American standard lock core,sturdy and durable

Low voltage alarm function

 

Designed by US designer, A8 series door lock has a perfect shape. Its plate and handle are made of stainless steel, handle has independent cylinders; it can be locked inside when simply lifting up the handle. The smart sensing card, mechanical key opening method and low voltage alarm assure you a safe and reliable operation. The standard five-tongue lock of American standard and DT double-gear clutch guarantee a long life of use.

 

Design: A8 series smart door lock is a classic lock designed for five star hotels. It outperformed other smart door locks with its excellent quality, stable performance and complete function.

 

Material: The door plate of A8 series smart door lock is made of stainless steel which ensures a longer life time in public places with its hard surface.

 

Handle structure: handle with independent cylinder is adopted to prevent violent break while double springs assure you a longer use of life.

 

Surface: with pure SUS304 stainless steel, the lock plate will never fade and it looks more modern compared to those of zinc alloy plating.

 

Lock the door from inside: it allows for locking the door from inside by lifting up the handle which is convenient and modern.

 

Reliable performance: T5557 card or Mifarel card model is used; wires are sealed in the card and will not be impacted by the external environment which allows for a longer life of use. There’s no contact between Radio frequency card and reader which prevent faults. Electronic components including imported micro switch are used to assure a stable performance.

 

 Ease of use: micro sensing method is adopted. You can open the door by simply showing it in the sensing area of the door lock.

lock cylinder

American standard: A8 series smart door lock uses standard five-tongue cylinder and more than 20 components. Its reinforced structure makes it easy to use.

 

Independent motor design is patented and solid. The use of double gears assures it extended life.

 

Hand feeling: the friction among all components and elastic coefficient of the spring are precisely calculated to achieve the best feeling for your hand when turning the lock.

 

Surface: cylinder surface uses electrophoretic paint or color zinc plating and it is anti-corrosion and anti-rust

 

Circuit module:

You may choose T5557 card or Mifare 1 card module

T5557 card module: the chip and circuit of T5557 card use encrypted card of Atmel, a US company. It has a tuning frequency of 125k Hz, database of 330 bit and ID number of 64. It has a wake-up and-respond function with stable and safe reading and writing performance.

 

Mifarel card module: it uses Mifare1 encrypted card of Philips. The card reading module uses a frequency of 13.56 MHz that meet ISO14443 standard. Extra small ULSIC is adopted to ensure its safety. The card has 16 sections with independent passwords and can be extended to be used as a multi-function card for door, parking, consumption and clocking, etc.

 

Basic performance parameters of door lock:

Voltage: DC 6V (four AA batteries)

Static power loss: < 15 microampere

Power loss during work: 110 -150 milliampere

Battery life: 15000 times of normal opening or one year

Low voltage alarm: when the voltage is lower than 4.8V, the light will be red after inserting the card and the lock can be opened for another 50 times (may vary according to different battery).

Emergency opening: even the square tongue is locked, it can also be opened in emergencies

Reliable performance: no mistakes in continuous and normal operation (sensing) of 1000 times

Opening record: according to the client’s requirement, 1000 most recent opening operation can be recorded in “EEPROM”, including card and key opening records.

Mechanical key: it has an independent structure and safe mechanical key for opening in emergency.

Installation dimension: the door thickness shall fall between 38 to 60mm.
