Applications: hotel,home,house, office,apartment commercial and residential door lock usage.



The basic performance parameters of door locks:


  • Working voltage: DC 6V (4 AA batteries)
  • Static current: <15 microampere
  • Dynamic current: 110-150mA
  • Battery life: normal continuous open 15000 times or about a year
  • Low power tip: when the voltage is lower than 4.8V, the red light on after you put into the card, and can still be unlocked about 50 times(will be affected by the consistency of battery).
  • Emergency open: Without any control, even the tongue locked, also can be opened.
  • Reliable performance: Continuous normal induction within 1000 times there won’t be a mistake.
  • Unlock records: According to the request of customer, can set the lock “ EEPROM” to save the latest 1000 open station records, including all kinds of cards and mechanical key to open the lock while there are records.
  • Mechanical key: With transmission completely independent mechanical emergency unlocking mechanism, high security mechanical key to ensure that emergency situations door still open normally.
  • Installation dimensions: the thickness of the door should between 38-60mm according to the door installation.

  3. Handle structure: Free handle, as opposed to static handle, can effectively prevent violent destruction. At the same time, with double springs, durable.
  4. Surface treatment: The adoption of pure stainless steel, locking plates never leg color, relative to use zinc alloy electroplating of the lock plate, it’s more upscale.
  5. Reliable performance: The T5557 card or Mifare1 card module, coil sealed in the card, not easily influenced by outside, longer life; no mechanical contact between RF card and the reader, avoid all kinds of troubles which are due to exposure to read and write. Adopt imported motor electronic micro switch and other accessories, stable and reliable performance.
  6. Easy to use: micro-wave induction, just in front of the sensor in the door zone induction, door lock can be opened.



Introduction of the Lock core


  • American Standard: The cylinder of ZYG series intelligent lock, with standard 5 tongue cylinder design, the internal structure reinforced, 20 several parts so that the cylinder internal structure is simple and durable.
  • Free motor design patent: Patented free motor design, durable, dual gear change also drive to ensure the durability of the lock body.
  • Excellent feel: Parts and accessories of each cylinder friction coefficient has been calculated to the most accurate, at the same considering in the design of the spring elastic coefficient moving parts to ensure that the lock cylinder in the switch handle, turn the handle when locked carry hand to achieve the perfect.
  • Surface treatment: Cylinder used in Japan electrophoresis paint of color zinc plating treatment, anti-corrosion and rust prevention.



The Introduction of Circuit module:


  • Customers may choose T5557 card module or Mifare1 card module according to need.
  • T5557 card module: T5557 card chip circuit adopts the Atmel company encryption card, tuning frequency 125kHz, can be encrypted, the data capacity of 330, 64 bit ID number, a wake-up response functions, read and write performance is stable and reliable quality, global uniqueness, high security performance. Easy to operate, just induct in front of the door sensor area, door will be opened.
  • Mifare1 card module: With the Netherlands PHILIPS company Mifare1 encryption card, based on the 13.56MHz frequency range reader module, it is consistent with ISO14443 standards, using untra-small,large scale integrated circuit package, the only one of global, high security and performance. Card for 16 partitions, each has a separate password, you can expand one card solution, each partition achieve independent functions, which uses a card that can actually be more than one card features, such as room door, parking, consumption, attendance, etc.
