Access Control System Troubleshooting and Essential tools

Problems with door access control systems are very common happened when you are processing access control system installation, even you can find a lot of problems with magnetic locks, electromagnetic door lock troubleshooting or card access troubleshooting, so here some troubleshooting methods and essential tools for you.

Common tools

1,Multimeter, Purpose: To check if the voltage is normal and if the circuit is short-circuited or broken circuit.

Prepare a set of access control systems equipment:

485 and TCP communication mode controller*each one

ID and IC card reader*each one

Several ID cards and IC cards

NONC*1, 485 converter*1

Standard power supply (12V, above 5A)*1, Purpose: For the substitution test

2, Small flathead screwdriver, Purpose: Use to remove the wires off the terminals.

3, Cross screwdrivers

Purpose: Disassembly the controller plate, case and power supply, etc.

4, Notebook: Must be with a serial port or USB serial port converter and network port.

Purpose: For excluding test. Exclude the faults or operation systems problems of the user’s computer itself

5, Network HUB: (two or three directly connected cable with modular plugs)

Set up a small LAV environment to test if the TCP controller has communication problems

6, Test pencil: To check if there are electric leakage of the computer and controller case. To find out the location of the AC live wire.

7, 120Ohm terminal resistance, Improve the anti-jamming capability of 485 circuits on some special occasions. Preparing several pieces are enough.

8, Interphone, It used to provide convenience for people on different floors to check the faults and communicate. Not required, can be replaced by cellphones.

Common used methods

1, Software testing:

Testing method:

First, start the management software to enter the【Central console】and select the faulty gates. Then click 【Test】. The information from the running software will display relevant faults, and you can troubleshoot them accordingly. For example, the software set up some advanced settings, such as open the door with multiple cards were set up under the condition that the user know nothing about, this will cause failure to open the door with the cards.

【Real-time monitoring】method: Select the door need to【real-time monitor】in the【Central console】

Real-time monitoring corresponds to the corresponding punching card indicator lights to find out the faults of failure to punch the card.

The corresponding communication indicator lights can better help with finding out the communication faults.

【】method: Select 【Controller】in the【Basic setup】

 Can find out the communication faults in TCP/IP controller

Indicator light method:

CPU indicator light

The CPU indicator lights is flashing when it works normally. If keeps lighting or not bright, there’s the possibility that the CPU is connected with the wrong power supply, or the controller chip has been damaged.

CARD indicator light:

As long as punching in any card reader under the controller and pass through the card number,the indicator light flashes. If the indicator light doesn’t respond after punching, the problems may be:

The circuit from the card reader to the controller is broken, or the data wire is connected wrong or connected reversely.

The output format of the card reader is incorrect.

The card reader is broken

The card reader’s input port of the controller is broken.

ERR fault indicator light:

The light is not bright under normal condition. If the light flashes or keeps lighting, the problems may be:

The chips in the controller probably burn out, storage disorder needs to format, or other faults. Please contact the manufacturer’s technician.

Communication indicator light:

485 controller

Rx light indicates the controller receives signals (including normal and interference signals)

Tx light indicates the controller emits signals.

TCP controller:

Rx (Link) light, keep always lighting indicates there are no problems with wires connecting. (It is also possible that there are some special problems that have not been detected and can only be said to be basically normal.)

Tx light, flashing indicates being communicating.

Substitution method:

Equipment substitution method:

Replace the faulty equipment with a device that is sure of good (usually tested, often used) to see if the malfunction is gone.

If it goes away, it’s possible that the device is broken. But it’s not entirely certain, because if it’s an environment or something that causes a failure, it doesn’t necessarily show up right away, or it’s going to hurt the new device for a while.

If the device in question, separate test no problem, this may be related to environmental problems such as wiring. One should actively continue to find out the fault source. Do not think that change the equipment means everything is all right.

Notebook substitution method.

Can check out if there are problems with the user’s computer or operating system or with the wrong setup.

Exclusion method:

If there are multiple devices, and only one device finds out with a problem, if it’s not the device problem, there must be something outside of it that causes this specificity.

