What is a Door Access Control System?

A door access control system is a system that will either grant access or deny access to someone based on set criteria like a password or key fob. It uses a database of permitted users and different methods of allowing access:

  1. Something you have
    This can be a keyfob, or magnetic card, or proximity card.
  2. Something you know
    This can be a pin code or password.
  3. Something unique to you
    This can be a fingerprint or retinal scan.

How do Door Access Control Systems work?

An access control system works by determining who should have access and when to an entrance. By using a keyfob, for example, on an access control reader, the reader reads the information on the keyfob and compares the unique identifier of the fob with a database of allowed users. If the identifier matches with one on the database, then the access control system tells the relay to switch, which in turn opens a door. The same method is used for pin codes and fingerprints etc., with a different type of database.

What is a Door Entry Sytem?

A door entry system keeps an entry secure after the access control system has either granted access or denied access to a person. Door Entry Systems enforce the decision to either grant or deny access to a person. It either keeps the door locked, or releases the door to allow entry.

How do Door Entry Systems work?

A door entry system works when the access control system has made the decision to either grant or deny access to someone. If access has been granted, the door entry system then reacts and a signal is sent to the electric strike or electrified lock to unlock the door and allow entry. If there is a panel that has an intercom system, an alert will be sent to a phone or speaker/video panel for someone to grant or refuse access instead inside the property or via a mobile app.

How do Electric Door Locks Work?

An electric door lock is a lock that will have a solenoid or a coil inside which will energise and create a magnetic field and force. This force is used inside the lock to release a latch or force a bolt that either releases the lock or it secures the lock. Electric locks can be both Fail-safes - which means that they are open when there is no current, or Fail-Secure - which means that they are closed when there is no power. There are many types of electric door locks (Strikes, Solenoid bolts, Electric Rim locks), but the fundamental working of an electric door lock is usually the same.

How can I Fix an Electric Door Lock?

There can be many issues with electric door locks that will stop them from not working correctly:

  1. Misalignment
  2. No power
  3. Faulty wiring
  4. Faulty lock
  5. Jammed lock
  6. Faulty relay

You will need to diagnose what the fault is before you can start thinking about what you need to change in order to fix it.

How can I install an Access Control System?
