Information About 4100-3101
The 4100-3101 is part of the Simplex 4100U and 4100ES system platform, serving as the IDNet channel interface that connects detectors, modules, and manual stations on the addressable loop. The module installs directly into the panel’s power distribution interface and communicates with field devices via IDNet signaling. With a communication range of up to 10,000 feet, it ensures stable data transmission across extensive installations. The 4100-3101 is designed for industrial-grade reliability and is UL Listed for fire alarm applications. Though discontinued, it remains a critical component for maintaining existing 4100-series systems, with the 4100-3102 serving as its functional replacement.
Key Features:
- 250-Point Capacity: Supports up to 250 addressable IDNet devices on one loop.
- Panel Compatibility: Designed for use with Simplex 4100ES and 4100U fire alarm control panels.
- Reliable Communication: Digital signaling over a two-wire IDNet SLC loop.
- Extended Wiring Distance: Supports wiring runs up to 10,000 feet.
- Power Supply Integration: Operates from the FACP 24 VDC source with 30–36 VDC IDNet output.
- High Device Density: Ideal for large facilities requiring multiple addressable detection points.
- Compact Design: 4” × 5” plug-in circuit card for efficient space use.
- UL Listed: Certified for fire alarm applications and code compliance.
- Line Tolerance: Handles up to 40 Ohms line resistance and 0.60 μF capacitance.
- Suggested Replacement: Superseded by model 4100-3102 in current production systems.
The 4100-3101 delivers dependable addressable device communication and high capacity for intelligent Simplex 4100-series fire alarm systems.
