First, prevent electromagnetic interference
For readers and door openers, special attention must be paid to electromagnetic interference, especially for lighting switches, electric typewriters and computers. If conditions permit, the reader should be installed at a distance of more than 30cm from the power source.
Second, prevent transmission signal attenuation
The installation of the access controller must take into account the distance between the controller and the reader. The ideal transmission distance is within 100m. For signal transmission cables, cable shielding and signal attenuation due to long-distance transmission must be taken into consideration. During the construction of the pipeline, the line pipe and cable tray made of steel should be used, and reliable grounding should be performed.
Third, the access controller and system software debugging
System debugging is the key to ensure the quality of the access control system. The emphasis is on the commissioning of the access controller and the operation of the system software. The commissioning of these two parts must be carried out by the manufacturer at the same time. The function of the controller is to set the relay linkage output function according to the need besides the card reader input, the time and location of the alarm generation and start-up such as camera, alarm horn and so on.
Hot melt adhesive is a kind of solid thermal decomposing material, mainly composed of quartz, silica, sodium carbonate and other substances, is an environmentally friendly hot gel. The main component of hot melt adhesive is quartz, quartz is a non-toxic mineral, the main component of quartz is silica, silica melting in a high temperature environment will release silica, which is a low-toxic substance, but if long-term contact with hot melt adhesive, it may cause certain harm to the human body.
In daily life, hot melt adhesive is mainly used to manufacture building materials, but also can be used to make cloth, paint and so on. In the process of using hot melt adhesive, wear a mask and gloves to avoid direct contact.
Pay attention to the three major points do not make access to install outsiders
Do you remember the pop star drama "You From the Stars" in previous years? I believe that in addition to the professor's boyfriend and Qian Song Yi's beauty and emotional drama that, the most intriguing is the use of keyless door locks on the two protagonists - home password and fingerprint identification access control system. This kind of seemingly high-tech, high-cost open door-to-door approach is actually not “people-friendly†as it was not imagined. The application of access control systems to the homes of ordinary people is not uncommon. On the contrary, the popularization of access control systems has become a general trend. So how do ordinary users who do not understand vulnerabilities and who do not understand the access control system to be installed in the home access control system are not pitted? Do not worry, pay attention to the following three points to help you not be a layman.
