What are the stated storage pressures for Halon in the system?

• A. 360 psig and 600 psig
• B. 180 psig and 360 psig
• C. 600 psig only
• D. 120 psig and 240 psig

Answer: (A)

Halon is stored in cylinders under pressure, and the design specifies two standard pressures to represent acceptable charge states. For fixed Halon systems, those stated storage pressures are 360 psi and 600 psi. The 600 psi figure matches a fully charged cylinder at typical room temperature, while 360 psi reflects a lower but still acceptable charge that can occur with partial discharge or different temperatures. These two values give the operating range used for inspection and recharge verification.
