Infrared detector installation methods and precautions

Infrared radiation detector active infrared radiation intrusion detector consists of active infrared transmitter and passive infrared receiver. When the infrared beam between transmitter and receiver is completely blocked or blocked by a given percentage, it can generate an alarm state. The device is called active infrared intrusion detector.

Installation 1 Pillar-style installation: The popular pillars are round and square, and the more popular ones are round pillars. The current situation is exactly the opposite. Square pillars are becoming more and more popular in the engineering world. The main reason is that the detector is mounted on a square pillar without rotation and is not easy to move. In addition to this, there is a wide range of stainless steel, alloy, and aluminum alloy profiles to choose from. Another type of practice is to use angle steel as a pillar. If it is not guaranteed that the track can effectively penetrate the dark deposit and the line is exposed in the air, this method is not acceptable.

The shape of the pillars can be "1" shape, "Z" shape or curved, depending on the characteristics of the building and anti-theft requirements. The key point is that the fixing of the pillars must be firm and firm without shifting or shaking to facilitate installation and Fortification, reduce false positives.

2 Wall-mounted installation: Now the leading manufacturer of active infrared detectors in the anti-theft market, can provide infrared detectors with 180° omni-directional angles and pitch angles above 20°, such as ALEPH active infrared detectors HA, ABT, ABF series products can support the direct installation of probes on the outer walls or walls or fences of buildings.

Installation Notes 1. Lines must not be applied in a definite way, and must be hidden. This is the minimum requirement for the safety of the detectors.

2. For a detector mounted on a wall, the maximum horizontal distance of the ray from the wall edge should not be greater than 30M. This requires special attention when the wall is curved in an arc.

3. After the wiring is connected, please use the resistance of the multimeter to test the power supply terminals 1 and 2 of the probe to confirm that there is no short circuit fault before turning on the power supply for debugging.

Poly aluminium chloride (PAC) is a new type high efficiency inorganic polymer coagulant, adopting advanced manufacturing technique and quality raw material, show the features of low impurity, high molecula weight, and superior coagulating effect. 

 

I. Poly Aluminium Chloride Properties


1. Its dosage lower than aluminum sulfate (based on Al2O3) and water treatment cost is lower than other inorganic flocculants. 
2. The product can cause quick formation of flocs, big flocs formation and rapid precipitation. Its treatment capacity is 1.3-3.0 times of other inorganic flocculants. 
3. It enjoys wide-range adaptability for different-temperature source water and a good solubility. 
4. It is slightly corrosive and easy for operation. 
5. The liquid product is suitable for automatic dosing. Furthermore, it will not block pipes over long-time usage.

II. Description

Product Name:

Polyaluminium Chloride (Poly Aluminum Chloirde, Polyaluminum Chloride, Poly Aluminium Chloirde, Aluminum Polychride, PAC )

CAS#:

1327-41-9

Appearance:

White and yellow powder

Description:

Poly aluminium chloride (PAC) is a new type high efficiency inorganic polymer coagulant, adopting advanced manufacturing technique and quality raw material, show the features of low impurity, high molecula weight, and superior coagulating effect.

 

Different grades of Polyaluminum Chlorides (PAC). The highly charged Al in the products is optimized for best performance for the different basicities of PAC.  The low to medium basicity products are effective coagulants for treatment of both drinking water and waste water. And the medium to high basicity products are excellent for all ranges of wastewater treatment.

 

 

III. Poly Aluminium Chloride Application:

 

1. Its purifying effect on low-temperature, low-turbidity and heavily organic-polluted raw water is much better than other organic flocculant, furthermore, the treatment cost is lowered by 20%-80%.

2. It can lead to quick formation of flocculant (especially at low temperature) with big size and rapid precipitation service life of cellular filter of sedimentation basin.

3. It can adapt to a wide range of pH value (5−9), and can reduce the pH value and basicity after processing.

4. The dosage is smaller than that of other flocculants. It has wide adaptability to the waters at different temperatures and at different regions.

5. Higher basicity, lower corrosive, easy for operation, and long-term use of non-occlusion.
