Door Access

If you require a Door access/intercom system, we have a vast knowledge and experience in being able to design and install a tailor made system that suits your needs and requirements.

Using industry leading products we are able to offer systems that enable the user to communicate and grant access to visitors from one or multiple entrances throughout the building.

Also if required we can supply and install a system that not only allows communication down to the entrances, but also internally within the building. This can be especially useful for large town houses where it’s not always possible to hear each other.

An access control point can be a door, turnstile, parking gate, elevator, or other physical barrier, where granting access can be electronically controlled. Typically, the access point is a door. An electronic access control door can contain several elements. At its most basic, there is a stand-alone electric lock. The lock is unlocked by an operator with a switch. To automate this, operator intervention is replaced by a reader. The reader could be a keypad where a code is entered, it could be a card reader, or it could be a biometric reader. Readers do not usually make an access decision, but send a card number to an access control panel that verifies the number against an access list. To monitor the door position a magnetic door switch can be used. In concept, the door switch is not unlike those on refrigerators or car doors. Generally only entry is controlled, and exit is uncontrolled. In cases where exit is also controlled, a second reader is used on the opposite side of the door. In cases where exit is not controlled, free exit, a device called a request-to-exit (REX) is used. Request-to-exit devices can be a push-button or a motion detector. When the button is pushed, or the motion detector detects motion at the door, the door alarm is temporarily ignored while the door is opened. Exiting a door without having to electrically unlock the door is called mechanical free egress. This is an important safety feature. In cases where the lock must be electrically unlocked on exit, the request-to-exit device also unlocks the door.

With the use of CCTV becoming more and more widespread, most of our systems come with the ability to integrate cameras into them. This in turn can offer functions such as snapshots to be taken when someone is at the door.

As with all systems installed and maintained by ourselves, our fully qualified team of technicians can carry out regular inspections of your system to keep it functioning at its optimum level of performance.
