According to regulations, when optical fiber is used in a fire alarm system, in accordance with which article should these cables be installed?

• A. Article 600
• B. Article 700
• C. Article 770
• D. Article 800

Answer: (C)

The correct choice pertains to Article 770, which specifically addresses the installation and use of optical fiber cables in various applications, including fire alarm systems. Article 770 outlines the standards and safety measures necessary for fiber optic cables to ensure that they are installed in a manner that mitigates fire hazards and promotes reliable communication within fire alarm systems. This article includes guidelines on cable construction, protection against physical damage, and proper routing methods that are essential for maintaining the integrity and functionality of fire alarm systems in the event of a fire. It also specifies requirements for the handling and installation of these fibers to minimize risks, which is critical for compliance with industry standards and ensuring safety in building procedures. The other articles referenced focus on different aspects: Article 600 pertains to the use of motors and generators, Article 700 addresses emergency systems, and Article 800 relates to communications circuits, none of which are specifically relevant to the use and installation of optical fiber cables in fire alarm systems. Thus, Article 770 is the appropriate regulation to reference for this context.
