Previously, the loss of a standard key could create quite a risk to security and rectifying the situation could be costly.

With access control systems, if you lose a key fob, token or card, the specific item can be deleted from the system creating no compromise to security.

Even specific parts of buildings can be controlled, limiting who can enter at different times of the day or night.


At Barrs we can supply and install a bespoke stand alone or PC Based proximity tag system giving you full control of who can enter the building and at what time of day and night.


Our trained engineers will first listen to your need's and then design the system to meet your need's, they will explain the pro's and con's of the various locking solutions as well as recommend the type of reader be it anti vandal for high risk environments or pc based for large institutions to small standalone readers for small installations, or a mixture of both.



This is a Paxton Proximity metal reader:

The PROXIMITY metal reader is for use with Switch2 and Net2 systems. It is contained in a cast metal housing with a satin chrome finish. The result is a smart, rugged reader. As the reader is already housed in metal, its operation is affected less by fitting within close proximity to other metal objects. This makes it suitable for installation onto metal door frames, car park reader posts etc.


A token is read by holding it within close proximity to the reader. Once a token has been read the control unit looks up the access permissions of that user. Access is then granted or denied as appropriate. If access is granted the green LED flashes, if access is denied the red LED flashes.

Paxton Switch 2 Controller

Switch2 is a single door control unit. The Switch 2 control unit stores the access permissions of the user and is mounted within the building. This makes the system suitable for high security applications. 

Switch2 can be used with PROXIMITY, CARDLOCK or TOUCHLOCK readers. Switch2 can be installed to many doors over a site, all using the same tokens. Two readers can be connected to a single unit to give read in and read out access control. 


The operation of Switch2 depends on the mode.

PROXIMITY and CARDLOCK. User tokens are valid and ready for use once installation is complete. Every user token is supplied with a corresponding shadow card. As user tokens are issued, the name of the user is marked on the shadow card. If a user is to be barred, or a user token is lost, the shadow card marked with the users' name is presented to all readers on site. This simple action invalidates the user token. Another user token may be issued for that user.

Additional features can be programmed using the PROXIMITY or CARDLOCK function card pack. These features include zoning which allows you to limit access by token colour.

TOUCHLOCK If a valid code is entered access is granted. Codes are changed via the keypad using the master code. 

PROXIMITY KP keypad. Choose card + code, card + PIN, card only or code only.

Paxton Net2 Controller


Net2 is a networked access control system. A networked system gives the advantages of central control, event reporting and flexible control over users' access. Each control unit is part of a network but can run independently making its own decisions and remembering events.

The control unit has FLASH memory which means that firmware can be upgraded from the PC. This is the key to making the system future proof.

Control units are sold as a PCB only, within a plastic housing or mounted within a 2A boxed metal/plastic mains monitored backup power supply.

Any changes made at the PC are immediately communicated and stored at the control unit. When a user presents their token to the reader, the control unit identifies them and permits or denies access as appropriate.

These are examples of Proximity systems we can supply and fit, we can also service an existing system and carry out repairs/routine maintenance as required.
