Course Description: This course will discuss battery calculations when designing fire alarm systems. Focus will be given to notification circuits, including visual and horn/strobe devices as well as an emphasis on proper design fundamentals for voice-based speaker notification circuits. The presenter will include a review on the basics of audibility and related material found in the annex of NFPA 72 ‘National Fire Alarm and Signaling Code’.
Learning Objectives:
• Understand fire alarm system battery calculations
• Explain fundamentals of dB loss for audible designs
• Learn the difference in calculations when designing with audible horn devices versus voice-based speakers.
