Simplex 4100-1248 Module NAC Expansion 100W Amplifier 6 Class B
An expansion NAC module that adds six additional Class B notification appliance circuits (NACs) to a 100W amplifier, doubling the available NAC channels while maintaining the 100W power budget.
Key Features:
• Six Additional NACs: Extends NAC capacity from 6 to 12 total circuits when used with primary 100W amplifier module
• Class B Circuit Ratings: Each NAC rated at 1.5 A, 50 W, or 100 speakers maximum for flexible speaker load distribution
• Shared Power Budget: All NACs share the 100W total amplifier power; expansion modules increase circuit count, not available power
• Modular Design: Mounts directly on 100W amplifier assembly for compact system integration and simplified installation
• Voice/Alarm Capable: Supports emergency voice and alarm communications with flexible NAC wiring options
• 4100 Series Compatible: Works with 4100U and 4100ES fire alarm control panels with integrated voice evacuation systems
