Built for use on commercial and steel door installations, this contact provides reliable magnetic detection at the door frame without requiring flush mounting or cutouts. Licensed alarm installers and low-voltage technicians are the primary trade installing this device as part of intrusion detection or access control systems.\u003c\/p\u003e\u003cp\u003eThis contact is suited for commercial facilities where surface mounting is preferred or required by door construction. It performs well on steel doors, which are common in commercial entry points, stairwells, storage areas, and server rooms. The open-loop wiring configuration makes it straightforward to integrate into standard alarm control panel zones.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCommercial-grade surface mount design requires no door cutout or flush installation\u003c\/li\u003e\n\u003cli\u003eCompatible with steel door applications where embedded contacts are not practical\u003c\/li\u003e\n\u003cli\u003eOpen-loop circuit configuration for standard alarm zone wiring\u003c\/li\u003e\n\u003cli\u003eWhite finish for clean appearance on light-colored door frames\u003c\/li\u003e\n\u003cli\u003eLow-profile form factor suitable for commercial door hardware environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style surface mount contact for commercial door alarm and access control systems, particularly suited for steel door applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed low-voltage alarm technicians following local codes and NEC low-voltage wiring requirements. Power down the alarm control panel zone before connecting wiring to avoid false triggers or panel faults. Mount the contact body to the door frame and the magnet to the door leaf, ensuring proper gap alignment per the manufacturer specification. Do not install on ferrous metal surfaces that may interfere with the magnetic field unless the product is specifically rated for steel door use, which this unit is.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Surface Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Commercial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoor Type\u003c\/strong\u003e: Steel Door Compatible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Type\u003c\/strong\u003e: Open Loop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TANE ALARM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: sm-21wg-wh\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TANE ALARM","offers":[{"title":"Default Title","offer_id":51524847927602,"sku":"SM-21WG-WH","price":18.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35a4495d7ad80859a004821c4c3edcd7_0205cb6c-982e-4d83-b01c-3e3f40f1c971.jpg?v=1785459508","url":"https:\/\/voomisupply.com\/products\/tane-alarm-sm-21wg-wh-surface-mount-contact-white","provider":"Voomi Supply","version":"1.0","type":"link"}
