Automatic fire-suppression devices designed to detect and extinguish fires without manual operation. They’re compact fire extinguishers that use a dry powder agent and a thermal activation mechanism so they operate on their own when a fire starts.

Automatic Activation

  • The unit contains dry ABC fire-extinguishing powder (typically ammonium phosphate-based).
  • When the device is exposed to flames or heat above a certain threshold(≈50–60°C), it activates automatically and releases the powder rapidly to suppress the fire.
  • This makes it ideal in situations where a fire could start without immediate human response
  • Broad Fire Class Protection

These devices are generally effective on multiple classes of fire:

    • Class A: Ordinary combustibles (wood, paper)
    • Class B: Flammable liquids (oils, fuel)
    • Class C: Electrical fires and some models also cover vehicle and kitchen fire risks like Class E and F.
