Remote triggering of a fire extinguishing operation in a fire zone of a propulsion system

An assembly for an aircraft propulsion system, the assembly comprising:

• a nacelle extending around a longitudinal axis and configured to be disposed around the aircraft propulsion system, the nacelle comprising an internal face that delimits, with an external face of the aircraft propulsion system, a fire zone;
• an extinguisher configured to extinguish a fire in the fire zone, the extinguisher comprising a tank for containing an extinguishing agent, and a spraying nozzle configured to spray the extinguishing agent out of the tank and into the fire zone;
• an activation device for activating the extinguisher;
• and
• a control unit that transmits a control order to the activation device, the activation device receiving the control order transmitted by the control unit and transmitting an activation order to the extinguisher based on the control order, the activation order activating the extinguisher so as to cause the expulsion of the extinguishing agent via the nozzle,
• wherein the extinguisher is mounted on the nacelle;
• and
• wherein the assembly includes at least one of the following elements for transmitting the control order from the control unit to the activation device:
• a wireless communication means between the control unit and the activation device;
• or
• a cable connecting the control unit and the activation device, and a system for detecting an unplugged state of the cable.
