Mesh networks are only approved for burglary alarm signals and not approved by NFPA 72 for transmitting commercial fire alarms.

• A. FALSE
• B. TRUE
• C. Not approved for any alarm type
• D. Approved for both burglar and fire alarms

Answer: (A)

Mesh networks can be used to transmit alarm signals, including fire alarms, as long as the network path is listed for fire signaling and approved by the authority having jurisdiction. NFPA 72 recognizes multiple signaling paths beyond traditional wired lines, including wireless and IP-based networks, provided the equipment and installation meet the code’s requirements for reliability, redundancy, and security. The statement is false because NFPA 72 does not restrict mesh networks to burglar alarms only; they can be approved for commercial fire alarm signaling when properly listed and AHJ-approved.
