Fire protective signaling circuits at terminal and junction locations should be identified in a way that prevents what during testing and servicing?

• A. Theft or vandalism
• B. Unintentional interference during testing and servicing
• C. Mislabeling of components
• D. Damage to wiring

Answer: (B)

Clear identification of fire signaling circuits at terminal and junction points is essential so technicians can work without unintentionally affecting the wrong circuit during testing and servicing. When circuits are clearly labeled, a technician knows exactly which path to test or disconnect, reducing the risk of cross-connection, accidental disconnection, or triggering other circuits unintentionally. This preserves the integrity of the system and helps ensure accurate testing results and safe maintenance.

Security against theft or vandalism is a separate concern, and while labeling is important, it isn’t the primary purpose in this testing context. Mislabeling can happen, but the primary goal here is to prevent interference with other circuits during maintenance. Physical damage to wiring is addressed more by proper handling and protection rather than identification alone.
