MS Sedco DH-400 FRM-AI Combination Motion & Presence Sensor for Automatic Doors

MS Sedco DH-400 FRM-AI Combination Motion & Presence Sensor for Automatic Doors

The MS Sedco DH-400 is a high-mount active infrared (AI) combination motion and presence sensor engineered to deliver safety protection for automatic swinging, sliding, and folding doors. Utilizing Floor Reflection Method Active Infrared (FRM-AI) technology, the DH-400 projects up to 60 individual detection zones precisely reflected off the floor in a rectangular pattern, meeting and exceeding ANSI A156.10 guidelines. The sensor provides detection coverage as far as 13.1 feet (4m) from the door while simultaneously maintaining a dense presence detection zone at the door threshold, and can be mounted at heights up to 13.1' (4m). With a fully adjustable detection pattern width and depth, the DH-400 delivers the highest density sensing pattern available for commercial automatic door applications.

Key Features

• FRM-AI Technology: Floor Reflection Method Active Infrared (FRM-AI) detection uses up to 60 individual floor-reflected detection zones arranged in a precise rectangular pattern for maximum coverage reliability.
• Extended Detection Range: Provides motion detection as far as 13.1 feet (4m) from the door, enabling early activation and enhanced safety for approaching users.
• High-Density Presence Detection: 60 separate detection zones create the highest density sensing pattern available, ensuring continuous presence detection at the door threshold.
• High-Mount Capability: Designed for overhead mounting at heights up to 13.1' (4m), accommodating a wide range of door frame and header configurations.
• Fully Adjustable Detection Pattern: Width and depth of the detection pattern are fully adjustable, allowing precise customization to match specific door opening dimensions and traffic flow requirements.
• Automatic Door Compatibility: Engineered specifically for safety protection on automatic swinging, sliding, and folding door systems in commercial environments.
• ANSI A156.10 Compliance: Detection pattern meets and exceeds ANSI A156.10 guidelines, ensuring code-compliant performance for automatic door safety applications.
• Easy Installation & Adjustment: Designed for straightforward installation and on-site adjustment, reducing setup time and simplifying field configuration.