If there is more than one equipped with the same problem, it is unlikely that all of the equipment will be broken, and there must be one and the same factor that causes all equipment to have the same failure characteristics. So finding the same point is the key to finding the source of the failure.

If there is more than one equipment in a system and you are concerned about the cause of the malfunction due to mutual influence, consider using dichotomy to evacuate all equipment, which helps to speed up troubleshooting. For example, A system has 8 controllers, consider disconnecting the back of 4, then disconnect the remaining 4 of the two

What Is The Purpose Of A Door Access Control System?

Whether it is your work place or your home, it is always necessary to restrict the entry of unwanted people in the premises. For this use of mechanical locks and keys had been in use for decades now but they had certain limitations. It is now possible to overcome those limitations by using door access control systems.

1, What were the limitations of mechanical locks and keys?

The main purpose of using mechanical locks and keys is to control those people who are entering some premises. The whole thing of entry and exit into premises was done manually where someone with the key controlled the operation of the lock. However, the main problem of lock and key was that there was no record of who is entering when. If the person who had the key considers and allows even someone who is not supposed to access nothing can be done. It cannot be recorded also. And this is the main limitation of the mechanical locks and keys.

Apart from that, it is possible to forge the keys. If someone wants illegal entry they can somehow forge the key and when required unlock the locks. Thus, the mechanical locks and keys although provides protection cannot make it complete. And this is where the use of door access control systems becomes so important.

2, What are door access control systems?

In simple words Door access controls are all about who, where and when? It is the door access control that is pre-defined about who is allowed to entry or exit a security gate. The areas where they are allowed is also controlled by it and the timings when they can enter and exit can also be fixed. Thus, they are the systems designed for restricting the physical entry of users who are permitted to enter and exit any place at any particular time. The goal of access control is to control the individuals who are gaining permission for entry. With this, it also becomes possible to determine the purpose for which an access control system is used.

3, What is the purpose of using an access control system?

Whether it’s a private office or high-security zone, it is very much necessary that the people entering and exiting them are controlled and that is what is done by an access control system. It is the main purpose of access control. This has been done by the brass lock and keys for years. Now the whole system has become more sophisticated. They are now electronic devices that are controlled and maintained by computers. The software is fed with different data and these access system decides whether to permit or not someone for passing through the entry. However, you will find much more access control purpose. They are discussed below.

  • Apart from maintaining the basic purpose of controlling the people using the passage it also reduces the man power that is required for controlling the entry and exit. It can be set at different key doors and that helps in controlling passage.
  • It ensures security in the premises and the main goal of access control is to minimize the risk of unauthorized access of individuals to some workplace. Whether it’s a computer data or entry and exit to a particular place, say a laboratory, with the help of access control it is possible to ensure the security of the place better than using a mechanical lock and keys.
  • An access control system also allows internal levels of security. It makes it possible to give access to one individual for any particular level and then if required cannot allow them further to any more level. This can be easily controlled with the software that will make it easier for the management to control access of their employee or even outsiders.
  • Another purpose of access control is to have a check on the time when the entry and exit is made. It makes it possible to keep know even in future about the timings when someone has taken entry or has left the premises.
  • An access control system is also used for taking control where there are multiple entry and exits. With the system working anyone can enter the premises from any point but that will be recorded in the system.

While discussing the access control purpose it is clear that an access control system is a better security system for any organization. Thus, such systems are implemented in private offices as well as government offices. They ensure that the entry and exit of individuals be that employees or visitors is not only controlled but recorded. It gives someone authorization with which they can enter at the required time without even worrying about getting permission from someone as they are authorized for doing so.

Benefits of Access Control Systems

Electronic Access Control Systems grants access based on the credential presented. At the point when access is in truth, the entryway is opened for a foreordained time, and the exchange is recorded. At the point when access is cannot, the entryway remain bolted and the endeavored access is recorded. The framework will likewise screen the entryway and alert if the entryway is constrained to open or held open too long after being opened empowering you to oversee who has access to your building or particular regions of the building.

