{"product_id":"hikvision-ds-k4h250d","title":"Hikvision DS-K4H250D Double-Door Magnetic Lock 300kg per Door","description":"\u003cp\u003eThe Hikvision DS-K4H250D is a Pro Series double-door electromagnetic lock: one 480 mm body carrying two independent electromagnets, each rated at 300 kg of static linear thrust, with two armature plates for the two leaves. It is the correct answer for a double-leaf entrance — a main office doorway, a hotel or hospital corridor, a compound facility — where a single-door lock would only ever hold one half of the opening. Both leaves release together the instant power is interrupted, which is what a fire officer expects to see. Order the DS-K4H250D today from Speed4Trading with genuine Hikvision stock, official warranty and fast delivery across Egypt.\u003c\/p\u003e\n\u003ch2\u003eWhy Buy the Hikvision DS-K4H250D?\u003c\/h2\u003e\n\u003cp\u003eDouble doors are where access control projects quietly go wrong. Fitting two single-door locks means two bodies, two cable runs and two chances of mismatched release timing; leaving the second leaf bolted shut annoys everyone the first time something wide needs to come through. The DS-K4H250D puts both magnets in one surface-mounted body with one cable, so the pair of leaves lock and release as a single door. With 300 kg of hold on each leaf, 600 kg across the opening, and a dry-contact output that reports the real state back to the controller, it gives a wide entrance the same integrity as a single door.\u003c\/p\u003e\n\u003ch3\u003eKey Features \u0026amp; Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwo electromagnets in one 480 mm body — a single lock, a single cable run and a single release for a double-leaf door.\u003c\/li\u003e\n\u003cli\u003e300 kg of static linear thrust on each leaf, 600 kg across the whole opening.\u003c\/li\u003e\n\u003cli\u003eBoth leaves release together when power is cut, so an emergency release or fire alarm interface frees the full width of the doorway.\u003c\/li\u003e\n\u003cli\u003eNo latches or moving parts in the door path, so nothing jams on a doorway that sees constant traffic.\u003c\/li\u003e\n\u003cli\u003eSelectable 12 VDC or 24 VDC operation to suit the access control supply already installed.\u003c\/li\u003e\n\u003cli\u003eDry-contact output rated to 3 A gives your controller a genuine lock status for door-forced and held-open alarms.\u003c\/li\u003e\n\u003cli\u003eGreen LED for locked and red for unlocked, so commissioning and fault-finding take minutes.\u003c\/li\u003e\n\u003cli\u003eAluminium alloy shell with zinc-electroplated body and armature plates for durability in humid conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLock type: double-door electromagnetic (magnetic) lock, Pro Series\u003c\/li\u003e\n\u003cli\u003eHolding force: 300 kg per door; 600 kg total static linear thrust\u003c\/li\u003e\n\u003cli\u003eInput voltage: 12 VDC (default) or 24 VDC, selectable\u003c\/li\u003e\n\u003cli\u003eCurrent draw: 500 mA per lock at 12 VDC (2 locks); 250 mA per lock at 24 VDC\u003c\/li\u003e\n\u003cli\u003eLock body dimensions: 480 × 49 × 25.5 mm\u003c\/li\u003e\n\u003cli\u003eArmature plate dimensions: 180 × 38 × 11 mm\u003c\/li\u003e\n\u003cli\u003eShell material: aluminium alloy\u003c\/li\u003e\n\u003cli\u003eLock body and armature plate: zinc, electroplated\u003c\/li\u003e\n\u003cli\u003eSignal output: dry contact (NO \/ NC \/ COM) rated to 3 A — NO closed while locked, NC closed while unlocked\u003c\/li\u003e\n\u003cli\u003eStatus indication: green LED locked, red LED unlocked\u003c\/li\u003e\n\u003cli\u003eOperating temperature: -10 °C to +55 °C\u003c\/li\u003e\n\u003cli\u003eOperating humidity: 0 to 95%\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePerfect For\u003c\/h3\u003e\n\u003cp\u003eDouble-leaf main entrances to offices and company headquarters, hospital and clinic corridors, hotel service and banquet doors, school and university corridor doors, factory and warehouse internal double doors, compound clubhouse and gym entrances, and showroom or retail doorways wide enough that both leaves are regularly used.\u003c\/p\u003e\n\u003ch3\u003eEasy Installation \u0026amp; Compatibility\u003c\/h3\u003e\n\u003cp\u003eThe 480 mm lock body is surface mounted to the frame across the head of the double doorway, with one armature plate fixed to each leaf, so no cutting into the doors is needed and an existing opening can be converted in a single visit. L and Z brackets are available for glass or inward-opening leaves. Electrically it is one load: feed it 12 or 24 VDC from your access control power supply and switch it from the lock output of a Hikvision reader such as the DS-K1T8003MF, DS-K1T8005MFWX-B or DS-K1T807MBFWX-QRE1. Size the supply for 1 A total at 12 V, since both magnets draw 500 mA each. Run the dry-contact output back to the controller's door contact input, and interrupt the lock feed with the fire alarm relay so both leaves release in an emergency.\u003c\/p\u003e\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDS-K4H250D double-door magnetic lock body\u003c\/li\u003e\n\u003cli\u003e2 × armature plates with rubber washers and fixings\u003c\/li\u003e\n\u003cli\u003eMounting screw and bolt pack, with Allen key\u003c\/li\u003e\n\u003cli\u003eInstallation guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBuy with Confidence from Speed4Trading in Egypt\u003c\/h3\u003e\n\u003cp\u003eDouble doors are the detail most quotations get wrong, so talk to Speed4Trading before you order.
