Product Description

The System Sensor D4120 is a 4-wire photoelectric duct smoke detector designed for challenging conditions. It senses smoke within air ducts using a pivoting housing compatible with both round and rectangular ducts. It operates effectively even with airflow speeds between 100 and 4000 feet per minute, temperatures from -4 to 158 degrees Fahrenheit, and humidity ranges from 0 to 95 percent (non-condensing). The detector's plug-in sensor head offers improved false alarm immunity and easy installation, testing, and maintenance.

  • Pivoting housing for various duct types
  • Effective in extreme conditions
  • Easy installation and maintenance

Product Highlights

This detector's features include a plug-in sensor head for easier maintenance and false alarm immunity, a cover design that isolates the sensor head from the low-flow feature, ample wiring space, and tool-free installation for the patented sampling tube. An interconnect feature allows up to 50 interconnected detectors to relay information. High contrast terminal designations make wiring straightforward, and built-in short circuit protection prevents damage during installation.
