Fire Development Stages
Fire Stage Time Elapsed Primary Detection System Detection Timing Remarks
Incipient Stage < 1 minute Arc Detection Sensor Within 1 second Early suppression at ignition source
Growth Stage 1~3 minutes Flame·Smoke·Heat Detectors During active fire spread High risk of multiple casualties
Fully Developed Stage ≥ 3~4 minutes Sprinkler System Large-scale fire condition Transition to structural firefighting
Next-Generation Fire Prevention Technology – Arc Detection Sensor
  • Most fires originate during the incipient stage, where invisible electrical arcs or sparks occur before visible flames develop.
  • During this early phase, conventional fire protection systems—such as smoke detectors, heat detectors, and sprinkler systems—typically activate only after the fire has progressed to the growth stage, when flames and smoke are already present.
  • PowerCubeSemi’s Arc Detection Sensor overcomes these limitations by detecting the root cause of electrical fires within one second, enabling immediate intervention before fire escalation.
Technology Principle
  • DUV Sensing Technology
    Proprietary Ga₂O₃-based DUV sensor detects sub-260 nm emissions generated by electrical arcs.
  • Fast Response
    Detects electrical arcs within one second to enable immediate power interruption.
  • Detection Coverage
    Reliably senses micro electrical arcs up to 5 meters with a wide ±60° detection angle.
  • High-Reliability Design
    Ensures stable operation under extreme temperatures, humidity, dust, and vibration conditions.
