Kidde Fire Systems high pressure carbon-dioxide fire suppression systems use liquid carbon 

dioxide agent stored under its own vapor pressure in seamless steel cylinders at ambient 

temperature. Each cylinder is equipped with a valve having a connection for attachment of a 

discharge head. The discharge heads attach to the distribution piping by means of flexible 

hoses or a swivel adapter.

Actuation of the suppression system is initiated by one or more control heads which are 

attached to the control ports on the valve(s) of the pilot cylinder(s). Actuation of the pilot 

cylinders creates sufficient pressure in the discharge manifold to operate the remaining 

cylinders in the system.

Single or dual cylinder suppression systems utilize cylinder straps to secure the storage 

cylinders to walls or other rigid structural members. Specially designed racks are utilized for 

multiple cylinder systems to secure the cylinders, absorb the discharge reactions, and to 

facilitate system servicing and maintenance.

Carbon dioxide agent is stored in steel cylinders as a liquid under its own vapor pressure and 

at ambient temperature. Each cylinder is equipped with a forged brass valve assembly which 

contains a safety disc device (Table 2-1) for protection against over pressurization due to 

elevated temperatures. Each valve is equipped with a side port that serves both as a fill 

connection and as a control port for attachment of system actuators. The control port is 

designed to accept all of the control heads listed in this manual.

The threaded connection on the top of each valve mates with a discharge head to allow agent 

release and distribute the CO

 from the cylinder into the discharge piping.
