At what temperature will the fixed Halon fire extinguisher discharge?

Explanation:
A fixed Halon fire suppression system releases when a heat-sensitive fusible link reaches its melting point. This link is designed to melt at a specific temperature, and when it does, the valve opens and the Halon is discharged into the protected area to suppress the fire. For many aircraft fixed Halon systems, that designated temperature is 174°C. Reaching this heat level indicates a fire hot enough to warrant immediate suppression, so the system discharges promptly. The other temperatures listed aren’t the standard discharge setting for this type of system; they would not trigger discharge under normal operating conditions.
