I will design commercial fire alarm voice evacuation system and riser cad

Get NFPA 72 compliant commercial fire alarm voice evacuation system design, emergency voice alarm communication (EVACS) layouts, and audio riser CAD schematics for AHJ permit submission. I provide full fire protection engineering, speaker placement, and audio circuit drafting for commercial buildings, assembly occupancies, and high rise facilities.

Technical Services Offered:

• Voice Evacuation Speaker Layout: AutoCAD 2D drafting for ceiling and wall-mount speaker strobes, ambient noise level dBA planning, and intelligibility coverage.
• Audio Riser Diagram CAD: Single line riser schematics, audio circuit loops, notification appliance circuits (NAC), voice control panels (EVAX/FACP), and amplifier module connections.
• Amplifier Sizing & Audio Calculations: Power amplifier wattage calculations, 70V/25V audio line loss analysis, dBA sound level attenuation checks, and battery backup reports.
• Evacuation Zone Matrix: Emergency voice message sequence of operations, phased evacuation logic, cause and effect matrices, and HVAC/fire door integration.
• AHJ Permit & Code Compliance: Systems designed in accordance with NFPA 72, NFPA 70 (NEC), IBC Section 907, and ADA accessibility standards.
