It provides three notification appliance circuits by default, with the option to expand to six using the 4100-5115 module. Each NAC can be configured as either Class A or Class B, giving installers flexibility for system design. Supporting both TrueAlert non-addressable devices and conventional reverse-polarity operation, the 4100-5101 ensures compatibility across a variety of notification appliances. Built to meet UL 864 standards, the unit guarantees that all circuits are power-limited, maintaining safety compliance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eExpansion Power Supply: Adds extra power capacity for 4100 series fire alarm systems.\u003c\/li\u003e\n\u003cli\u003eThree Standard NACs: Provides three notification appliance circuits, expandable to six with 4100-5115.\u003c\/li\u003e\n\u003cli\u003eFlexible Wiring Options: NACs configurable as Class A or Class B circuits.\u003c\/li\u003e\n\u003cli\u003eTrueAlert and Conventional Support: Compatible with non-addressable TrueAlert devices and reverse-polarity operation.\u003c\/li\u003e\n\u003cli\u003eIntegrated Power Distribution: Supplies both card power and signal power via the PDI.\u003c\/li\u003e\n\u003cli\u003eLocal Bay Limitation: Signal power is available only in the bay where the unit is installed.\u003c\/li\u003e\n\u003cli\u003eUL 864 Power-Limited Circuits: Ensures safety compliance across all NAC outputs.\u003c\/li\u003e\n\u003cli\u003eExpandable Design: Supports future system growth with NAC expansion module.\u003c\/li\u003e\n\u003cli\u003eReliable Construction: Engineered for long-term performance within Simplex 4100 systems.\u003c\/li\u003e\n\u003cli\u003eDurable Build: Weighs 15 lbs, suitable for robust panel configurations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 4100-5101 delivers the reliability and precision required for extending notification and power capacity in Simplex 4100 fire alarm control systems.\u003c\/p\u003e","brand":"Simplex","offers":[{"title":"Default Title","offer_id":49105203069184,"sku":"4100-5101","price":1686.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/s-l640_6653e184-3118-4783-8b98-ab45e19d1669.jpg?v=1785542475","url":"https:\/\/alotechparts.com\/products\/4100-5101-simplex-fire-alarm-expansion-power-supply-3-channel-120-vac","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
