How to check the stability of the security door?

The stability of the security door is of utmost importance. This is the primary condition for customers to purchase the security door. Unstable security doors can cause chaos alarms and missed alarms, making staff utterly indifferent, and security doors fail to play a real role. Because the sensors of the security door (that is, the two side panels of the door body) are outwardly open, it can both emit electromagnetic waves to the external environment and can also receive electromagnetic waves generated by the external environment. There are many devices that generate electromagnetic waves in the external environment, such as high-voltage lines, large motors, welding machines, mid-frequency ovens, walkie-talkies, etc., which will radiate fusion electromagnetic fields outward. These magnetic fields will interfere with and affect the normal detection of security gates; therefore, all security gates More or less will be disturbed by the external environment. Manufacturers with technical strengths can solve the stability of the security doors at the same time, they can deal with external disturbances, so that the degree of interference by security doors to a minimum.

Generally, security gates should be designed with real-time signal strength indicators, which can show the size of metal objects and the strength of interference signals. The real-time signal indicator has a very important role in the initial installation and during use. During the initial installation and during use, the security door can be adjusted to the appropriate detection parameters in accordance with the conditions indicated by the signal lights, minimizing the disturbance caused by the external environment as much as possible, thereby improving the detection accuracy of the security door. Some manufacturing companies cancel this signal to hide their eyes and eyes, or turn off when no one passes, letting the user think that the security door is working properly. As everyone knows, the security door at this time has been in an unstable state, whether or not you carry metal through it. Will alarm. The security door with signal strength indicator can be adjusted according to the interference intensity during installation, eliminate the influence of outside interference on the security door, and ensure the normal operation of the security door. Security door with environmental self-test function, effective to achieve anti-jamming, exhaust.

Choose to test in the same environment (including power supply, external environment electromagnetic interference the same situation): power on, block the infrared device, to release the infrared limit alarm function. Set the alarm sensitivity to a more sensitive (higher) level, and let the security gate wait in alarm. Observe the number of blinking signal lights. If there are many bright numbers or even a chaotic alarm, you can try to change the work of the security door. Frequency, to avoid the interference of the adjacent frequency, until the signal light is minimal. If the operating frequency is changed, the work of the security door is still unstable or even alarmed, indicating that the security door itself has poor stability and anti-interference ability. It is necessary to compare the security doors of various models one by one and choose the best one under the same detection capability (probing the same metal object).

Self-Recovery Rapid Door

High Speed self-Recovery Rapid doors are the technological evolution of old, PVC high speed doors or heavy folding doors, now obsolete and not suited to today's industrial needs.

High-quality panels, the resistive safety edge fitted to the bottom edge of the door, photocells and barriers make this product both safe and durable, being totally self-repairing, thanks to its special [Anti Crash System".

This door designed with a perimeter structure in galvanized or stainless steel, which is ideal for sliding panels. The door panel rides effortlessly within a track, thanks to the special profile and hinge designed by us, requiring low maintenance. The panel is rolled up on a roller placed within the upper crossbeam.

The door can be equipped with a counterweight or ups batteries, to fully open the door in case of power failure, and can also be equipped with large transparent sections to create a brighter and safer working environment.

Self-Repairing Door Curtain made of reinforced PVC, with flexible weighted soft bottom edge.

The edge of curtain has continuous injection molded teeth that then move up and down in a self-lubricating polyethylene track attached to structural galvanized side frames.
