DanBi 3000 Series

Electrical Interlock Systems for Commercial Kitchen Hoods

Application: Commercial kitchen fire suppression and ventilation control

How It Works

The DanBi 3000 Series uses a programmable microprocessor to monitor temperature under the hood, exhaust fan status, make-up fan operation, and electrical circuits. The system provides automated control for normal operation and maintenance while ensuring proper fire suppression response.

Key Functions:

  • Fire Suppression Integration – Automatically engages the hood exhaust fan and deactivates the make-up air unit and electrical circuits when fire suppression activates
  • Appliance Interlock – Automatically activates the ventilation system when cooking appliances are turned on
  • Fire Alarm Integration – Connects kitchen fire suppression to building alarm systems
  • Audible Alerts – Provides required alarm notifications

Safety Risks Addressed

Kitchen fires require an immediate, coordinated response. Without proper interlocking:

  • Make-up air can fuel fires by providing oxygen
  • Energized electrical equipment adds fuel to electrical fires
  • Inactive exhaust fans allow dangerous smoke and fumes to spread throughout the building

Regulatory Compliance

NFPA 17A and NFPA 96 Requirements:

  • Hood exhaust fan engagement upon fire suppression activation
  • Make-up air unit and electrical equipment deactivation during fire events
  • Audible alarm activation
