Hing safety electronic keypad lock

Shang cheng electronic door lockThe introduce of IC chip1 CPU use the technical dedicated integrated circuit of American ATMEL Company 2 chip card reader use ST Company 324 Professional chip. Some factories use triode instead. 3 power use Tai wan HT Company's 3.3V Regulator chip. And some factories without 4 Motor drive use Tai wan BA6208 chip. Some factories use triode instead. 5 Storage chip use ATMEL Company's chip. 6 Time chip use MAX Company's 1302 time chip. 7 We use Japan KDS Company's technical crystal. 8 The motor in the door lock we use technical motor of high performance. You can change a new motor for free within two years when the motor with some problems occurs. From the above we can see that our company's circuit board has five import manifold blocks. The major manifold block even use American ATME technical chip. Compare with those factories which just have one or two manifold block. Our products have more functions. More stable. Have stronger Anti-jamming capability and more save electricity. The most important is that in order to make sure the manifold block chip is Genuine Original .we can write this list as the contract attachment to protect consumers' benefit. electronic keypad lock The introduction: 1 Stainless steel touch-tone phones switch 2 blue and green to crystal keypad 3 the second generation of ID cards can setting to open card 4 personalization induction card, easy to carry 5 you can set 300 group induction card and 10 group password 6 Europe standard anti-theft lock body 7 brass technology, decade can't be fade 8 the function of machine key to emergency open the door and reverse locked of indoor 9 the structure of combination type gear instead of tradition steel wire, it's more steady 10 this is applicable to home anti-theft door, apartment anti-theft door, office, school and so on Specification: Item Specification Static Power Consume <18uA Dynamic Power Consume <200mA The Alarming Volta <4.8v, 200 times unlocking permitted.
