System Sensor EDH100ACDCLP Fire Alarm Duct Detector represents a professional-grade sensing solution engineered to identify smoke presence within HVAC duct systems. This device utilizes advanced photoelectric detection technology to ensure reliable air monitoring and rapid response in commercial fire safety applications.

Airflow Velocity Range: 100 to 4,000 feet per minute

Operating Temperature Range: -4 to 158 degrees Fahrenheit

Housing Protection Rating: NEMA 4/4X/12 compliant

Power Supply Compatibility: 24V AC/DC or 120/240V AC

Sampling Tube Length: 1.5 to 12 feet configurable

Compared to legacy duct detection units, the System Sensor EDH100ACDCLP offers significantly improved tolerance for extreme environmental conditions and variable airflow speeds. While older models often required separate housing kits for weatherproofing, this current iteration integrates robust protection directly into the design, streamlining installation and reducing the total hardware footprint for facility managers.

Advanced Detection Engineering and Performance

The EDH100ACDCLP utilizes a sophisticated, high-sensitivity photoelectric chamber that distinguishes between nuisance particles and actual combustion byproducts with high precision. This ensures that HVAC systems can be shut down promptly during an emergency to prevent the spread of toxic smoke through building ventilation paths.

Built for durability in demanding industrial environments, the unit features a wide operating temperature window that allows for installation in varied mechanical spaces ranging from freezing basements to high-heat rooftop units. By maintaining consistent functionality across these extremes, the hardware provides persistent safety compliance for life-safety systems.

The unit supports field-selectable sampling tubes, allowing installers to customize the reach of the detector based on specific duct dimensions. This versatility, combined with universal voltage support, makes it an ideal replacement for older, single-voltage sensors that may no longer meet contemporary building fire safety standards.
