ABSTRACT:
The discharge apparatus is used in conjunction with a fire suppression system and includes a plurality of gas cartridges communicating with one or more fire extinguishing tanks. The discharge apparatus includes a first cylinder-piston device which upon activation punctures a diaphragm of a gas cartridge. Gas released from the first gas cartridge pressurizes a related fire extinguishing tanks to cause extinguishing chemicals to be discharged. A small portion of the gas released from the first gas cartridge is responsible for the activation of a second cylinder-piston device associated with a second gas cartridge to cause the release of gas. The gas released from the second gas cartridge pressurizes a related fire extinguishing tank to cause extinguishing chemical to be discharged.
