. Aolang Mu ALARM equipment installation guide <br> <br> a door magnetic detector installation requirements:

1. The door magnetic detector is installed on the door frame of the door or window that you need to control, that is, the door magnetic detector (main part, accessory) is fixed on the frame of the door and window. 2. The false alarm rate has a great relationship with the installation location. The recommended installation location should be a gap of ≤ 2mm between the main part and the subsidiary part.

2. Infrared detector installation requirements:

Infrared sensors can only be installed indoors. The false alarm rate is greatly related to the installation location. The correct installation location should be 2.0-2.2 meters from the ground; away from air-conditioning, refrigerators, stoves and other sensitive air temperature changes.

a) The infrared probe should be installed in the corner of the room as far as possible to obtain the optimal detection range. There should be no screen, furniture, large bonsai or other partitions within the detection range.

b) The infrared probe should be at a certain angle with the indoor running line. The infrared probe is the least sensitive to the radial movement reaction, and is most sensitive to the tangential movement (ie, the direction perpendicular to the radius). Selecting an appropriate installation location on site is an extremely important step in avoiding false alarms in infrared sensors and obtaining detection sensitivity.

Three. Household gas leak alarm installation requirements:

a) Install and use:

i. First determine the proportion of combustible gas and air, and then the alarm is fixedly installed in a suitable location within 1.5M from the gas source radius: A. Gas: lighter than air, floating at a high place; B. Natural gas: lighter than air, Floating in high places; C. Liquefied petroleum gas: heavier than air, deposited in a low place;

Ii. After the power is turned on, the alarm sounds, and the power light is always on. The function light flashes green and turns off after about 2 minutes, indicating that it has entered the alert state. When a gas leak is sensed, it is issued.嘀 嘀 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警 报警

Iii. If the sensor malfunctions, the alarm will sound a long beep and the function light will be yellow and long. After the fault is removed, the alarm will automatically enter the alert state.

b) Note:

i. Do not install outside;
Ii. Do not install in places where the air flow, ventilation fan, door, etc. have a large amount of airflow;
Iii. Do not install it in a place where the temperature exceeds 10~50°C or it is relatively humid;
Iv. Do not install where items separate the alarm from the gas equipment;
v. Avoid the use of solid spray adhesives, insecticides, paint binders, dilute alcohols, etc. near the alarms;
Vi. If the alarm malfunctions, do not disassemble and repair it yourself, notify the supplier or the nearest agency.

IV. Smoke alarm installation requirements:

1, installation and use:

● Select the surveillance area and place the alarm on the roof or ceiling of the surveillance area.

2. Note:

● Do not install outdoors;
● Do not install in places where the air flow, ventilation fan, door, etc., have large airflow;
● Do not install in a place where the temperature exceeds 10~50°C or is relatively humid;
● The alarm installation position must be more than 0.75 meters away from the corner;
● must be dust-proof, moisture-proof;

3, maintenance:

● Due to dust and other factors that may cause the alarm sensitivity to degrade, frequent testing and maintenance must be performed:
● Test the alarm once a week, press the test button;
● Clean the alarm once every six months: Turn off the power and clean the dust with a soft brush.

Custom Precision Part

Custom precision CNC parts refer to precise metal parts manufactured using computer numerical control (CNC) machines. These parts are typically used in industries such as aerospace, automotive, medical, and electronic equipment. CNC machines use computer software to control the machine tools and produce parts with high accuracy and precision.


Custom precision CNC parts are designed to meet the specific requirements of the customer. They can be manufactured using various materials, including metals, plastics, and composite materials. Custom CNC parts can be produced in various shapes and sizes, with tight tolerances and complex geometries.


One of the significant advantages of custom precision CNC parts is their high precision and accuracy. The CNC machines use advanced technologies, including laser cutting and high-speed milling, to produce parts with high dimensional accuracy and consistency. This is especially beneficial in industries where precision and accuracy are essential, such as the medical industry.


Custom precision CNC part offers an efficient production capability. The production process can be fully automated, allowing for the mass production of identical parts with high-end features. With CNC Machining, the parts can be delivered in a short time frame. This is beneficial in industries where demand for parts is high or time-sensitive.


Custom precision CNC part can be designed and produced for a variety of applications, including mechanical parts, engine components, medical devices, aerospace parts, and electronic enclosures, among others. They are also used in prototyping, allowing for the precise production of test parts before mass production begins.


In conclusion, custom precision CNC parts are essential in various industries, providing high precision, accuracy, and consistency in manufacturing. With the ability to mass-produce parts with efficiency and accuracy, these parts offer a powerful solution for a wide range of applications.
