R1-B-2.2K is a 2.2K ohm resistor used in security and alarm system wiring applications. Resistors of this type are installed in series or end-of-line configurations to supervise circuit continuity and enable zone detection by a control panel. Licensed alarm installers and low-voltage security technicians are the primary trades working with this component. It is a small, passive electrical component that regulates current flow within a supervised loop circuit.\u003c\/p\u003e\u003cp\u003eThis resistor is commonly used in hardwired security alarm systems where end-of-line (EOL) resistor supervision is required. It is suited for residential and light commercial installations where a control panel monitors door contacts, window contacts, motion detectors, or other hardwired zone devices. The 2.2K ohm value is a standard resistance used by a number of control panel manufacturers for supervised zone wiring.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.2K ohm resistance value for supervised alarm circuit wiring\u003c\/li\u003e\n\u003cli\u003eCompatible with end-of-line resistor supervision configurations\u003c\/li\u003e\n\u003cli\u003eCompact form factor for easy integration into contact housings or junction boxes\u003c\/li\u003e\n\u003cli\u003eSold individually per unit of measure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in hardwired security alarm and access control systems requiring end-of-line resistor supervision.

De-energize the alarm circuit and disarm the control panel before adding or replacing resistors in a supervised zone. Resistors are typically installed at the last device in a zone loop, inside the device housing or at the terminal block. Confirm the required EOL resistance value matches the panel zone programming before commissioning the circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance\u003c\/strong\u003e: 2.2K ohm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Miscellaneous Contacts\u003c\/li\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GEORGE RISK INDUSTRIES INC.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R1-B-2.2K\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GEORGE RISK INDUSTRIES INC.","offers":[{"title":"Default Title","offer_id":51987354878258,"sku":"R1-B-2.2K","price":17.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3da5818ae2cae907828a24fc0fd6200.jpg?v=1789986797","url":"https:\/\/voomisupply.com\/products\/george-risk-industries-r1-b-2-2k-2-2k-ohm-resistor","provider":"Voomi Supply","version":"1.0","type":"link"}
