Exposed fire alarm cables installed on ceilings and sidewalls shall be supported by what?

• A. The permanent building structure
• B. Approved straps
• C. Approved straps every 18 inches
• D. Conduit

Answer: (A)

Exposed fire alarm cables running on ceilings and sidewalls are intended to be secured to a solid, non-movable part of the building. The permanent building structure provides a stable anchor that won’t shift or sag, helping to prevent damage to the cables and ensuring the alarm system remains reliable. While straps or conduit can be used in some installations, the requirement emphasized here is that the primary support for exposed runs is the building’s structure, which anchors the cables securely and maintains proper installation standards. This approach protects the wiring from movement, accidental contact, and wear, supporting long-term system performance.