Access Control Systems function by using identification controller boards, lock power supplies, and other mechanisms to control cards, keypads or in situations where a higher level of protection is needed for fingerprints or other biometric readers.

Benefits of Access Control Systems include

1, Access control systems make sure that only authorized personnel or users can have access to a specific resource. For example, a big organization that has a wealth of resources and data in several rooms in a building can install access control systems for each room to control access to those rooms. Only employees who are registered into the system can go in and out.

2, This technology guarantees that only the right people can lay eyes on sensitive information and handle expensive equipment in the workplace. Access control systems also record entries and exits, so it would be easier for managers and business owners to monitor and locate their personnel at any given time.

3, There is also a way to make sure that those who have access have a limited amount of time in individual rooms. This will help cut back on unauthorized entry and over time. In case something goes wrong and security was breached, you will know which employee entered the room and at what time. Detailed reports from the access panels will give you all of the information you need.

4, The other benefits of this gadget are to the many gadgets that already comprise your home security system are numerous. For one, it only allows people who are authorized by such a system to open your doors. Even then, these people are limited to doing just that, opening doors when they need to open them.

5, Individuals who have primary control over such a system have more than just door opening powers granted to them. The master of the house can change passwords, activate and deactivate security systems, check cameras and what these have recorded and other similar actions that they may want to undertake with their security system. These individuals can also restrict system access to any person, add gadgets to the home automation system, and other similar tasks.

6, What access control can do for you and your family is by increasing the security of your home by giving only the occupants the rights and privileges to open doors and activate gadgets. It can also help to limit the number of people who can restructure the security settings of your house to only one, which can greatly increase the defense of your property. This can even help keep your house thoroughly protected even when the entire family is away. No one can enter if they are not authorized at all to enter, and any attempt to do so is related to the primary keeper of access control as well as to the security company monitoring your home.

Smart Cabinet Locking System

For a very long time, people have been trying to lock away important property such as documents, certain merchandise and even poisonous chemicals and drugs from other people. Unfortunately, for a very long time, we have grown to know, understand and use regularly, the mechanical locking systems that have been engineered by different security companies. However, unfortunately, these mechanical locking systems come with their faults, including high maintenance and repair costs, high installation costs and a lot of time wasted in the installation. It is not a surprise finding out that these mechanical locks have undergrown minimal advancement over the many years they have been in use when the things that should be locked away have grown to be more valuable as time goes by. A lock and key system have proven to be untrustworthy and unreliable and people have been trying to find better security solutions to replace the old security systems. Fortunately, technology is here to advance everything including security. Smart cabinet locking systems are not in play and they have been in integrated into many individual and company cabinets.

Smart cabinet locking systems are definitely much more expensive as compared to the older mechanical locking systems and the lock and key systems that people have grown accustomed to. Fortunately, this high cost you will have to incur is worth it because there is no way a thief will crack the code or go through your smart lock. Before you consider the beefed up security, consider the look. The smart cabinet locking systems get rid of the lock and key systems which means that unless you have the smart card, fob or your smartphone, you cannot tell where the lock opens up from. This means that the lock leaves no clue to anyone who would want to access the cabinet without your permission. As a result, a beautiful and completely smooth appearance is maintained.

Let’s talk about how they work. Smart cabinet locks are unlocked using the fobs, smart cards or even smartphones you get to carry around with you. These three have replaced the original metal keys or codes you have to memorize. Instead of driving a key in your lock or even having to put in a combination of codes, you can simply point your fob or smart card at the smart lock and the lock will automatically give you access. This is very important in controlling access control and loss control. In addition to that, the lock saves you a lot of time. The smart locks are known to provide the most durable solutions for individuals and companies.

When using the older security solutions, locking your property and valuables away meant closing the lock manually using your metal key. Fortunately, this is not an issue with the more advanced smart cabinet locking systems. This is because once the door to your cabinet has been pushed back to close the cabinet, the lock automatically locks your things away and it will require the fob, card or phone to gain access again. The security therefore is completely guaranteed and you can rest easy knowing that your property is safe.
