All users can not unlock possible reasons:
A check the door to the power supply, the door to the electric lock connection is good;
B. Check whether the unlocked circuit is connected. Directly press system line 2 and digital line 3, and the unlocking line to the electronically controlled lock is a 2-wire cable. It is recommended to use a 0.5 square millimeter sheath cable. Slightly different manufacturers, there is no uniform standard;
C to the decoder main link failure processing method can not unlock <br> <br> indoors:
First, correctly connect the wiring diagram of the transmission line and can be used in the field test unlock password to unlock the way, if we open the electric lock, door machine to prove the electric lock channels operating normally <br> <br> other attention problems
A. Earthquake-proof wiring problems: Most building intercoms use terminal posts or screw-pressed wiring. Earthquake protection is also a key. In practice, many intercom hosts are found on the door of an event. Frequent shaking occurs with the opening and closing of doors. This type of problem is generally caused by poor contact due to vibration; the second reason is that the line is not protected by the sheath in the active joint of the door frame and the door leaf. When the door leaf is opened and closed, the circuit is pinched or severely worn and the system is disconnected. Or short circuit; no matter where the intercom host is installed, shockproof and wiring must be handled well, we recommend that you install the intercom host on a very open door or inline installed in the wall;
B. Unlocking line problem: The unlocking line (to electric control lock line) of most building intercoms is connected to the electronic control lock from the intercom mainframe. This type of wiring has many advantages, which is strong and can prevent damage and unlock the signal stability. However, there are also some kinds of interlocking lines for building intercoms. Another type of connection is to connect the three-wire cable from the intercom host to the system power supply, and then connect the two-wire cable from the power supply to the electronic control lock. The general building is The intercom power supply can not be installed on the door (most of them are concealed on the wall near the door, etc.). This kind of unlocking problem may appear in three aspects: intercom host, power supply, and unlocking line (now electronic control The quality of the lock is relatively stable, with few problems. For the time being, we do not show the diagram. According to our experience, the fault is mainly concentrated on the power supply and the unlocking line. In case of this type of connection, please check the unlocking circuit first, and then consider the replacement. Power testing, and finally consider intercom host;)
Some users can not unlock possible reasons:
Check whether there is any wrong connection or poor contact on the unlocking line (digital system: line 3 of extension to decoder; direct type: extension to line 2 of the entrance machine) and whether the extension itself is normal. Mark the unlocking line for each manufacturer. is slightly different, there is no uniform standard; approach: replace a good way to see the replacement machine is normal, if not properly check the wiring is connected correctly <br> <br> other attention problems
A. Some users can't open the lock. The general problems are mainly in three aspects: line, indoor extension, and floor platform; first, the extension that can't be unlocked should be checked to see if there is a bad connection (previously, no If the connection is wrong, only bad contact will occur. Use the universal meter to fix it; secondly consider the quality fault of the indoor extension and replace the same type of indoor extension test (small note: the extension has its own decoding and needs to recode the address code). In this unit other users can get an indoor extension to get the test; finally consider the floor platform failure, also use the same type of floor platform test (small note: most floor platforms have address code, need to re-encode)
B. There is no building intercom system on the floor platform. It is generally impossible for some users to unlock! Once it appears, all users can not open the lock and other serious situations, the solution: disconnect all wiring, and then press the intercom project wiring diagram, access the building intercom system from a new household, re-commissioning can be resolved; if occasionally Some users can not use, usually indoor extension fault, please replace the indoor extension;)
Parts normal weathering and wear <br> <br> in our daily inspection repair work, we found serious problems of natural weathering and normal wear and tear issues a large number of non-visual building intercom host earlier installed for this Some hosts, we recommend the following: correctly guide the owners to use the system equipment properly; pay attention to the host's waterproof work during installation, prevent rain, cleaning water into the host; to the security guards, cleaners to teach basic building intercom system knowledge, To facilitate daily supervision and maintenance.
