Operating at 24 volts DC, this body-only unit accepts a 3\/4-inch keeper and holds the door locked when power is removed - the defining behavior of a fail-secure configuration. The integrated latchbolt locking cam monitor (LCBMA) includes an auxiliary switch that reports latchbolt position back to the access control panel, giving installers a real-time door-status signal without a separate sensor. Licensed electricians and access control technicians are the primary installers of this device.\u003c\/p\u003e\n\u003cp\u003eThis electric strike is suited for heavy-use commercial doors such as stairwell entries, utility corridors, loading dock access points, and perimeter doors where a fail-secure posture is required by security protocol. The body-only configuration means it ships without the faceplate or strike box, making it appropriate for retrofit installations where the existing hardware will be reused or where a custom faceplate is already on-site. The auxiliary switch output integrates with most access control panels that accept a dry-contact door position or latch monitor input.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003eFail-secure operation: door remains locked on power loss\u003c\/li\u003e\n \u003cli\u003e24-volt DC operating voltage for compatibility with standard access control power supplies\u003c\/li\u003e\n \u003cli\u003e3\/4-inch keeper size for proper latchbolt engagement\u003c\/li\u003e\n \u003cli\u003eLatchbolt locking cam monitor (LCBMA) provides real-time latch position feedback\u003c\/li\u003e\n \u003cli\u003eAuxiliary switch output integrates with access control panels for door-status monitoring\u003c\/li\u003e\n \u003cli\u003eIndustrial-grade construction rated for high-cycle commercial and industrial use\u003c\/li\u003e\n \u003cli\u003eBody-only format supports retrofit and custom faceplate installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation electric strike for commercial access control systems requiring a fail-secure 24-volt DC unit with a 3\/4-inch keeper and integrated latch monitor output.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician or certified access control technician in accordance with NFPA 70 (NEC) and applicable local codes. Disconnect and lock out all power to the access control circuit before wiring the strike or auxiliary switch leads. Verify the door frame mortise dimensions and keeper alignment before securing the strike body to avoid binding on latchbolt engagement. Confirm that the access control panel supports a dry-contact auxiliary input before connecting the monitor switch output.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eOperating Voltage\u003c\/strong\u003e: 24 volts DC\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFail Mode\u003c\/strong\u003e: Fail Secure\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eKeeper Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eMonitor Type\u003c\/strong\u003e: Latchbolt Locking Cam Monitor with Auxiliary Switch (LCBMA)\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Body Only\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Industrial\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: HES\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 310-1 (3\/4) 24D LCBMA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HES","offers":[{"title":"Default Title","offer_id":68296029503794,"sku":"310-1 (3\/4) 24D LCBMA","price":694.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37e14e5d99868dc1cc86b733b4df4041_147740e3-e0e3-4407-9d3c-f7a94ec2fcae.jpg?v=1793698625","url":"https:\/\/voomisupply.com\/products\/hes-310-1-3-4-24d-lcbma-electric-strike-24vdc-fail-secure","provider":"Voomi Supply","version":"1.0","type":"link"}
