NGF System – Frameless Doors

FEATURES

• Slim line Modern Design
• Australian Made
• Designed for new standards
• Concealed glass top rail
• High Security electric Locking
• No Exposed Wiring
• Energy Efficient

Quiet Operation

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 eliminates the possibility of the doors disengagement from the track.

Advanced Technology

ADIS utilizes the latest in digital microprocessor technology, giving the control unit multiple programmable modes including: – provision to interface with builidng security system, monitoring the doors position status, built-in UPS. The microprocessor operating parameters can be adjusted to accommodate various climatic conditions and specific site requirements in relation to speed, braking etc. Safety is a priority: The ADIS microprocessor will automatically reverse operation in both opening and closing should the doors be obstructed. Photo electric safety light cells mounted to focus across the doorway with halt operation immediately upon beam interruption.

Operation

The Automatic Door Operator is to be a fully electric operator, housed in an extruded aluminum 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 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 accurate slow down of door movement
   • Built-in UPS (uninterrupted power supply) for continued operation of door under power failure.
   • 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 traveling 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 fiberglass tensile members, will incorporate nylon facing surface for pulley tooth protection, for silent and service free operation.
