NGF System Frameless Doors

Frameless Door Operator – NGF System

The introduction of the next generation series of automatic door operators is a major advancement in automatic doors technology in the Australian and global automatic door markets.

NGF Specifications



The Automatic Door Operator is to be a fully electric operator, housed in an extruded aluminium low profile transom section (Height 132mm x Width 155mm) the unit shall be Australian made by an Australian owned company, must comply to AS4085-1992, have a class 3 rating, to suit bi-parting or single sliding doors.

  1. The equipment will incorporate electronic computerized DC Motor with a built-in optical sensor for precise movement, high torque for a maintenance-free life.
  2. The pelmet shall incorporate an integrated and interlocking hinge for secure closure and maximum cover. The design shall enable the operator to be fitted flush to the ceiling when required, while the pelmet may be opened fully or removed for access.
  3. The multifunctional microprocessor control unit shall feature the following:
    • Self-calibrating and programmable modes
    • Fully compensates door weight and friction, therefore, delivering the optimum force for efficient operation
    • Independent circuits for pressing closed at the end of the closing stroke
    • Provision for full interfacing with all types of building security/alarm systems
    • Open speed control
    • Closing speed control
    • Brake control: preventing the doors from slamming shut
    • End position-damping control for the accurate slow down of door movement
    • Built-in UPS (uninterrupted power supply) for the continued operation of the door under power failure.
    • The option of solar power provision to be included.
  4. The tracking system is to be dual linear track designed for accuracy and long service life fitted with anti rise wheels with no possibility of doors disengaging off tracks. The upper track shall be made of harder and stronger alloy and be replaceable. Each track wheel is fitted with track wipers to maintain clean contact.
  5. Safety feature: Moving doors will automatically reverse when travelling in either direction if obstructed, sensitivity setting to be programmable.
  6. During a power failure or emergency, the fail-safe device will fully open the doors. The fail-secure mode will close and secure the doors until power is restored.
  7. Provision for climate control shall be available. Door opening can be restricted from 50% of normal door operation during high winds or low traffic situations.
  8. Dual sets of sun-resistant P.E. light cells flush-mounted in the door jambs will prevent doors from closing if the threshold area is obstructed. Fitting of P.E. light cells will be at 150mm and 600mm from finished floor level.
  9. Door drive shall be by way of toothed belt reinforced with fibreglass tensile members, will incorporate nylon facing surface for pulley tooth protection, for silent and service-free operation.


The following functions can be selected through your wall-mounted key switch or options board:

  • Auto: Doors are operated automatically via the movement sensors.
  • Open: Doors maintained in open position continuously.
  • Exit: Doors remain closed activated only by exiting traffic.
  • Lock: Doors remain closed and locked where optional electric lock function has been installed. Exit by way of emergency exit button.
Multi Functional Mode Pad
The automatic door is controlled by a six-position digital keypad with Lock, Auto, Exit, Hold Open, Climate and Off Modes.
Pelmet Hinge
The ADIS pelmet design features a unique interlocking hinge to provide secure closure and maximum cover even when mounted hard up against the ceiling.
High Security Locking
An electric lock option is available to give total security and can be adapted where manual locking can not be achieved, i.e. frameless toughened glass doors. Lock type is the microprocessor-controlled electric locking system. The microprocessor monitors all aspects of the locks functions; e.g. To ensure the door is fully closed when the lock is 100% engaged. Terminal outputs are available to signal to security systems both door position and lock status. The microprocessor is also self-diagnosing.
Activation shall be one of the following:
  • Microwave sensors
  • Flush-mounted sensors
  • Passive infrared sensors
  • Fine line sensors
  • Induction loops
  • Remote control transmitter
  • Key card system.
  • Advantages
  • Australian made
  • Slimline Modern Design
  • Designed for new standards
  • Concealed glass top rail
  • High-Security electric Locking
  • No Exposed Wiring
  • Energy Efficient
  • Quiet Operation
    The tracking system is dual linear, which is designed for high security and long life service. The carriage assemblies are fitted with unique track wheels that eliminate the possibility of the doors disengagement from the track.
