NDS Ltd provide a comprehensive range of quality, safe and efficient automatic door systems.

Professionally installed and integrated into your building with multiple operating modes and options

Automatic doors not only provide a comfortable, convenient environment for all users but also ensure that doors open when required, and more importantly close after use conserving valuable energy.

Automatic doors have become a natural part of our everyday lives, people almost expect doors to open automatically as they are approached.

Automatic doors are everywhere: from bus stations to shopping centres, office blocks to council offices, banks and high street shops. In these modern times, automatic doors have become a consumer expectation.

Sliding Doors

Swing Doors

Although NDS are not affiliated with any automatic door system and can install any of main manufacturer’s operators if required we recommend the Record DFA127.

The record DFA 127 is a universal drive system for the automation of swing doors. It is characterized by sophisticated technology, compact design and especially record’s legendary smoothness of operation. Its exceptional versatility makes it suitable for a broad range of applications and widely differing requirements.

The DFA 127's universal qualities are mainly due to its electro-mechanical construction, and partly due to its modular design. When the door drive motor operates, it simultaneously tensions a spring integrated in the drive housing. The shutting movement uses energy stored in the spring, which, depending on requirements, is also motor-assisted. Even without motor assistance, thanks to ingenious mechanics, optimum power deployment is achieved in the entire door swing area. This is necessary to move the door reliably to its end position against draft resistance, for example, and also complies with the norms and standards of current safety requirements.

The record DFA 127 is available to operate doors in sizes EN4 to EN6. The different spring forces required can be quickly and precisely adjusted on the spot using the special adjustment screw.
This model can be adapted easily to provide additional functionality with no loss of integrity to suit specific requirements such as slower opening, fire resistance, inverse opening in case of power failure and other variations.

Features:

  • DIN 18 650-compliant technology, approved worldwide 
  • adjustable spring force gives it great versatility
  • adjustable to accommodate customer-specific settings
  • optimum power deployment in full swing area
  • the opening stop is integrated into the door drive system (no hazard for pedestrians to stumble over)
  • no emergency power supply required to open the door
  • the electromagnetic parking brake means additional electrical opening devices on interior doors can be dispensed with capable of complex functions
  • practically silent operation

Variations:

  • double swing doors with or without master /slave operation
  • power saving mode: adjustable opening of one or both door panels (stretcher opening)
  • integrated sequential closing control for double-leaf fire door applications
  • interlock function for two single doors installed consecutively 
  • direction-oriented opening for oncoming traffic in corridors
  • opening or closing without current
  • approved and certified fire protection
  • gerontology technology for slower opening and barrier-free access
  • Available with an optional "built in locking motor"
  • battery backup for power fail protection

Especially suitable for use in:

  • retail outlets 
  • airports 
  • administration and office buildings
  • restaurants and hotels
  • hospitals
  • residential and care homes 
  • escape route openings
  • areas requiring heat and smoke to be vented

Retro-Fit Kits

Many businesses already have automatic sliding doors, but old and tired systems can show clear signs of long term use. Their operation may be impeded by such wear and tear, potentially posing a risk to the security and safety of your business and customers. Additionally, business owners with older sliding door kits may find it increasingly difficult to source spare parts, and if they are able to, may find themselves paying over the odds for them.

For customers with existing sliding doors that require some TLC, NDS Ltd can provide a “retro-fit system” option. This entails the complete replacement of the internal electronic and mechanical components which make up the drive system (i.e. motor/gearbox, control unit etc) but retaining the existing track and cover. With a typical conversion time of around 4 hours, the “Retro-fit system” can reduce the level of disruption experienced by your customers and business during installation.
