Installed CO2 fire suppression system
1of 3 activation stations go to your 2 25 lb CO2 bottles then go to your first pressure switch. This is ur air shut offs, pre discharge light, and 10% of ur siren. Then it hits ur 30 second delay bottle, u can manually by pass this bottle. After the 30 second delay bottle it hits pressure switch number 2 this is ur discharge light.lastly is pressure switch number 3 this is the engine room dampener. And then CO2 is discharged above STBD side MDE
