Which organization sets the standard for service loop length at copper wire terminations in alarm systems?

• A. NFPA
• B. OSHA
• C. ANSI
• D. IEC

Answer: (A)

NFPA sets the rules for alarm system installation practices, including how copper conductors are terminated and how service loops should be handled. In the U.S., fire alarm standards are published in codes like NFPA 72 (the National Fire Alarm and Signaling Code), and jurisdictions adopt these guidelines to ensure reliable, safe wiring and testing. Other organizations don’t prescribe these specific installation details for alarm systems in this context: OSHA focuses on general workplace safety, ANSI covers broader standardization, and IEC is international. So the organization that sets the standard for service loop length at copper wire terminations in alarm systems is NFPA.
