Mobile phone burglar alarm installation and maintenance:
1. Remove the adhesive protective film at the bottom of the alarm and stick it to the table;
2. Connect the induction spring wire to the telephone line jack on the right side of the alarm;
3. Tear off the adhesive protective film on the middle box of the induction spring wire, stick the back of the digital product on the square box of the induction spring wire, and stick the small contact to the front of the digital product. At this time, the alarm sounds two consecutive times. As soon as the alarm is activated, the second alarm is automatically turned on for the alarm to enter the working state;
4. Insert the power into the MCUSB jack on the left side of the alarm. At this time, the red light is on, indicating that the alarm is already charging;
5. Plug one end of the patch cord into the digital product, and insert the other end into the MCUSB jack on the middle box of the induction spring cable to charge the digital product.
6. Note that the factory password of the alarm is 345. If the remote control is pointed at the alarm, press the 3 4 5 button to unlock it. If necessary, please change the password yourself. Please refer to the front of the package for the change method.
7. Change the password: Unplug the induction spring cable from the telephone line jack on the right side of the alarm. At this time, the alarm will alarm; press the password to cancel the alarm, then press and hold the remote control's setup button to hear the sound. After one click, enter the old one. When the password is correct, the alarm will sound for two seconds. If it is not correct, it will not ring. Then enter the new three-digit password. At this time, the alarm will sound for 2 seconds. Enter the new password again and the alarm will sound 3 times.
The new password can be used. Note that the password is 3 digits. The new password must be entered twice. If the input interval exceeds 15 seconds, the alarm will sound to indicate that the password has been changed.
8. Forgot your password: The installed alarm is removed from the desktop. Use a paper clip to insert the small round hole on the reverse side of the alarm. At this time, the green indicator flashes 3 times. The alarm is restored to the factory state. The password for the factory state is 3 4 5 ;
9. False alarm: Generally, the digital product is not installed or the induction spring wire is not connected stably. Check and replace the 3M glue or the induction spring wire to repair it;
No alarm: Generally there is no electricity or the digital product is not installed. The alarm does not enter the working state. Solution: Observe whether the green light of the alarm is flashing. If there is flashing, it means that the digital product is not glued or the induction spring wire is not inserted.
If the green light of the alarm does not flash, please charge the alarm first, and if the digital product is installed, if the problem is not solved, please follow the second operation of use and maintenance;
10. If the problem is not resolved or there are other problems, please contact the dealer;
11. If the phone is unstable when replacing the phone, please do not continue to use it.
Production process
Welding elbow production process, if the long radius of the elbow, you must first select specifications, put forward the tube material. Spread ratio, through theoretical calculation, the general expansion rate of 35% - 33%, and push back. Short radius 219mm general expanding diameter rate of 50%. Selected raw materials, in material according to the specifications of the elbow, then consider the radius of curvature, for example, 90 degree elbow, by its curvature can figure out how many materials can be processed with 90 DEG elbow. It can be calculated by theoretical calculation, and then cut off with the length of the length. Finally, the material pushing system. You may have seen the machine, the actual is very simple. It is a horn shaped mandrel or mandrel, the mandrel is changed from thin to thick, push the process is a process of expanding with bending. Behind a support pipe section to penetrate mandrel material, one behind the arch frame will be fixed mandrel.

Technological process
Seamless elbow: elbow is a kind of pipe fitting used for turning of pipe. In the pipeline system used in all the pipe fittings, the largest proportion, about 80%. In general, different forming processes are selected for different materials or wall thicknesses. At present, the factory used seamless elbow forming process, hot stamping, extrusion have.
Hot forming
Hot bend forming process is the special Elbow push processing machine, a core mold and a heating device, which makes in the mold blank in pushing mechanism driven by forward motion and in the movement is heating, expanding diameter and bending forming process. The deformation characteristics of the hot pushing elbow is based on the metal plastic deformation before and after constant volume law to determine the tube diameter, the tube diameter less than the diameter of the elbow, the through mandrel control the blank deformation process, the arc by the compression of the metal flow, compensation for expanding and other parts of the thin, in order to get uniform wall thickness of elbow.
The hot pushing elbow forming process has the advantages of beautiful appearance, uniform thickness and continuous operation, suitable for mass production. Therefore, it becomes the main processing method of carbon steel, alloy steel elbow, and is also used in some specifications of stainless steel elbow forming.
The heating method of forming process has the intermediate frequency or high-frequency induction heating (the heating coil can be multi circle or single ring), the flame heating and the reflection furnace heating.
Stamping forming
Stamping elbow is the earliest application in mass production, the forming process of seamless elbow, at present, in the production of the elbow of the commonly used specifications has been hot pushingpipe method or other forming techniques of alternative, but in some specifications of elbow due to less number of production, wall thickness too thick or too thin.
Products have special requirements are still in use. The stamping of the elbow is formed by using the tube blank equal to the outside diameter of the elbow.
Before stamping, the tube blank is placed on the lower die, and the inner core and the end mould are filled in the tube blank, and the upper die downward movement begins to press down.
Compared with the hot pushing process, stamping the appearance quality is inferior to the former; stamping elbow in the forming of arc in tension and other parts of excess metal is not the compensation, so outside the arc wall thickness reduction thin about 10%. However, due to the characteristics of the single piece production and low cost, the stamping elbow process is used for the manufacture of small batch and thick wall elbow.
Stamping elbow points cold stamping and hot stamping two kinds, usually based on the properties of materials and equipment selection of cold stamping or hot stamping.
Cold extrusion bend forming process is the use of special elbow forming machine, tube into the outer mold, mold clamping, under the push of tube billet reservation along the inner mould and the outer mould gap of movement and forming process.
The elbow made by cold extrusion technology of internal and external mold is beautiful, uniform wall thickness and small size, so it is used for stainless steel elbow, especially for stainless steel elbow. The precision of internal and external die used in this process is high, and the requirement for the wall thickness deviation of tube blank is also very strict.
