红外对射探测器的安装方式（Installation mode of infrared counter detector）

红外对射探测器的安装方式（Installation mode of infrared counter detector） 红外对射探测器的安装方式(Installation mode of infrared counter detector) Installation mode of infrared counter detector Pillar type installation: the more popular pillars are round and square two. The early popular is the circular section pillar, now the situation is just the reverse. The square pillar is more and more popular in the engineering field. The main detector is mounted on a square post, free of rotation and movement. In addition, there are a wide range of stainless steel, alloy, aluminum alloy profiles to choose from, is also one of its advantages. Another method of work is to use angle steel as a pillar, if you can not guarantee the line, effectively wear the pipe hidden, so that the line exposed in the air, this method can not be taken. The pillar can be in the shape of "1" shape, "Z" - shaped or curved, the characteristics and requirements of the buildings and security, the key point is that the fixed pillar should be firm and solid, no displacement or shaking, in order to facilitate the installation and design, reduce false positives. ; The wall mounted: now anti-theft market in active infrared detector manufacturer of cutting-edge technology, can provide a level of 180 degrees angle, infrared detector pitch above 20 degree angle, such as ALEPH, ABT, HA active infrared detector ABF series of products, can support the probe directly mounted on the building outer wall or fence, fence. General principles for installation of infrared emitter detectors The detector set on the channel, whose main function is to prevent the illegal passage of the human, in order to prevent pets, small animals and other false positives, the location of the probe should generally be more than 50 M above the ground. Shading time should be adjusted to a faster position, a rapid response to illegal intrusions. The detector installed on the fence, its main function is to prevent artificial malicious climb, the top installation and side installation of two can. The detector mounted on the top shall be positioned above the fence and 25 M at the top of the fence to reduce the false positives caused by small birds and kittens moving on the wall. The false alarm ability of the four beam detector is stronger than that of the dual beam, and the dual beam is stronger than that of the single beam. The side installation is the probe installed in the fence, the fence near the top of the side, generally for wall type installation, installed in the outside of the majority. This way can avoid the small birds, kitten interference. Each way has its own merits or drawbacks, and the engineering firms have their preferences for each type of installation. Users should be selected according to the characteristics of their own buildings and anti-theft requirements. Special reminder 1., the line can not be clearly deposited, it must be put into the dark tube, which is the minimum requirements for the safety of detector work. 2. the detector mounted on the wall, whose rays are furthest away from the wall, shall not be greater than 30 M, which should be paid special attention to where the wall is bent. 3. after the wiring is connected, please use the multimeter resistance file to test the power source of the probe. Engineering debugging of infrared radiation detector (a) a light axis adjusting open probe, put eyes on sight, to observe the effect of sight conditions in optical lens probe can be used directly in the hands of about 180 degrees in the range of adjustment, adjust the lens below with a screwdriver on the adjustment screw, the lens system adjustment range of 12 degree. The effect of repeated adjustment in the other sight into the central position detector. In the adjustment process, pay attention not to block the optical axis, so as not to affect the adjustment work. The light projector optical axis adjustment on the standoff sensitivity influence, please must be in accordance with the correct steps carefully adjusted repeatedly. (two) adjust the optical axis of the receiver. The first step is to adjust the optical axis of the light receiver in the same way as the optical axis adjustment of the projector. At this time, the red warning light on the receiver is extinguished, the green indicator light is long and no flicker phenomenon is indicated, the sleeve head optical axis coincides with normal, and the light projector and the light receiver function normally. The second step: there are two small holes on the light receiving device. They are labeled "+" and "-" to test the infrared intensity of the receiver, Its value is expressed by voltage, called photosensitive voltage. The universal test pen table ("+" red and black "-") is inserted into the measuring device by voltage sensitive. Adjust the lens system repeatedly so that the maximum value of the photosensitive voltage is reached. In this way, the working state of the probe is in its best shape. Note: the four beam detector has two groups of optical systems, which need to separate the upper and lower lenses of the light receiver, and adjust the value of the first and the lower photosensitive voltages. The optical system of four beam detector older two group is regulated separately, because corresponding relationship involves the transmitter and receiver two probes of four optical systems, it is very difficult to adjust, especially careful adjustment, improper handling will appear false positives or dead zone protection. The ABF four beam detector has integrated the two parts into one, so the construction is much easier. (three) the shading time adjustment in the light shading device is provided with a time adjusting knob, adjustable shading time probe in 50m/s ~ 500m/s, the probe in the factory, the factory will probe the shading time is adjusted to a standard position, under normal circumstances, this position is a relatively moderate state all, considering the characteristics of the environmental conditions and the probe itself, so there is no special reason, also without adjusting the shading time. If for fortification reasons, it is necessary to adjust the shading time to adapt to changes in the environment. Generally speaking, the time of shading is short and the sensitivity of the probe is fast, but the sensitivity to the falling leaves and the flying birds is also strong, and the possibility of false alarm is increasing. The longer the shading time, the lower sensitivity of the probe, and the possibility of missing report. The Engineer shall adjust the time of shading according to the actual need of the fortification. Link probe detectors and infrared anti-theft host set, the tamper switch access zone input circuit, the line is completed, the probe cover shell, fastening screw. In the host defense anti-theft warning lights flicker, no light, no alarm output area. The entire set of normal zones. Otherwise, check on the line, re tuning of the probe, to determine the state sector. Performance test of infrared emitter detector Stand off the normal working state, according to the fortification requirements, with all possible dimensions and prevent similar to the shape of the objects, the optical axis with different speeds and different occlusion of the probe, the alarm scene with wireless interphone is associated with the control center, inspection alarm situation is not normal, and listen closely to have no flashing alarm the host or unstable state. So as not to alarm system hidden dangers. We regard this as a verbal test fired. The purpose of the experiment is to be fired to test whether the normal alarm has the ability to stand, whether the range test can reach the predetermined area protection requirements, the existence of dead zone protection. Daily maintenance of infrared radiation detector In daily work, because of the long-term work in the outdoors, so inevitably affected by atmospheric dust, microorganism and snow and frost, fog, long before, in the outer wall of the detector tends to accumulate a layer of dust like crust in the more humid areas also grow a thick layer of moss, sometimes a bird will the excrement pulled onto the detector, these things will hinder the infrared ray transmitting and receiving, cause false alarm. Users in Japan usually entrust engineering companies to maintain, usually in a month or so dipped in detergent, clean the shell of each detector, and then dry. We have established a good credit relationship and will do our best to do it well. In addition to clean every detector shell, to do a test fired a month alarm anti-theft system performance test.
