Abstract: A fire suppression system is disclosed. The fire suppression system comprises a first storage cylinder configured for storing a first suppression solution. The system comprises a second storage cylinder operatively connected to the first storage cylinder. The second storage cylinder is configured for storing a second suppression solution, wherein in response to a detection of a fire condition, the first storage cylinder is configured to release the first solution into the second storage cylinder to cause the second solution to be delivered first during a first phase of a discharge.

Abstract: A mechanical time delay apparatus for creating a time delay between a pneumatic inlet for connection to a source of pressurized gas and a pneumatic outlet includes a primary pneumatic flow path from the inlet to the outlet. A movable gate is associated with the primary pneumatic flow path and is movable between an open position and a closed position. The gate is urged by a biasing force to the closed position. In the closed position, the gate is disposed to block a flow of gas through the primary pneumatic flow path. In the open position, the gate permits such flow. The time delay apparatus further includes an accumulation chamber in communication with the gate for a gas pressure within the accumulation chamber to urge the gate against the biasing force to the open position when the gas pressure exceeds a threshold pressure. A secondary pneumatic flow path extends the inlet to the accumulation chamber.
