Which NFPA standard and section covers manual release requirements for discharge in clean agent systems?

• A. NFPA 72 2019, Section 4.3.3.5.1
• B. NFPA 72 2019, Section 21.4.2
• C. NFPA 2001 2018, Section 7.7.2.4
• D. NFPA 2001 2018, Section 4.3.3.5.1

Answer: (D)

The key idea is that manual discharge controls for clean agent systems are defined in the NFPA 2001 standard, not in NFPA 72. In the 2018 edition, the specific guidance you need is found in Section 4.3.3.5.1. This section outlines how a manual release device for discharging the clean agent must be arranged: it should be clearly identified and accessible to authorized personnel, protected against tampering or inadvertent actuation, and properly integrated with the system so that a deliberate manual action initiates discharge while coordinating with alarms and status indications. This ensures safe, intentional discharge and proper interlocking with the overall protection system. NFPA 72 covers fire alarm and signaling aspects, including manual pull stations, but it does not govern the discharge of clean agents. The other NFPA 2001 references point to different topics within the same standard, not the specific manual discharge requirement addressed in 4.3.3.5.1.
