It mounts directly to the door track and detects door position through a series of three magnetic gap switches, providing reliable open and closed status signals to access control panels, alarm systems, or building automation equipment. Licensed alarm system installers and access control technicians are the primary trade professionals who spec and install this device. It is sold as a complete set, meaning all switch components needed for the three-gap configuration are included in one unit of measure.\u003c\/p\u003e\n\u003cp\u003eThe 4700A is intended for overhead door installations where single-point contact coverage is insufficient and multiple position zones along the door travel path must be monitored. Typical applications include commercial roll-up doors, sectional overhead doors in warehouse and loading dock environments, and secured access points where door position must be verified at more than one stage of travel. The three-gap design allows installers to detect fully open, fully closed, and intermediate door positions from a single track-mounted assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-gap configuration monitors multiple door positions along the travel path\u003c\/li\u003e\n  \u003cli\u003eTrack mount design integrates directly with standard overhead door track hardware\u003c\/li\u003e\n  \u003cli\u003eComplete switch set sold as one assembly — all components included per unit\u003c\/li\u003e\n  \u003cli\u003eSuited for access control, intrusion alarm, and building automation signal inputs\u003c\/li\u003e\n  \u003cli\u003eOverhead door contact category rating for commercial and industrial door applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation switch set for overhead door contact applications requiring a three-gap track-mounted configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of overhead door contact switch sets is typically performed by licensed alarm system technicians or access control installers. De-energize all associated control panels and disconnect power to any connected alarm or automation equipment before beginning wiring work. Mounting hardware and wiring should comply with applicable local codes and NEC low-voltage wiring requirements. Do not force-fit the track mount bracket — verify track profile compatibility before securing the assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: 3 Gap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Track Mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Overhead Door Contacts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1 set\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: George Risk Industries Inc.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4700A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GEORGE RISK INDUSTRIES INC.","offers":[{"title":"Default Title","offer_id":51688880898354,"sku":"4700A","price":153.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6adda6826232aaa44b990e76879ddeab_90348035-dcb3-443f-8919-39a2cf66585a.jpg?v=1788252260","url":"https:\/\/voomisupply.com\/products\/george-risk-industries-4700a-3-gap-track-mount-switch-set","provider":"Voomi Supply","version":"1.0","type":"link"}
