With the rapid development of science and technology, more and more smart products have gradually come out, and the emergence of anti -theft alarms has brought people more and more personal security guarantees.It is worthy of a complete set of anti -theft alarms, but there are many brands of anti -theft alarm in the market. We should master some purchase techniques. At the same time, we must also understand the installation methods of some alarm systems. Let ’s take a look!
How to buy anti -theft alarm
1. With national compulsory 3C certification
The safety performance parameters of the family anti -theft alarm system are crucial. Safety technical prevention products that have not obtained compulsory product certification and have not applied for the Chinese Mandatory Certification (CCC Certification) logo are prohibited from selling and use in the market.It should be noted that the 3C logo is just the most basic security certification, which does not mean that the products use performance is excellent.
2. The quality assurance with low error report commitments
Family anti -theft alarm products are mainly an intelligent alarm system composed of alarm host and detector. The alarm function of different products is different, but any product needs the common role of the host and the detector to accurately prevent the alarm. Otherwise, it will cause mistakes.Report.Therefore, from the perspective of manufacturers, high -quality products must have advanced soft and hardware technologies, advanced and mature production testing processes and equipment, so as to ensure the stability and reliability of the product.
3. Has a reserve power supply 24 hours after power -off
The alarm host is a transit station for receiving the detector signal and a alarm signal. All the alarm hosts work normally under the power supply mode of an external power supply.If the power outage or the power supply is broken, the power supply is extremely critical.The alarm host with a reserve power supply for 24 hours after power is disconnected can play a role of anti -theft alarm.
4. Wireless forwarding alarm function with anti -destruction and shearing lines
Except for the GSM global mobile alarm host in the market, other alarm hosts need to use the inherent telephone communication lines in the city. What should I do if the telephone line is cut or the telephone line is faulty?Therefore, the alarm host should have a wireless forwarding function.
5. Have the automatic detection of faults and prevent leakage function
Will the anti -theft alarm work work normally after the alarm has not been alarm for a long time?How can I simply know whether the anti -theft alarm is working normally?The fault self -test of the anti -theft alarm is a mutual detection between the detector and the host, so that the alarm can automatically detect whether the alarm work is working properly after a long time without alarm.
6. Having home appliance control function with home appliances
In addition to high -quality anti -theft, fire prevention and anti -gas, anti -theft alarm products can also achieve smart home appliance control functions, and gradually become one of the elements of users to buy products.Now some anti -theft alarm products on the market already have practical home appliance control functions. For example, the automatic turnover of home appliances such as lighting and air conditioners can be easily turned off through infrared signals.
How to install the anti -theft alarm system
The alarm host is a non -explosion -proof type and cannot be used directly in hazardous places Ⅰ, Ⅱ, and III, otherwise danger may occur!The alarm host is near the device near the TV, air conditioning, computer, microwave oven and other strong electromagnetic radiation equipment, so as not to affect the receiving of the antenna.
1. Basic requirements for system installation design
(1) Installing design, according to the protection requirements of the required protection area, select the type of detector type, model, etc.
(2) According to the effective protective area and on -site environment of the detector, determine the installation location, angle, and height of the detector, and require the detector to be installed at the hidden position as much as possible under the condition that meets the protection requirements.
(3) The wiring should be hidden as much as possible to avoid being destroyed.If the light line should be protected by lines or plastic tubes to prevent damage by rodents.
(4) The construction drawings shall indicate the model specifications of the detectors and optical cables in each defense area, and indicate the use of various lines in the cable.
(5) Construction drawings shall be recorded for the record for system maintenance.
2. System installation and debugging
(1) Installation process requirements for infrared detectors
When installing, pay attention to the angle and height of the detector and the horizontal plane, which has a great impact on the protective area.Avoid air heat sources, such as hot and cold air outlets, air -conditioning air outlets, electric heaters, air -conditioners, etc.The detector should be directly seen on the scope of the protection and cannot be obstacle.The detector avoids straight doors and windows.In order to ensure the launching effect of the antenna, please pull all the launch antenna.
(2) Installation of the door magnetic switch
The door magnetic switch should be determined according to the minimum angle of the door. The distance between the magnetic block and the door magnetic switch should not exceed 10 mm.
In order to ensure the launching effect of the antenna, please pull all the launch antenna.
(3) Installation of the alarm host
The alarm owner should be installed in a hidden position, but it should be noted that the microphone and the built -in speaker position on the front panel of the host should not be covered to ensure that the sensitivity and the alarm sound are not affected.
In order to ensure the reliable operation of the system, it is recommended to configure a spare battery. If the power outage or power outage time is often used for a long time, it is recommended to configure a reserve power supply with a larger capacity.
In order to ensure the antenna receiving effect, pull all the receiving antenna.
Anti -theft alarm system fault investigation method
1. The central machine cannot receive all user alarm information
Possible reasons: The telephone line interference is too large, the telephone line noise is large, the telephone line has a short circuit, the circuit is disconnected, the anti -theft switch on the phone is turned on, the telecommunications bureaus communication failure, the host alarm center communication programming error, the center software serial port, the serial port line, the serial line line, the serial port lineConnection error, damage in the serial port, the failure of the computer itself.
Exclusion: Is there a short circuit and disconnection on the inspection telephone line, turn off the anti -theft switch on the phone, and check whether the central communication programming of the users host host is correct, including the central telephone number, center communication level, center communication format, user number, report options, report options, report options, report options, report optionsWait; open the serial port on the center software, correct the series of ports, check whether the serial port interface is damaged; check whether the computer works properly.Check whether the software is a trial version and check whether the trial expires from the software system log.
2. After the central machine receives the alarm information, the alarm cannot be up/down
Possible reasons: The central telephone line interference is too large, the telephone line is short -circuited, the circuit is disconnected, and the communication failure of the telecommunications bureau.The reposting number on the center software is incorrect.
Elimination: Check whether the telephone line interference is too large, the phone line is short, disconnect, and correctly fill in the dial number of the center software.
3. The host -defense or forced cloth defense triggers the wired front end, but does not report to the police
Possible reasons: The connection line error between the cable front end and the host, the lines occur short circuit, the circuit is disconnected, the front -end power supply voltage is insufficient, the tail resistance is not connected, and the attributes of the defense areas are not written or written.
Exclude: Correctly check the connection line between the cable front -end and the host, check whether the end resistance of the end of the line is not connected or connected, and use the multimeter to test whether there are short circuits, disconnecting circuits, and whether the front -end power supply voltage is stable.Writing the attributes of the cable front end.
