A: Before the “attached invisible cable†was introduced, the renovated environment can only install wireless detectors or do not install anti-theft alarm products. The reason is that the installation of wired anti-theft alarm system will undermine the effect of decoration. This is not acceptable to every owner who has finished the renovation. Even if the "wall-by-wall wiring, blank cover," can not achieve the desired results, and time-consuming and costly. The advent of "attached invisible cable" solved this problem for engineers. The "attached invisible cable" has 3M double-sided adhesive on the back, which can be attached to various wall surfaces, such as: Wood, wallpaper, marble, paint, glass, cement, etc., easy to paste, lasting effect, saving labor costs, greatly reducing the impact of wiring to the environment.
2. Why can't I install wireless alarm?
A: There are many problems that cannot be solved, whether it is the domestic or imported big-name wireless alarm systems, such as:
1) Same-frequency interference: When multiple wireless detectors are installed in the same household or several adjacent wireless alarm systems with “315MHZ and 433MHZ†installed in the same frequency band, the same frequency interference will occur, one of them will be triggered, and the alarm host will not be able to receive other detections. And remote control signals. If someone is active at home, and the detector is triggered, then neighbors want to use the remote control to “arm†or “disarm†or have criminals invade their neighbors. Although the detector “alarmsâ€, the control panel will not respond. In another case, if the criminals are more professional and continue to trigger their own remote control or mask to send out the interference signal, the wireless host will not receive the wireless detector alarm signal, and the entire wireless alarm system is in a paralyzed state. This is wireless. The most fatal weaknesses of the alarm system, the more wireless alarm products are installed, the more severe these situations are.
2) Wireless Shielding: The use of "Electronic Wireless Shield" can shield the wireless signal, and the wireless alarm system is also paralyzed and cannot work normally.
3), garbled: Due to strong co-channel interference at 315MHZ and 433MHZ, when the hashed coded signals are mixed together, it is possible to mix pulses that are consistent with the encoding of a wireless alarm system. Strings, this situation will lead to false alarms in wireless alarm systems.
4) Battery-powered: When the battery is exhausted, manual replacement is needed to increase maintenance costs; due to the professionalism of commissioning and maintenance of the alarm system, it is difficult for the average consumer to replace it, and it is inconvenient for the user to use it. Some manufacturers still do not have a reminder function because the technology is not in place. When the battery power is too low, there is no reminder function, or the reminder function is not paid attention to by the householder. As a result, a thieves cannot enter the wireless detector but can't report the alarm to the owner. In addition, due to battery power, the wireless alarm system can only use wireless infrared detectors with low power consumption and high false alarm rate. Nowadays, many companies have launched wireless dual-channel detectors with 220V power supply. Since they can deploy 220V lines, they can also use weak wires. This is not a true wireless alarm system, and it still cannot solve the interference problem.
5) Critical signal: When the distance between the wireless detector and the wireless host is at the “signal critical pointâ€, with the battery power shortage or the environment changing, the host may sometimes receive an unstable signal that sometimes cannot receive the detector signal. At this time, there will be missed reports.
3, "attached stealth cable" can really be invisible it?
A: The "attached invisible cable" is not invisible in the true sense. It is invisible because it has an installation thickness of less than 0.4mm and a width of 6.25mm. It is available in white, black, and transparent colors. This ultra-thin, same-color The characteristics are attached to the concealed corners and corners. It is difficult to notice the presence of wires in the absence of attention.
4. Is the "attached invisible cable" too thin for transmission?
A: The "attached invisible cable" has several specifications. The longest used is composed of 0.1*0.8 mm pure copper-plated flat copper wire. The impedance is 0.27Ω per meter. After theoretical calculations and actual tests, a 12V 40mA DC load is loaded. (such as infrared microwave Shuangjian detector current 35MA or so), 50 meters distance, pressure drop is less than 1V, this type of detector can work normally above 9V, can fully meet the wiring requirements of weak engineering, 50 meters distance even if Villa uses line and is enough.
5, so thin, how to peel and wiring?
A: "Patch-type invisible cable" can not be directly connected to the detector and the host terminal, its line skin thickness 0.06mm, need to "pick-off stealth cable special peeler" peeled, and then through the "special adapter â€, received one end of the detector, the other end receives the defense zone interface of the control host through the “dedicated tapping fuse boxâ€.
6. What do you do when several lines meet?
Answer: The thickness of the "attached invisible cable" is not more than 0.4mm. If multiple lines meet, they can stick together or stick side by side.
7, how to connect to the main board, cable dedicated fuse box what use?
Answer: Under normal circumstances, 8 detectors are wired back to the host. Each detector has 4 cores and 4*8=32. The management is a headache. The front end of the “attached invisible cable†is converted into a 4*0.3 weak wire through a “special adapter†and is connected to the detector; the other end converts 32 lines of 8 detectors into 10 through a “dedicated tapping fuse boxâ€. Core (1 positive power supply, 8 signal lines, 1 common ground). Give a cumbersome wiring project a whole new idea.
8, can not be used for strong electricity?
Answer: No. "Patch-type invisible cable" can only be used for weak wiring below 60V1A. During the construction process, it can be operated as required to prevent short circuits. Each "patch-type invisible cable" must be connected to the "dedicated tapping fuse box" before it can be connected. Into the alarm controller. The “dedicated tap safety box†not only plays a role in simplifying the number of cables and short-circuit insurance, but also allows a maximum current of 1 A per cable to protect the equipment and cables from short-circuit damage.
