The lock operates on either 12V or 24V DC supply and uses fail-safe logic, meaning the lock releases when power is cut, allowing emergency exit during fire alarm activation or power outage.\u003c\/p\u003e\n\u003cp\u003eInstalled at the top of the door frame, the lock consists of an electromagnet plate mounted to the frame and a steel armature plate mounted to the door leaf. When powered, the electromagnet holds the armature with 250kg of force, sufficient to secure lightweight to medium-weight internal doors in residential, office, and light commercial access control applications. The lock includes both Z-bracket and L-bracket mounting hardware, accommodating different door and frame configurations including inward-opening, outward-opening, and doors with narrow frame reveals.\u003c\/p\u003e\n\u003cp\u003eThe unit measures 276mm long by 67mm wide by 75mm deep and weighs 2.4kg. An integrated LED on the electromagnet housing indicates lock status—lit when energised and holding, extinguished when de-energised. A built-in contact sensor monitors whether the door is fully closed and the armature plate has mated correctly with the magnet, providing feedback to the access control system. The lock is designed for internal use only and is not weatherproofed for outdoor or high-moisture environments.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e2.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e2.6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e13\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e276\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e67\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e75\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e360\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e285\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e900\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_A1ML250_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_A1ML250.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does fail-safe mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFail-safe means the lock releases when power is cut. This allows the door to open during fire alarm activation or power outage, meeting building safety regulations for emergency egress. The alternative, fail-secure, would keep the door locked when unpowered.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat voltage does it operate on?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe lock supports both 12V DC and 24V DC supply voltage. Most installers use 12V for compatibility with standard access control power supplies, but the lock will operate correctly on either voltage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the Z and L brackets for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Z-bracket and L-bracket provide different mounting angles to accommodate different door and frame configurations. The Z-bracket suits doors that sit flush or nearly flush with the frame, while the L-bracket suits doors that open past 90 degrees or have narrow frame reveals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it be used outdoors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The Aperta A1ML250 is designed for internal use only and is not weatherproofed.
