---Adopting the original factory sealed Philips chips from Germany
---High integrated design with MCU, timer and memory on one board, easy to use and manage
---Advanced circuit protection, even insert other steel cannot damage its circuit and still work normally. Slanting insert card would not disturb the contact, avoiding circuit damage caused by vicious insert.
---Our PCB adopts SMT technics, has high reliability after complete aging test.
---The surface of PCB has been printed specific paint, which is anti-cauterization, anti-mildew and antistatic, has the property of low energy dissipation and long life for more than 10 years' normal use
---Working temperature: -20-50^C
---Static energy dissipation: <=3uA
---Dynamic energy dissipation: about 200mA
---Comparatively humidity: <95^C
---Antistatic: 15000V(can work stable under strong static, without losing the address)
---Power supply: 2-3 pairs 1.5V alkalescency batteries
---Battery usage period: 12-16 month
---lock adopts encrypting type Simens SLE4442 IC or Atmel Temic card or mifare card, which is highly reliable and difficult to copy because of its strong protecting function that avoiding decrypt and self-damage.
---Front of IC card: hotel name, star signal, telephone, address, hotel logo, hotel views, hotel image and so on.
---Back of IC card: Standard words or paints for teaching the customer how to open the door.
---Complete rank management and area control of the hotel, can achieve one card for several locks and one lock with several keys.
---Control the rights of opening, to achieve limiting the time of guest enter the room and avoiding guest leave without payment.
---Advanced memory function of recording opening status, can save as many as 256 pieces of recording information, easy for you to manage and search.
---High reliable emergency control system makes sure the lock can work normally under emergency by mechanical key.
---Adopt international standard 5 lock tongues, which have independent anti-dial tongue, main lock tongues and back lock tongues.
---Change the batteries after the alarm of low voltage. The lock can be opened 200 times after the alarm.