9, a long time, will not fall off?
A: After the "attached invisible cable" is attached to the wall, it only bears its own weight, and it weighs 18g per meter. This weight is negligible; the sticking time of the double-sided tape, in addition to the quality of the glue, is also related to the air. The contact area is relevant. To achieve a long-lasting adhesion effect, we use 3M brand double-sided adhesives from the United States, and we have selected one of several hundred models for the most effective results by testing at the Guangzhou 3M Institute for tensile strength, peel force, and high temperature/humid environment. The best model. And develop a set of professional operating procedures, and finally use a special pressure reel, the line compaction, squeeze out excess air, to ensure that the cable attached to the wall more than 6 years, will not fall off.
10, how to do the wall off the white ash?
A: The wall surface of white ash will greatly affect the attachment strength of “attached invisible cablesâ€. To adapt to this situation, we need to use another method of sticking: The first step: use a brush to clean the surface of dust, do not use too much force In order to avoid too much ash off; the second step: the nitro transparent varnish diluted with water that day, with a small brush gently brush a layer according to the cable construction route; the third step: after 10 minutes, such as dry nitrocellulose paint, and then Carry out the wiring; Step 4: Use the roller to compact the cable and squeeze out excess air. This type of construction has a stronger bond and a longer service life.
11. What should I do if the wall is wet and there is water?
A: There is water on the wall surface, which forms a layer of water film between the double-sided adhesive and the wall surface, which affects the adhesive strength. There are two main types of water on the wall. One is a newly constructed house. The water vapor in the wall is not dry enough and it is not suitable for living. In this case, the scraping can not be covered, and the wall needs to be air-dried. The other is that due to the high temperature of the indoor air and the low temperature of the wall, the water in the air condenses to the surface of the wall to form water droplets. There is water on the wall. You can't directly attach invisible cables. After the wall is dry, dilute nitro transparent varnish and thinner water on the construction line. The lacquer can infiltrate into the wall and dry on the outside. The formation of paint film, this method can delay the use of years, do not worry about water on the wall.
12. What if the cable is not half attached? How do I know the length of the remaining line?
A: Prior to the construction of the project staff, it is necessary to choose a good route to achieve the best invisibility effect. At the same time, the length of the cable to be used is calculated. According to the cable size, whether the remaining cable length in the reel is sufficient or not, the “attached invisible cable†cannot be connected during the wiring process. Every meter of the surface of the cable is printed with a rice code. The length of the remaining wire in the cable tray can be known according to the “rice codeâ€. In order not to affect the “invisible†characteristics of the cable, we use the invisible ink printed rice code. Blu-ray light to see the yards.
Patch-attached stealth cable operation process and precautions:
1, choose to attach the route
Prior to the construction of the engineering staff, it is necessary to choose a good route to achieve the best invisibility. At the same time, the length of the cable must be used for calculation. According to the cable size, whether the remaining cable length in the reel is sufficient or not, the “attached invisible cable†cannot have connectors during the wiring process. On the front of the cable, there is a rice code of the remaining size printed every one meter, and you can use the equipped blue light to view the rice code.
2, clear the wall
On the back of the "patch-type invisible cable," US 3M double-sided tape is attached. In order to firmly attach the cable to the wall surface, be sure to clean the surface before attaching. Particles, dust, oil, moisture, etc. will reduce the effect of the paste. It is recommended to use isopropyl alcohol or ethanol (alcohol) to clean it and clean it before attaching the cable.
Note: If the wall surface is off the white gray wall, after cleaning with a brush, use a small brush coated with a layer of nitro transparent wall paint, and then paste and wait for the paint to open.
3, attached cable
10CM cable is reserved before the joint for the joint, tear off the release paper began to paste, paste, do not tear too long, torn a little sticky, so as not to be too long mis-adhesion to other locations. Paste along the designed route, leaving 10CM as a connector to the host. During the process of cable attachment, do not drag the cable tray on the ground and place it in a clean and gray position. Because the double-sided tape of the cable is easy to get rid of gray and affects the effect after attachment, it is recommended to use a dedicated cable tray clip.
4, roller compaction
In order to achieve a better adhesion effect, the line is affixed with a "special pressure reel" to compact the line. It is recommended to apply a pressure of 1 kg/cm2 or more. After 20 minutes of adhesion, the performance of the double-sided tape is achieved. 50%; the best effect of the cable attached to the wall is 72 hours after the adhesive is applied, and the strongest glue is used. Do not apply extra stress to the double-sided tape during this period.
5, construction temperature
The ideal construction temperature is 20°C~30°C. If the construction temperature is lower than 10°C, the initial adhesiveness of the cable will decrease and the bonding effect will be poor. If you need to operate in a low-temperature environment, be sure to heat the cable, such as through the oven, hair dryer and other equipment, and then paste.
6, cable storage
To prevent overfilling, cable storage temperature is controlled at 15°C~30°C and humidity is controlled below 50%. Use up a roll and open a new roll of packaging. Use it to put it back in the bag and seal it. Adhesive overflow is mainly affected by humidity, temperature problems are not large). At ideal conditions of 20°C and humidity less than 50%, the cable has a shelf life of 2 years.
