M-8-B Magnetic Contact Magnet","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe GEORGE RISK INDUSTRIES INC. M-8-B is a replacement magnet designed for use with magnetic contact switches in the 28\/29 Series. Magnetic contacts are security and sensing components used to detect the open or closed state of doors, windows, or access panels in alarm, access control, and building automation systems. This unit ships as a single magnet (sold individually) and pairs with a corresponding reed switch housing to complete the contact assembly. Electricians and low-voltage alarm technicians are the primary installers of this type of component.\u003c\/p\u003e\u003cp\u003eThe M-8-B magnet is intended for installations that call for 28 Series or 29 Series magnetic contact assemblies from George Risk Industries. It is used in residential and light commercial applications where a replacement or spare magnet is needed without replacing the full contact set. Typical install locations include door frames, window frames, and cabinet panels in intrusion detection and access control systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReplacement magnet compatible with GRI 28\/29 Series magnetic contact assemblies\u003c\/li\u003e\n\u003cli\u003eSold individually for targeted replacement without swapping the full contact set\u003c\/li\u003e\n\u003cli\u003eDesigned for low-voltage door, window, and panel sensing applications\u003c\/li\u003e\n\u003cli\u003eCompact form factor suited for surface-mount contact installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with George Risk Industries 28 Series and 29 Series magnetic contact switch assemblies as a replacement magnet component.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed low-voltage or alarm technicians in accordance with local codes and NEC Article 725 for low-voltage circuits. De-energize the circuit and disarm the alarm system before servicing any contact component. Ensure the magnet is aligned properly with the reed switch housing at the manufacturer-specified gap distance to guarantee reliable actuation. Do not substitute magnets from other series, as field strength and physical dimensions may differ.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries Compatibility\u003c\/strong\u003e: 28\/29 Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each (sold individually)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Miscellaneous Contacts\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: M-8-B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GEORGE RISK INDUSTRIES INC.","offers":[{"title":"Default Title","offer_id":67988505395506,"sku":"M-8-B","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3022cc3a6c5746bd02a1a97363a446da.jpg?v=1792297826","url":"https:\/\/voomisupply.com\/products\/george-risk-industries-inc-m-8-b-magnetic-contact-magnet","provider":"Voomi Supply","version":"1.0","type":"link"}
