Warning device for a respirator product

A process for indicating a state of warning in a respirator product, wherein the respirator product has a valve, the process comprising the steps of:

• providing a pressurized breathing gas source and a breathing gas supply line connected to the breathing gas source and leading to a user breathing connection;
• providing a scent gas line connected to the pressurized gas source via the valve and connected to the supply line;
• operatively connecting a scent cartridge to the scent gas line;
• releasing a gas flow in the case of a warning into the scent gas line for sending the released gas flow via the scent gas line and connected scent cartridge into the breathing gas supply line and thereby via the user breathing connection into the range of perception of a user connected to the respirator product via the user breathing connection.

A respirator system, comprising:

• a pressurized gas source;
• a breathing air supply line;
• a user connection providing breathing air to a user, the user connection being connected to the supply line;
• a pressure reducer provided between the pressurized gas source and the user connection;
• and
• a warning device comprising a scent gas line connected at a discharge end to said breathing air supply line, a valve connected to said pressurized gas source and connected to said scent gas line, sad valve releasing a gas flow into said supply line via said gas scent line, and a scent cartridge operatively connected to said scent gas line for influencing the scent of the gas flow released by said valve for adding scent to the breathing air in the supply line upon the occurrence of a predetermined state.
