Jointly enhance the" business philosophy, according to "leading technology. Market-based" quality management, to maintain "professional. Innovate. Focus Passion "spirit, to lead in automotive electronics. security and other aspects of electronic trends, and constantly develop new technology. New products, fully meet the needs of international and domestic customers, the motive for the majority of customer service, improve the quality of life, welcome customers to order . ? · A key to start Analysis: 1. ?????? my friend said he used a key to start the process of moving often suddenly turn off? Answer: Indeed, there are some of these products on the market, including some well-known brand products. According to our analysis, it appears now that it is mainly the following reasons: (1) Products using the relay control circuit ?????? off. ??? Many products ACC, ON, Start are used in relay. The relay is closed by a mechanical switch, off to control electricity, the automobile is inevitable because British toss and have a greater shock at high speeds, so that mechanical contacts from the moment the relay, resulting in a sudden power ON, cause the car flameout . ??? Using relay ignition can not be avoided there is a defect, the car ignition when the instantaneous current is very large, long-term work relay in this state, can cause contact burning, then damaged. (2) Bookmark and Share Product No power and memory. ??? No power memory products, when a key to start the main chip reset, the host program will return to the initial state, which is not energized standby, this car would suddenly stall. ???? We circuit controls a key to start the product of all US imported IC, without mechanical contact. ? 2. ?????? I installed a key to start later, why electric battery run out soon? Answer: The reason for this problem is a key to start the power consumption (quiescent current) is too large. ????? For a key to start, transient current generated when the ignition is large, this is normal, is also required. However, when no ignition of quiescent current must try to do the minimum, which is a basic principle of all electronic product design. Through actual testing, we found that a key to start quiescent current of some products is very large, large hard to believe, for example, the maximum quiescent current of 50mA a product, the smallest one there 30mA, installation of this product, the car battery will soon depletion it is not surprising. ? We are a key to start the product quiescent current of only 0.6mA, with the above-mentioned products close to 100 times worse. 3. Why is a key to some products ?????? start button used for some time and it broke? Answer: At present, a key to start most of the push-button, the quality and improve the Design button is an important factor to ensure the stable operation of a key to start. General Buttons are using touch switch to control the on-off, and this touch switch is life, if the poor quality of the switch, a long time the button is likely to be damaged. Our products use a key to start touch switch life of up to 200,000 times, of course, this does not guarantee no problem, so we designed a two-button switch (built two touch switches), so that even where a damage, they can also ensure the button to work properly ???? * This product is easy to install it -?? We do not recommend customers do not have to install their own experience. ???? - Way alarm installation and normal installation of this product is exactly the same, so professional installation experienced instructors, so long as the common way to install anti-theft devices will certainly install the product. Other detailed functional description: 1. Enter the security (upgrade function): When the guard lock detection line connected electric locks shut positive side, this time with the original car remote control allows locking the vehicle, then the time will be called an acoustic horn , turn lights flashing 1 next, the system is automatically entered into the security state, five seconds after the LED indicator light starts flashing. 2. Exit theft (upgrade function): When the unlock detection line connected electric lock unlocking the positive side, this time with the original car remote control allows the vehicle unlocked, then the time will be called the second acoustic horn, turn signals flashing 2 next The system automatically exit alarm status, LED light goes off. 3, manually shut function (choose to install): when the manual shut-wire input a 12V high, then the system outputs a signal shut, shut the door immediately; (12V positive trigger voltage requirements) 4, manual unlocking function (choose to install): When a 12V input manually lock line high, then the system outputs a signal to unlock the doors unlock immediately; (12V positive trigger voltage requirements) 5, a vibrator alarm: When the system is in the security state, If the first shot of the vibrator, the horn beeps five seconds flash separated, direction lights flash 5 next synchronization; if the trigger again, the horn beep continuously for 15 seconds, the direction lights flashing for 15 seconds. 6, pause the alarm: When the system is in alarm status, such as ACC alarm, foot brake alarm, side door alarm, vibrator alarm, then shut up at this time if a positive electrical signal input, the alarm stopped, but not revoke the security state. 7. Illegal alarm: When the alarm system is in ACC, foot brake alarm, side door alarm, the system beeps the horn continuously for 30 seconds, the direction of synchronous flashing 30, enter the shut detection signal is suspended, input unlock detection signal is canceled security state. 8, after the remote control to open the trunk :( optional remote control has the function, the original car remote control does not support) in the lifting of the state of security, long button for two seconds to open the trunk, the output line bit red (small wire) Output Negative signals. 9, snatches Function :( optional remote control has the function, the original car remote control does not support) in the driving state long key 3 seconds to enter into snatches state where the direction of light flashes for 30 seconds, 30 seconds La ming long after the alarm system off, only use the remote control to unlock the key to stop the alarm, another key operation is invalid. 10, central locking automation: 10 seconds in the car with the brakes, the doors automatically lock shut, to ensure road safety, when the parking stall, central locking unlock automatically. 11, off state memory: Before power-down, anti-theft system is in what state, regardless of the length of time after a power failure, the system re-eligible electricity 3 seconds, alarm system will automatically revert to the status before the power failure. 12, car door flashing Tip: the vehicle is traveling on the way, when the temporary parking guests open the door up and down, the vehicle direction immediately lights flashing for 15 seconds, to remind the rear car note. 13, automatic recovery security: when the system enters into the security state, if the time has revoked security, without opening the door, the system will automatically open theft in 30 seconds; if the door is opened, automatically restore security function fails. 14, parking security tips: When the owners flameout parking, car doors and close the door, the system will prompt the owners after 10 seconds the car into the security prompt way: fast beeps 3 horn sound, direction lights are synchronized fast flashing 3 next. 15, the door is not closed Tip: When the car into the security state, if the door is not closed, the system will prompt the owners in five seconds after the door is closed, revealing way: fast beeps 3 horn sound, direction lights are synchronized Fast flash 3 and to direct the police in 5 seconds. ???? - Technical Parameters 1.
