Which NFPA 72 reference number is associated with supervisory signals sub coded in the provided materials?

• A. NFPA 72 - 10.14.3.1
• B. NFPA 72 - 10.14.3.2
• C. NFPA 72 - 23.8.5.4.2
• D. NFPA 72 - A.3.2.2

Answer: (B)

Supervisory signals are conditions monitored by the fire alarm system that require attention but do not initiate a fire alarm. NFPA 72 uses specific subcodes to classify these supervisory events so technicians can distinguish between different supervisory conditions and respond appropriately.

The reference that directly defines how supervisory signals are sub coded in the provided materials is NFPA 72, 10.14.3.2. This subsection is the exact spot the materials point to for the subcoding scheme, which is why it’s the best answer. The other references either deal with different topics or are located in sections that don’t cover the subcoding details for supervisory signals.
