Information About 4100-5125
The 4100-5125 is a Simplex remote power supply (RPS) module developed for use in fire alarm systems requiring distributed 24 VDC power and NAC support. It is designed to operate with AC and battery input provided by a Power Distribution Module (PDM), enabling reliable system power distribution. The unit provides three supervised NACs, configurable for Class A or Class B operation, and supports TrueAlert non-addressable appliances as well as conventional reverse-polarity circuits. With SmartSync technology, the RPS allows audible and visible notification devices to be independently controlled over the same wiring, reducing installation complexity.
Key Features:
- Reliable Power Distribution: Provides regulated 24 VDC output along with integrated battery charging for remote system cabinets.
- Three NAC Outputs: Delivers three supervised notification appliance circuits, configurable as Class A (Style Z) or Class B (Style Y).
- Broad Device Compatibility: Supports Simplex TrueAlert non-addressable devices as well as conventional reverse-polarity appliances.
- SmartSync Technology: Allows audible and visual notification devices to be independently controlled using the same pair of wires.
- Fault Monitoring: Each NAC is supervised for open or short conditions, with automatic isolation of a faulty circuit to maintain overall system operation.
- Short-Circuit Protection: The system prevents activation of shorted NACs during initialization to avoid damage or false activation.
- Seamless Integration: Receives AC and battery power directly from a Power Distribution Module, ensuring dependable system performance.
- UL 864 Compliance: Designed and certified to meet fire alarm safety standards for regulated installations.
- Flexible Deployment: Intended for remote cabinet mounting to extend power and circuit capacity across larger systems.
- Lightweight and Durable: At 10 lbs, it offers easy installation without compromising on robustness.
The 4100-5125 delivers the reliability and precision required for powering and supervising notification circuits in Simplex fire alarm systems.
