Different from the traditional mechanical lock smart lock, is a safety, convenience and advanced technology, complex locks. The card is equipped with sophisticated contactless IC card / TM smart card electronic locks and intelligent non-contact proximity card electronic door locks, the main chip: T5557, EM4469, EM4305, or M1 card S50, strong S70 / CPU anti-jamming capability Mifare 1 card fast anti-collision mechanism, while the multi-card reader to enter within the scope of the data can effectively prevent interference between the card, so that one of the card reader devices can be processed to improve the application of parallelism and speed of operation of the system. The T5557 card at the same time there are several cards simultaneously near the reader, may have several cards simultaneously writing data to these product advantages: 1, two-chip circuit design, automatic efficacy, double protection 2, hidden lock, standard emergency mechanical key to open the door 3, electromagnetic induction technology, sensor sensitivity, 360 degree identification card 4, automatic wake-up function of the induction, low power consumption 5, low power consumption, automatically prompts undervoltage, this time can still unlock 200 times above and with mechanical key 6, power down for 10 years without loss of data, security is guaranteed 9, multi-language translation capabilities to support independent software management 10, ANSI tamper five tongue lock heart, strict aging test smoke, strong anti-load design 11, support for software development 12 2 times, five rights management, lost card can report the loss of 13, false alarm 14 to lock the door is not closed, double composite lock structure, compressive force over design Specifications: 240 * 75,263 * 78,280 * 79,300 * 75,290 * 78,288 * 78 different specifications Material: stainless steel, copper material, zinc alloy material Other Description: Color can be customized according to the customer's preferences, the card can be used free design (You can design patterns according to customer requirements of a personality).
