Daughter cards are modular expansion components that mount directly to a main control board, extending its communication capabilities without replacing the primary hardware. This card provides a stable, hardwired Ethernet connection as an alternative or supplement to wireless communication paths. It is typically installed by low-voltage security technicians or alarm system integrators during panel commissioning or as a field upgrade to an existing installation.\u003c\/p\u003e\n\u003cp\u003eThis daughter card is suited for residential and light commercial wireless control panel installations where a reliable wired network connection is required. It fits into panel enclosures that support modular daughter card expansion, making it a straightforward add-on during new installs or service calls where wireless-only communication is not sufficient for the application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdds wired Ethernet connectivity to compatible wireless control panels\u003c\/li\u003e\n  \u003cli\u003eModular daughter card design mounts directly to the main control board\u003c\/li\u003e\n  \u003cli\u003eSold individually as a single unit replacement or upgrade component\u003c\/li\u003e\n  \u003cli\u003eSupports stable hardwired network communication paths for control panel reporting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style expansion daughter card for compatible QOLSYS INC wireless control panels that support modular Ethernet connectivity upgrades.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed low-voltage or alarm system technician. Power down the control panel completely before seating or removing any daughter card to avoid damage to the board or connected components. Follow the panel manufacturer's documentation for proper card orientation and seating. Local codes and the National Electrical Code (NEC) low-voltage provisions may apply depending on jurisdiction.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Category\u003c\/strong\u003e: Wireless Control Panels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: QOLSYS INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: QC000B-840\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"QOLSYS","offers":[{"title":"Default Title","offer_id":51561610445106,"sku":"QC000B-840","price":105.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53871f62edfbf091fbd37bb0752ce7e8.jpg?v=1786466463","url":"https:\/\/voomisupply.com\/products\/qolsys-inc-qc000b-840-ethernet-daughter-card","provider":"Voomi Supply","version":"1.0","type":"link"}
