Method and system of automatically modifying a rate of filling an air bottle with breathable air in a firefighter air replenishment system based on flow rate detection thereof

A method of a safety system of a structure having a fixed piping system implemented within the structure to supply breathable air from a source at a fill rate at which an air bottle is fillable with the breathable air, comprising:

• detecting a flow rate of the breathable air from the source;
• in accordance with the detection of the flow rate, automatically modifying the fill rate;
• and
• filling the air bottle through the safety system with the breathable air at the automatically modified fill rate of the breathable air.

A safety system of a structure, comprising:

• a source of breathable air;
• a fixed piping system installed within the structure for supply of the breathable air across the safety system;
• an air fill charge rate controller device coupled to the breathable air from the source in the safety system;
• and
• a flow sensor associated with the air fill charge rate controller device to detect a flow rate of the breathable air from the source of the breathable air,
• wherein the air fill charge rate controller device comprises a control unit to, in accordance with the detection of the flow rate, automatically modify a fill rate at which an air bottle is to be filled with the breathable air.
