1. Is it working properly when inserting a card or brushing a magnetic card?
To repeatedly insert the card or to sense whether the magnetic card is operating normally, there should be no "no response", "error" or "motor rotation" phenomenon. To investigate the information on the brand's door lock, the clock volume is not easy to confuse. As long as the performance of the smart door lock is checked, those so-called additional functions may not be effective. The door lock of the self-correction function circuit should be selected. If you choose an immature product, you may not be able to use or maintain it. Hengyi intelligent door lock circuit microcomputer chip control, the circuit comes with information error correction function, so that the circuit processing information is more stable, the sensor door lock adopts dual clock correction error rate is very low, the sensor door lock adopts wireless data collector for door lock maintenance, It is very convenient to collect open record data.
2. Select the sensor card lock first check its sensitivity and then understand the static power consumption of the sensor lock
Because the general sensor door locks are powered by dry batteries, it is very important to understand the static power consumption of the sensor door locks. At present, some brands of sensor door locks can be used continuously for more than one year. Some brands change the battery in less than a month. Frequent battery replacement will seriously affect the use. Keyu Inductive Door Locks has a leading industry-leading level of multi-line technology, with a static power consumption of 10uA, and four-section 7# dry batteries can be used continuously for more than one year. Keyu sensor door lock uses infrared sensing to identify two levels of power. The power-on mode is the most stable induction power-on mode at present. The largest brands in China adopt this power-on mode. At present, some brands use electromagnetic wave recognition. In the card power mode, the power consumption of the electromagnetic wave mode is larger, because this method uses less infrared tubes, and uses the antenna to generate weaker signals continuously (no strong signals can be generated because long-term strong signals will consume large amounts of power). card. Because of different panel materials (generally the door locks will have copper, alloy, stainless steel and other material panels, as well as gold, silver, chromium and other plating processes) will be difficult to control the weak signal to a different degree of attenuation of the circuit Transmitting power causes the current electromagnetic wave to power up in an unstable manner. The advantage of the electromagnetic wave power-up mode is that the entire black area of ​​the card can sense the power-on, but the black card of the infrared power-on mode card cannot be directly powered on ( Since pure black does not reflect infrared rays, it is recommended that infrared power-on is used for stability. Cards can not be printed with pure black on the whole surface. Inks can be printed with gray and black on the entire surface. In fact, very few customers choose the entire surface to be pure. Black is the background of the card.
3. The selection of materials to choose intelligent lock and door panel surface plating is uniform <br> <br> in the purchase, claiming the use of copper is copper panels or imitation gold-plated steel plate, stainless steel plate 304 using Stainless steel is also a 2 to 3 times cheaper common stainless iron. The user can also use PVD surface treatment. The normal use of PVD surface treatment does not fade for 15 years. If you choose ordinary plating surface depends on whether the door lock surface protection paint. Keyu Huaneng has always insisted that the products are real materials, such as the nominal pure copper panel, the handle must be pure copper, such as the nominal 304 stainless steel material must be 304 stainless steel. Pure copper forged made of imported high quality brass rods. PVD can sweep grainy light in the middle. The thickness and weight of the panel can be guaranteed. The plating layer completely meets the salt spray test standard. It is generally recommended that the user use a surface-treated PVD, sweeper chrome, stainless steel. And developed a cast stainless steel panel. After three or five years, the door lock is still bright as new.
4. Selection should understand Fingerprint Fingerprint door lock system in the selection <br> <br> lock, be appreciated that the fingerprint acquisition system is an optical fingerprint collection system, an ultrasonic system or a semiconductor fingerprint fingerprint system. The optical fingerprint acquisition system used by Keyu Huaneng is most suitable for the use of the door lock environment. Compared with other acquisition systems, the optical acquisition system has strong anti-static capability, good system stability, and long service life. It can provide high-resolution images and achieve fingerprint image acquisition in larger areas. 5. Press the handle to open the door lock is flexible, smooth <br> <br> lock body there should be serious, "Crash," "chirp" sound mechanical friction. Gently press on the handle to press the handle back to normal. Mechanical transmission can not rely on oil lubrication, depends on the mechanical connection is compact, such as relying on oil lubrication Once the oil is dry after prolonged use, the door lock fault frequently.
6 to choose whether there is a standard five-bolt structure of the lock body, the lock body inside the lock to be driven by a motor
Whether the lock body is a standard five-bolt tongue or not, whether it has a flood prevention insurance tongue, an indoor interlocking large tongue and a mechanical key to open the door. Keyu Huaneng adopts a standard five-bolt tongue and a high-performance motor to drive the locking pin. The movements of each bolt are signal-switched and recorded, and a mechanical key is used to open the door. In addition, Keyu uses a unique coil spring drive locking pin mechanism, which greatly improves the stability of the latch pin than other parallel springs.

Emergency LED drivers are designed specifically for light fixtures . These emergency backup drivers regulate the power supplied to the LED fixture the same way normal drivers do , but they operate off of a battery instead of line voltage . Because they operate off a battery the light output isn't as bright as the fixture normally would produce , but it will be just enough in an emergency situations . Most of our emergency LED drivers have a maximum emergency operation time of 120 minutes .
