Which condition is NOT required for using speakers from an emergency voice/alarm communications system for non-fire use?

The use of speakers from an emergency voice/alarm communications system for non-fire applications requires compliance with several important conditions to ensure safety and proper functionality. When addressing the requirement for audio level outputs to be reduced for non-emergency signals, this condition is not mandated for such use.

Speakers in emergency systems must be configured to provide clear, audible alerts during emergencies and meet specific sound output requirements to perform effectively. When these speakers are utilized for non-fire applications, the general requirement to keep or adjust audio levels does not apply. Rather, speakers can emit normal volume levels that are appropriate for the context of the non-emergency communication, rather than being limited to a reduced output strictly for emergency signals.

In contrast, the other conditions are indeed necessary. Monitoring integrity ensures that speakers remain functional and compliant at all times, approval by the Authority Having Jurisdiction (AHJ) ensures that any modifications align with local codes and regulations, and preventing tampering is essential to maintain reliability and effectiveness of the system in both emergency and non-emergency scenarios. Thus, condition surrounding audio level adjustment is not a necessary requirement.
