Access Control Systems FAQ
What is a physical Access Control System? Faq arrow

An Access Control System is a device that allows users to present credentials or call tenants in order to gain access to a secured area (a door or gate, for example).

How does an Access Control System work? Faq arrow

An Access Control System provides a method for a User to present some type of personal identification (Entry Code, Card, RFID tag for example) which is then compared to a programmed database to verify whether that User is to be granted access at the entry point on that day at that time. If the proffered credential matches the information in the database, the system will activate a device (such as a Relay) which will then unlock a door or activate a gate operator to grant the User access to that entry point.

Some access control systems have a telephone feature that allows guests to call tenants. The tenant can then grant access to facility by pressing a DTMF (Dual Tone Multi-Frequency) key on their phone. If denying access, the tenant simply hangs up the call.

How to install an access control system? Faq arrow
The various elements of the system (Input Device, Entry Control Unit, Door, Gate, etc.) need to be installed in proximity to each other for functional application so a User can easily present a credential, then access the secured entry point. Most systems require wiring that may involve trenching, burying conduits, setting mounting pads and posts. Installation is often the most expensive part of an Access Control System due to the time and labor involved. Contact a professional access control dealer for installation.
What are the four elements of an access control system? Faq arrow
  1. User Input Device – This could be a keypad, a card reader, a biometric scanner, a device that can accept a credential from a User to verify their identity.
  2. Entry Control Unit – A device that accepts data from the User Input Device and can allow entry to the User.
  3. Site controller – Data stored in the Site Controller is used to compare to data from the User Input Device and verify a valid credential has been received. In many applications, the Site Controller and Entry Control Unit are both contained in one product. The LiftMaster CAPXLV, for example, includes 2 User Input Devices (touch keypad and Security+ 2.0 RF Receiver), an Entry Control for 4 entry points, and a Site Controller in one product.
  4. Master Station – A centralized management device that communicates with a Site Controller to program entry credentials, schedules, users etc. and receive information on entry attempts, fault conditions, and other system events. For the LiftMaster CAPXLV, the myQ Business Smart Community platform functions as a Master Station.
