Magnetic door holders work by energizing an electromagnet that grips a wall- or floor-mounted armature plate, keeping the door in an open position until the magnet is de-energized. When a fire alarm or access control signal is triggered, the magnet releases and allows the door to close under its own closer force. This type of device is commonly installed by commercial door hardware technicians, electrical contractors, and low-voltage integrators as part of a life safety or access control system.\u003c\/p\u003e\n\u003cp\u003eThe EH301224A is suited for use in corridors, stairwells, and common areas where doors must remain open during normal operations but must close automatically during an alarm event. Typical installations include hospitals, schools, office buildings, and multi-tenant residential facilities. The device integrates with fire alarm control panels and building automation systems that send a signal to release the door upon detection of smoke or fire conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eElectromagnetic hold-open mechanism releases automatically on alarm signal\u003c\/li\u003e\n  \u003cli\u003eDesigned for both fire-rated and standard door applications\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit for individual door installations\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard door closer hardware for automatic close-on-release operation\u003c\/li\u003e\n  \u003cli\u003eSupports integration with fire alarm control panels and low-voltage control systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation magnetic door holder for commercial door closer and holder systems requiring electromagnetic hold-open functionality.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed low-voltage technician or commercial door hardware installer familiar with local fire code and NFPA 80 requirements for fire door assemblies. Disconnect power to the control circuit before wiring the holder to the alarm system. Verify that the door closer is properly adjusted to ensure the door closes and latches fully when the magnet releases. Consult the authority having jurisdiction regarding inspection and testing requirements after installation.\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\u003eCategory\u003c\/strong\u003e: Door Closers \/ Holders \/ Alarms\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: SDC - SECURITY DOOR CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EH301224A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SDC","offers":[{"title":"Default Title","offer_id":51686732005682,"sku":"EH301224A","price":281.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/217025ab3e9f5f0adc0205eb7ce5273d.jpg?v=1788228437","url":"https:\/\/voomisupply.com\/products\/sdc-eh301224a-magnetic-door-holder","provider":"Voomi Supply","version":"1.0","type":"link"}
