When we usually buy locks, we must not look at the design of the key handle. The most important thing is the design of the key itself!
Class A lock
At present, the A-level anti-theft lock key on the market mainly has a word key and a cross key. The internal structure of the A-class lock cylinder is very simple, limited to the change of the marble, and the marble groove is small and shallow. The anti-technical opening time is extremely high within 1 minute. The marble structure is a single row of marbles or a cross lock.
Class B lock
The B-class lock key is a flat-panel key with a double-row marble slot. The difference with the A-class lock is that there is a row of curved and irregular lines on the key surface. The main types of lock cylinders are 3 types, computer double-row lock core, double-row crescent lock core, double-sided vane lock core. The anti-technical opening time is 5 minutes, and the mutual opening rate is high. With a strong twist tool, the lock cylinder can be opened in 1 minute.
Lock God Super C lock
The shape of the key is the front and back blade structure key slot, and the lock core type is a double-sided column lock core; it can not be opened by the Ministry of Public Security for 800 minutes, and the regional mutual opening rate is zero (one hundred billionth). The blade structure is 48 blades and double-sided column locking; if the lock cylinder is opened with a strong twisting tool, the inner core of the lock cylinder is broken and self-explosively locked, resulting in failure to open.
Teach you how to pick the lock:
Buy a lock to see the "teeth" of the key. The more teeth, the deeper the teeth, the more complicated the arrangement, the more difficult it is to open, and the better the anti-theft performance.
The RCU is connecting to the server center by TCP/IP and Ethernet protocol, each RCU could is connected to the hotel LAN and has an independent and unique IP address that is compatible with the Ethernet standard.
On the high voltage, there are replay outputs for the electrical equipment, the relays act as the switch and are controlled by the communication board that could receive the instruction from the 12V switches installed in the guest room.
The communication board is the core as the whole RCU like computer`s CPU, it mainly has two functions as below:
Receiving instruction signals from the switches, door plate, and sending signal to the 220V high voltage to turn on/off the lighting fixtures or control the air-conditione
The function of smart RCU as below:With strong stability;Good compatibility; Enhance the quality of hotel services ;Low cost,easy maintenance.
