At what temperature will the fixed halon fire extinguisher automatically discharge?

The fixed halon fire extinguisher is designed to automatically discharge at a specific temperature to ensure prompt response in the event of a fire. The correct discharge temperature of 174 degrees Fahrenheit is set based on the thermal properties of the halon agent and the operational requirements of the aircraft.

This specific temperature ensures that the extinguisher activates in high-risk situations, where a fire could compromise the safety of the aircraft and its occupants. The activation point is critical as it balances the need to avoid false activations from normal operating temperatures while ensuring that the system responds quickly enough to extinguish fires that could escalate quickly.

Other temperature options, although within a reasonable range for potential activation, do not align with the specific design and operational specifications for halon systems used in aircraft, which have been established based on extensive safety testing and regulatory standards.
