Awareness of intelligent automatic dialing anti-theft alarm system
Many users do not understand the anti-theft alarm system and think that it is a particularly complex system. Some users think that only bank gold stores can afford it. This is actually not the case. With the continuous development of science and technology, the current product is from the price point. To the function, it can be applied to our daily life. Let us take a general look at what a burglar alarm system is.
Alarm host: The alarm host uses the physical method or electronic technology to automatically detect the intrusion in the deployment area. Once an illegal entry occurs, the control panel will receive an alarm signal and display the alarm's area. The alarm host is an anti-theft device. Core facilities.
When installing the alarm host, you need to pay attention to several aspects:
1. The location of the alarm host installation must be empty, so that the alarm host can receive the alarm signal sent by each detector without the phenomenon of poor signal or even no signal.
2. The location of the alarm host should be concealed and not easily found 3. The connection line between each detector and the alarm host must be correct, and no wrong phenomenon should occur. Otherwise, false alarms or alarms cannot be reported. The alarm host should not be installed next to appliances with high frequency, because high-frequency appliances will emit electromagnetic waves, electromagnetic waves will interfere with the alarm host to receive normal alarm signals.
5 alarm host should be more than 0.5 meters away from the ground to avoid ground shielding interference
Wireless Door Magnet : The main components of the door magnet are the induction reed switch and the magnet. The door magnet is used to control the opening and closing of the reed switch. When the two are close together, the reed switch is closed. If the two are separated from the reed switch, the disconnection signal will trigger the RF circuit to send a wireless alarm signal to the control panel. The installation of wireless magnetic sensor is also a skill, you can view the wireless magnetic installation method this article, which describes in detail the need to pay attention to the installation of wireless magnetic sensor.
Wireless infrared detectors: detectors have a variety of infrared detectors, smoke detectors, gas detectors, etc., while wireless infrared detectors are devices that convert incoming infrared radiation signals into electrical signals. Infrared radiation is the wavelength between The electromagnetic wave between visible light and microwave is invisible to the naked eye. If one wants to perceive the existence of such radiation and measure his strength, he must convert it into other physical quantities that can be measured. The main use of modern infrared detectors is It is an infrared thermal effect and a photoelectric effect. The output of these effects is mostly electricity, or it can be converted into electricity by an appropriate method. An infrared detector has at least one object that is sensitive to infrared radiation, called a response element. In addition, it also includes a response element holder, a sealed housing, and a window that transmits infrared radiation. Sometimes it also includes cooling parts, optical parts and electronic parts.
The precautions for installation of wireless infrared detectors are as follows:
1. Wireless infrared detector should be installed 2.0-2.2 meters away from the ground when installed; avoid ground shielding interference.
2. Wireless infrared detectors should be kept away from places where the air temperature changes greatly.
3, wireless infrared probe should be installed in the corner of the room as far as possible in order to obtain the best detection range, the detection range must not have screens, furniture, large bonsai or other partitions.
4. The position of the wireless infrared sensor should be at a certain angle with the indoor walking line. The wireless infrared sensor is the least sensitive to the radial movement reaction, and it is the most sensitive to the tangential movement (that is, the direction perpendicular to the radius). Selecting an appropriate installation location on site is an extremely important step in avoiding false alarms for infrared sensors and obtaining the best detection sensitivity.
The above is the brief introduction of various parts of the intelligent automatic dialing anti-theft alarm system and the places to pay attention to during installation. Therefore, we must be fully prepared when installing the intelligent automatic dialing anti-theft alarm system to prevent false alarms caused by installation errors. Or it is not a phenomenon of alarm.
