'Electrical Room Fire Suppression System Using CO₂' is an automatic fire protection system designed to safeguard electrical panels, switchgear, transformers, control equipment, and other critical electrical installations. The system uses 'Carbon Dioxide (CO₂)' as a clean, electrically non-conductive extinguishing agent that rapidly reduces the oxygen concentration in the protected area to suppress fire without leaving residue or damaging sensitive electrical equipment. Upon detection of fire by the detection system, the CO₂ release mechanism is activated and the gas is discharged through strategically positioned nozzles to achieve effective fire suppression. The system is particularly suitable for electrical rooms where water-based suppression may cause equipment damage. Proper room sealing, detection, alarm, ventilation shutdown, and safety interlocks are essential for safe and effective operation.
