How to install an access control device

  • Access control in security and protection places has a very important role in the movement of people. Use of access control devices can be the best choice for corporate managers so they can easily monitor the route of traffic online without being present. In this article we want to talk about how to install access control with magnetic lock, access control Virdi AC2100 Plus, exit button and access control Virdi SR 100 FP. The plan we want to implement in an organization to control the door is as follows (Figure 1).
  • If you want to control personnel traffic from both sides of the door, you will need two sets of access control devices. (e.g Virdi AC2100 Plus and Virdi SR-100 FP / Figure 1-1). Now, if you want to control personnel traffic only one side of the door, you need to have an access control device and an exit button key (Figure 1-2).

Introducting Magnetic Lock :

Palizafzar’s magnetic locks consist of two output wires in black and red. Red wire requires 12 volts and black wire use for connecting GND (Ground).

To install fingerprint access control device and magnetic lock, it’s best to use separate adapter for each one. So in case of failure electronic lock control system continue to work. If the adapter of fingerprint access control device be damaged, the electronic door will continue to work continuously. The electronic door will continue to operate continuously without interruption because the Magnet Lock uses a separate adapter.

Why do we need to use separate adapters ?

  • Suppose that you use just an adapter for magnetic lock and access control Virdi AC2100 Plus, use an adapter and the corresponding wiring on the back of the traffic control device. In this case, there is a risk the electronic magnetic lock always sends 12V output to access control device for this reason we use separate adapters.
  • Note: Since the electronic door always has a 12V voltage on it and by fingering the relay disconnect communication for a few seconds until the door opened, Always keep in mind that with disconnect the main power of building, the door always will stay open. Therefore, it is recommended to use UPS to maintain security until happen cut the power magnetic lock continue to work with feeding UPS.

Important indicator of choosing an appropriate time and attendance device

Today, identification and recording of entrance and exit time of personnel at workplace is carried out using a biometric time attendance devices (such as fingerprint, face recognition, Iris scan and palm patterns) and contactless card attendance devices.
But what kind of device is suitable for you between these various types of time attendance devices? In the following we will look for important indicators of choosing a time attendance device. So you can select an appropriate time attendance device for your organization with full knowledge.
What are important indicators of choosing an appropriate time & attendance device?

Types of time and attendance devices:

At the first you need to know how much are important for you security and employee presence at work. Time attendance devices are divided into two general categories of contactless time attendance devices that include a card reader, and biometric attendance devices include fingerprint identification, face recognition and iris scanning.

Consider location and working environment:

If your organization is made up from several different sections, you can use several time attendance devices for ease of time tracking or buy a time attendance device and install it in a place that everyone has easy access to it. Also the work environment has an important role for choosing a time attendance device. The sensor of a time attendance devices are equipped with standard IP65 and they are anti dust and water. There is no problem to installing a time attendance device in outside of building that it has dust or rain. But in environments such as wood workshops or hospitals and occupations that deal with human physical components) such as hands) or possibility of transmitting a disease due to infection with contact fingerprint by touching the sensor of a time and attendance device. we offer you to use a face recognition time & attendance devices Palizafzar.

Selection a time attendance device based on number of personnel:

Choosing a device based on number of personnel is one of the most important option that should be considered when we are buying a time attendance device. If your work environment is with a staff of over 500 people, here is very importance to choice a device with technical specifications and high speed of the processor and you should use advanced time attendance devices but if you have fewer than 50 employees, you can use fingerprint or card time attendance devices.

Time attendance device price:

Price is another indicator to choice a time attendance device. Depending on extend organization and level of security, you can choose an appropriate attendance device from other devices. Usually card attendance devices are cheaper than biometric time & attendance devices (such as fingerprints, face recognition, palm patterns and Iris scans). Biometric devices in addition to the technology of identification type use other components such as capacity of logs, number of fingerprint and number of the face and speed of the processor at time of pricing.
