Information About SD505-DUCT

The SD505-DUCT is part of the Silent Knight SD505 series, engineered for integration with addressable fire alarm control panels via a two-wire SLC connection. It features a rugged steel backbox with a clear cover, allowing for visual inspection while protecting internal components in demanding environments. The detector utilizes air sampling tubes to continuously monitor airflow within ducts, ensuring reliable detection across varying duct sizes and air velocities. Designed for compliance with fire safety standards, it is commonly used in HVAC systems to enhance building safety and meet regulatory requirements.

Key Features:

  • Addressable Detection System: Integrates with fire alarm panels via two-wire SLC communication
  • Photoelectric Sensor Technology: Detects smoke particles from combustion with high accuracy
  • Pre-Installed Sensor: Includes SD505-APS analog photoelectric smoke sensor
  • HVAC Duct Monitoring: Designed specifically for air handling and duct applications
  • Air Sampling Tube System: Uses intake and exhaust tubes for continuous airflow monitoring
  • Wide Air Velocity Range: Operates effectively between 300 and 4000 feet per minute
  • LED Alarm Indication: Provides visual status and alarm signaling on the sensor head
  • Heavy-Duty Steel Enclosure: Durable backbox with clear cover for protection and inspection
  • Flexible Installation: Includes mounting template and hardware for quick setup
  • Multiple Tube Options: Supports various duct widths with optional sampling tubes
  • Low Current Consumption: Approximately 0.55 mA in standby and alarm conditions
  • Code Compliance: UL 268A listed and compliant with NFPA 72 and 101 standards

The SD505-DUCT delivers the reliability and precision required for early smoke detection in HVAC duct systems and fire safety applications.
