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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eReliable Power Distribution: Provides regulated 24 VDC output along with integrated battery charging for remote system cabinets.\u003c\/li\u003e\n\u003cli\u003eThree NAC Outputs: Delivers three supervised notification appliance circuits, configurable as Class A (Style Z) or Class B (Style Y).\u003c\/li\u003e\n\u003cli\u003eBroad Device Compatibility: Supports Simplex TrueAlert non-addressable devices as well as conventional reverse-polarity appliances.\u003c\/li\u003e\n\u003cli\u003eSmartSync Technology: Allows audible and visual notification devices to be independently controlled using the same pair of wires.\u003c\/li\u003e\n\u003cli\u003eFault Monitoring: Each NAC is supervised for open or short conditions, with automatic isolation of a faulty circuit to maintain overall system operation.\u003c\/li\u003e\n\u003cli\u003eShort-Circuit Protection: The system prevents activation of shorted NACs during initialization to avoid damage or false activation.\u003c\/li\u003e\n\u003cli\u003eSeamless Integration: Receives AC and battery power directly from a Power Distribution Module, ensuring dependable system performance.\u003c\/li\u003e\n\u003cli\u003eUL 864 Compliance: Designed and certified to meet fire alarm safety standards for regulated installations.\u003c\/li\u003e\n\u003cli\u003eFlexible Deployment: Intended for remote cabinet mounting to extend power and circuit capacity across larger systems.\u003c\/li\u003e\n\u003cli\u003eLightweight and Durable: At 10 lbs, it offers easy installation without compromising on robustness.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 4100-5125 delivers the reliability and precision required for powering and supervising notification circuits in Simplex fire alarm systems.\u003c\/p\u003e","brand":"Simplex","offers":[{"title":"Default Title","offer_id":49105198842112,"sku":"4100-5125","price":2269.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/s-l1200_6d95ab6e-900b-45cd-9ea7-006db782e884.png?v=1785542383","url":"https:\/\/alotechparts.com\/products\/4100-5125-simplex-remote-power-supply-with-3-nacs-120-vac-input","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
