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
What temperature does the metal rod in the engine room have to reach in order for it to activate the installed fire suppression system?
190°F
Fire extinguishers?
2 5lb CO2
2 10lb PKP
One of each in the survivors comp and enclosed bridge

we fill to 95% so not to over flow. 16 gallons of that is not usable due to the pick up being 2 inches off the deck of the tank. what is the usable fuel?
357 Gal
Fire suppression system: pressure switch 1
activates strobe light inside the engine room, pre discharge light outside of the engine room(color), and shuts off the the engines (solenoids)
Fire suppression system: pressure switch 2
activates discharge light
Fire suppression system: pressure switch 3
mechanical pressure switch that closes air dampener located behind the ladder to the open bridge
Fire suppression system: 3 actuation stations
in between stidd chairs enclosed bridge, outside engine room, on the Co2 bottles in the AUX space.
what do the red, black, and non colored rings on the 24V panel in the AUX space mean
red is component of DDEC, black is non essential, and no color ring means do not secure.
