perimeter protection. It creates a narrow detection zone to monitor windows, doorways and other entry lines, integrating with compatible wireless alarm systems to report motion events. The detector’s focused sensing helps reduce false alarms by limiting coverage to the intended area while maintaining reliable detection along vertical planes.

Advantages

The device provides targeted detection along narrow zones, which helps avoid unnecessary triggering from movement outside the protected line. Wireless communication simplifies installation and placement without the need for running cables. The brown casing allows the sensor to blend with darker frames and interiors. Designed by SATEL, the detector is compatible with systems that support the manufacturer's wireless protocol and uses proven motion sensing optics to detect intrusion attempts at windows and doors.

Suitable for

• Residential windows and balcony doors
• Commercial storefronts and display windows
• Office entry lines and internal partitions
• Perimeter protection in rooms with limited mounting space

Key specifications

• Detection type: curtain / narrow-zone motion detection
• Installation: surface-mounted on vertical frames or walls
• Communication: wireless link to compatible alarm control panels
• Finish: brown housing for discreet integration
• Sensing coverage: narrow vertical detection field focused on entry lines

How to use

Mount the detector at the recommended height beside the window or door so its narrow detection zone covers the targeted entry line. Pair the unit with a compatible wireless alarm control panel following the panel manufacturer’s enrollment procedure. After installation, perform alignment and walk-test along the protected line to verify the sensor detects motion only within the intended zone and to adjust aiming if required. Replace batteries and follow system maintenance routines as specified by the alarm system documentation to ensure continuous operation.

Usage recommendations

Place the detector so that its narrow field faces the expected path of intrusion; avoid pointing it at large open areas to minimize false positives. Use the brown version where visual matching with dark window or door frames is desired. Regularly test the sensor within the overall alarm system and keep the wireless link and battery condition monitored according to the alarm control panel’s guidelines.
