Information About 4100-1315
The 4100-1315 is part of the Simplex 4100 series of amplifiers, developed to provide dependable audio performance for large-scale fire alarm and emergency communication systems. Operating on 120 VAC, 60 Hz, the amplifier delivers a 70.7 VRMS output with 100 watts of power, capable of driving multiple speaker circuits. It features six Class B notification appliance circuits (NACs), each rated for 2A, allowing flexible speaker wiring configurations across large facilities. Designed with redundancy in mind, the unit can be paired with a backup amplifier to provide uninterrupted audio in the event of a failure, ensuring mission-critical communication is maintained. Its built-in power supply, battery backup capability, and real-time supervision functions make the 4100-1315 a robust solution for both emergency and non-emergency applications.
Key Features:
- 100-Watt Output: Provides powerful single-channel audio amplification for large facilities.
- Six Class B NACs: Each rated at 2A maximum, ensuring flexible distribution of speaker circuits.
- Integrated Power Supply: Includes its own power supply with battery backup support.
- Redundant Amplifier Capability: Can be paired with a backup amplifier for continuous operation.
- Expansion Bay Design: Occupies four continuous blocks in a 4100ES expansion bay.
- Adjustable Output Levels: Supports -12 dB and -6 dB settings for non-emergency paging.
- Supervision Features: Continuously monitors input and output levels for fault detection.
- Overcurrent Protection: Built-in protection against overloads and short circuits.
- Standard Power Input: Operates on 120 VAC, 60 Hz for compatibility with building systems.
The 4100-1315 delivers the reliability and precision required for fire alarm voice evacuation and mass notification systems.
