More Information

🔹 Pressure Switch

(Left – White Box with Red Outlet)

  • Function: Monitors water pressure in fire sprinkler or pump systems. Automatically activates pumps or alarms when pressure drops below a set threshold.
  • Features:
    • Durable housing with clear indicator panel
    • Integrated electrical contacts for control circuits
    • Used in fire pump systems to maintain consistent pressure
    • Ensures reliable operation during emergencies

Brand: Danfoss (as labeled)

🔹 Air Release Valve

(Right – Copper-Colored Valve)

  • Function: Removes trapped air from pipelines, preventing blockages, noise, and reduced flow efficiency.
  • Features:
    • Made of brass for corrosion resistance and durability
    • Automatic operation – releases air when pressure builds up
    • Maintains smooth water flow and prevents cavitation
    • Ideal for fire hydrant systems, sprinklers, and booster pumps
✅ Applications:
  • Fire sprinkler systems
  • Fire pump stations
  • Water supply networks
  • Industrial and commercial buildings

These components work together to ensure safe, efficient, and uninterrupted water flow in emergency situations.

🛡️ Reliability. Safety. Performance.

A fire extinguisher is a portable device filled with extinguishing agents designed to control or extinguish small fires in emergency situati

  • Water / Water Mist – for Class A fires (wood, paper, cloth).

  • Foam – for Class A & B fires (flammable liquids).

  • Dry Powder (ABC Type) – for Class A, B & C fires (solid, liquid, and gas).

  • CO₂ (Carbon Dioxide) – for Class B & electrical fires.

  • Wet Chemical – for Class K/F fires (cooking oil & fat).

An ABC Dry Powder or Foam extinguisher is commonly recommended for homes since they cover multiple fire types.

Follow the PASS technique:

  • Pull the pin.

  • Aim at the fire base.

  • Squeeze the handle.

  • Sweep side to side.

No. Using the wrong extinguisher can worsen the fire. For example, never use a water extinguisher on electrical or oil fires.

  • Wall Brackets & Stands – for safe mounting.

  • Fire Cabinets – protection against weather/damage.

  • Pressure Gauges – to check extinguisher pressure.

  • Safety Pins & Seals – prevent accidental discharge.

  • Refilling Kits – for recharging after use.

  • After every use (even partial discharge).

  • Typically every 5 years (depending on type & local fire regulations).

Yes. Brackets, cabinets, and hoses should be checked regularly for rust, cracks, or wear to ensure the extinguisher is always ready for use.
