{"product_id":"aperta-fail-secure-flush-strike-lock-12vdc","title":"Aperta Fail Secure Flush Strike Lock - 12VDC","description":"\u003ch5\u003eDescription\u003c\/h5\u003e\n\u003cp\u003eThe Aperta A1SL is a fail secure flush strike lock designed for access control systems on timber, metal and UPVC door frames. The unit sits flush with the door frame surface via a 190mm x 52mm stainless steel faceplate, housing a solenoid-driven latch mechanism that engages when power is applied and releases when power is cut. In fail secure mode, the lock defaults to the locked position during power loss, keeping the door secure until power is restored.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial and residential access control installations where security during power outages is a priority, the A1SL pairs with magnetic card readers, keypads, intercoms and remote-release systems. The flush mount profile minimises projection from the frame, reducing the risk of tampering or forced removal compared to surface-mounted strikes. Installation requires a recessed cutout in the frame edge to house the mechanism behind the faceplate.\u003c\/p\u003e\n\u003cp\u003eThe stainless steel faceplate resists corrosion in coastal or high-humidity environments and maintains a clean appearance in high-traffic doorways. The strike operates on 12VDC, drawing minimal current during holding and higher momentary current during the latch release cycle. The 0.3kg weight and compact 190mm x 52mm x 40mm form factor allow the strike to be fitted into standard timber door frames without requiring significant structural reinforcement.\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\u003e0.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e190\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e52\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e40\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e400\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e290\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e230\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_A1SL_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_A1SL.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 secure mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFail secure means the lock defaults to the locked position when power is lost. The door remains secure during a power cut and cannot be opened without power being restored or manual override using a key. This contrasts with fail safe locks, which unlock automatically during power loss for fire safety compliance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat voltage does it require?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Aperta A1SL operates on 12VDC. It can be powered from a mains-fed 12V power supply or from a battery backup system in installations requiring uninterrupted operation during mains power outages.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat frame types is it compatible with?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe flush strike fits timber, metal and UPVC door frames. Installation requires cutting a recessed pocket into the frame edge to house the mechanism behind the faceplate, so the frame must have sufficient depth and material to support the cutout without weakening the structure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it be paired with a keypad or card reader?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The strike is designed to integrate with standard access control systems including magnetic card readers, proximity fob readers, keypads, intercoms and remote-release buttons. The control system sends a 12VDC signal to the strike to release the latch when access is granted.\u003c\/p\u003e","brand":"ESP","offers":[{"title":"Default Title","offer_id":45294105133323,"sku":"A1SL","price":21.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/A1SL_3ca7acea-c53f-4091-8af6-23fbbdc361a0.jpg?v=1714668159","url":"https:\/\/niori.co.uk\/products\/aperta-fail-secure-flush-strike-lock-12vdc","provider":"Niori","version":"1.0","type":"link"}
