What is an Access Control System?

The purpose of access control system is to grant physical entrance or access to a door in a building or open a gate only to those who are authorized or allowed access. The deadbolt lock, along with its matching brass key, has been the gold standard of access control for many years; however, today’s homes and businesses want more flexible access control.

Today’s access control systems not only allow you to control who enters locked doors and gates, but they also can be remotely monitored and manage access without physically changing keys. Keys have now passed the baton to computer-based electronic access control systems that provide quick, convenient access to authorized persons while denying access to unauthorized ones.

Basic Parts of an Access Control System

Many people new to access control may think the system is made up only of the card or PIN # used, card reader or keypad mounted next to the door or gate and magnetic lock or panic exit bar. There are a few more parts behind the scenes, all working together to create the magic of granting access to the right person.

Keypad/Card/Device/etc Door/Gate Access Reader – required

The most familiar part of access control systems are the cards, ID badges, bio-metric readers and more recently, the smartphone apps that emit a chirp or beep when presented at a card reader and unlock the door. These are also known as credentials since they bear the user’s data that tells the reader to grant you permission to be on the premise, or in other words, that you are an authorized entrant.

Access cards are typically proximity cards that, rather than being swiped or inserted like credit cards, are held two to six inches in front of the card reader. The same procedure is followed for phone apps. The benefit of using credentials is that they are personalized, so any unlock event can be traced back to the person associated with it.

Electronic Door Locking Hardware – required

Electronic lock/unlock hardware is used to either lock or unlock a door. The 2 most common types of electronic locks are called fail safe and fail secure.

Fail safe locks are used to keep a door locked by use of electrically charged magnetic plates and unlock when a request-to-exit (REX) button mounted near the door is press and/or power is removed.

Fail secure locks are used to keep a door locked by a latch and unlock by use of panic bars or levers mounted on the door.

The choice of which to use depends on the area being secured. Entry doors call for fail safe locks, since they need to comply with building codes and fire regulations, that call for people to be able to exit at any time, even in the event of a power outage. IT rooms should be wired fail secure because they need to remain locked at all times, even in the case of emergencies. Fail secure doors also need to be equipped with electrified push bars to allow people to exit quickly in case of a fire.

Request to Exit Buttons and/or Push to Exit Panic Bars – Required

A request to exit, push to exit button or panic bar, opens the door and ensures everyone inside can always exit the building in case of an emergency. The button or bar is typically installed on the inside or exit side of the door as credentials are not verified when the button or bar is pressed. Motion sensors can also be installed at the door and used instead of having to press a button.

Access Controller – Required

Access controllers or access control panels are the centralized control centers that connect the all door access components together. These control boards hold the configuration settings, log events, process requests and trigger the doors to unlock in the correct situations. Advanced access controllers support wired Ethernet networks and can be monitored and administered using a Windows PC app.

Access Control Power Supply Controller – required

Access Control Power Supply Controllers carry enormous importance in electronic access control systems – they keep fail-safe type doors locked. Some also provide power to the reader.

Low Voltage Cable and Wiring – required

Cables are one of the most important parts of a good access control system as they deliver the signals and voltages required by the components. Proper wire type, gauge and size are vital for proper operation depending on the distance, type of signal and power requirements needed.

Door Access Control System Installation – required

Installation cost can vary substantially depending on the type of door or gate. Everyone knows what a door is, however there are often three types of doors: Glass, Metal or Wood doors.

Glass doors are the most difficult to install access controls on. As the name suggests there usually isn’t much of a frame or hidden area where a lot of wiring or mounting of the door lock can be hidden. Extreme care must be taken when drilling into the frames and working around the glass as it’s easily cracked. As such, these installations are generally the most labor intensive and as such more expensive.

Metal (or steel, alluminum, etc) doors can also be difficult to work as sometimes the frames are fairly solid and may not have cavities that are accessible. Generally these are of moderate difficulty and not as expensive as a glass door but possibly more expensive than a wood door.

Wood doors are generally fairly easy to work with but may have some challenges in the construction, existing mounted hardware or sensors installed on the door.
