Designed as a high-performance central hub, the CS-20 handles heavy data workloads seamlessly with its 1.2 GHz single-core processor, 4 GB of flash memory, and 256 MB of RAM. It delivers robust, multi-format RFID support via OSDP V2-compliant RS-485 and Wiegand communication interfaces. Fully integrated with the BioStar 2 platform, it provides stable and secure centralized management. This controller is engineered to reduce wiring complexity and installation costs while maintaining high security, scalability, and physical fail-safes for businesses ranging from mid-sized facilities to large-scale enterprises.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThe Suprema CS-20 isolates critical access validation rules, event logging logs, and multi-lock relay controls away from physical entryways to prevent hardware bridging attacks.\u003c\/li\u003e\n\u003cli\u003eBuilt to store and process up to 500,000 unique card or PIN credentials alongside an extensive 5,000,000 internal text event log repository for high-traffic environments.\u003c\/li\u003e\n\u003cli\u003eFeatures three dedicated Open Supervised Device Protocol (OSDP V2) compliant RS-485 ports and two legacy Wiegand channels to manage up to four RFID readers concurrently.\u003c\/li\u003e\n\u003cli\u003eOutfitted with six configurable supervised input circuits alongside three auxiliary inputs explicitly pre-mapped for rapid fire alarm link, casing tamper monitoring, and AC power drop detection.\u003c\/li\u003e\n\u003cli\u003ePacked with four heavy-duty onboard relays alongside six digital inputs and outputs to deliver integrated power handling and control lines directly to automated magnetic lock plates and status indicators.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecification\u003c\/h3\u003e\u003cp\u003eCoreStation 20 2-Door Access Controller\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eManufacturer part code:\u003c\/strong\u003e CS-20\u003c\/p\u003e","brand":"Suprema","offers":[{"title":"Default Title","offer_id":63786193092938,"sku":"SUPM-CS-20","price":569.93,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/6896\/1354\/files\/SUPM-CS-20_01.jpg?v=1791039598","url":"https:\/\/crystaltechgroup.myshopify.com\/products\/supm-cs-20","provider":"Crystal Tech","version":"1.0","type":"link"}
