Determining a normal mounting angle specification <br> <br> mounting height is not random, it will affect the results of the sensitivity of the detector and according to the anti-pokemons. Imagine a detector mounted at a height of 2M and a height of 2.5. When the moving object moves from the ground, the frequency of cutting the bright area and the dark area is different.
Should not face glass doors and windows
Passive infrared detectors are facing glass doors and windows, there will be two problems: First, white light interference, apparently PIR has a strong suppression of white light, but after all, is not 100% inhibition. So avoid facing the glass doors and windows, you can avoid strong light interference. The second is to avoid complex environmental disturbances outside doors and windows, such as crowd movements and vehicles.
Should not be directly on the hot and cold vents or cold and heat sources <br> Hot and cold vents and cold and hot sources may cause false alarms. For some low-performance detectors, air convection through windows and doors sometimes causes false alarms.
Not suitable for swinging objects
Easy-to-sweep objects will make microwave detectors work and therefore may also cause false alarms. The ancient attention to the purpose of installing detectors on the illegal invasion route was sufficient to prevent the criminals from making illegal intrusions. Before determining the installation location, it was necessary to consider the main population of buildings. In fact, we have prevented entrances and exits and intercepted illegal intrusions. This has achieved our goal.
Alloy steel refers to steel with high strength and good chemical stability at high temperature. It includes two types of anti oxidation steel (or high temperature resistant steel) and hot steel. Anti oxidation steel generally requires good chemical stability, but the capability is limited. High temperature strength and the corresponding oxidation resistance of heat and strong steel are required. Heat-Resistance Steel is often used in the manufacture of boiler, steam turbine, power machinery, industrial furnace and aviation, petrochemical and other industrial sectors in the work of the high temperature parts. In addition to the requirements of high temperature strength and high temperature oxidation corrosion, sufficient toughness, good shaping and welding are also required according to the different use, as well as a certain organizational stability. In addition, some new low chromium nickel oxidation are also developed .
