Architectural Specifications:
1. Operation
The automatic door operator is to be fully electronic operator, housed in a fully anodised aluminum transom section.
2. Prerequisites,
The Automatic Door Operator is to be a fully electric operator, housed in an extruded aluminum low profile transom section
A) The equipment will incorporate electronic computerized DC Motor with built in optical sensor for precise movement, high torque for a maintenance free life.
B) 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
C) 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; Battery back up to allow the door to open) for under power failure.
D) 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.
E) Safety feature: Moving doors will automatically reverse when traveling in either direction, if obstructed, sensitivity setting to be programmable.
F) During a power failure or emergency the Failsafe device will fully open the doors. The failsecure mode will close and secure the doors until power is restored
Actuation
Microwave directional sensors
Passive infra-red sensors
Remote control transmitters
Motor: The motor is brushless 24 volt DC with in-built optical sensor for precise movement, operation is silent and maintenance free, delivering high torque and high operating speeds.
Controller
The intelliget controller unit can be programmed for connection to any security/alarm systems, is self monitoring and calibrating, has memory for all data on door stoke and brake positions.
UPS
The operator has built-in uninterrupted power supply (Battery back up) operation and security during power failure.
Belt Drive
Drive is by way of toothed belt, which is reinforced with fiberglass tensile members, and has nylon facing surface for tooth protection on the pulleys. This combination produces silent accurate operation.
Tracking The track is self-cleaning duel linear. The upper track is made of harder stronger alloy 6351T6, and can be replaced without moving the transom. The wheel trolley is fitted with anti-rise wheels, resulting in very firmly fitted doors with operation free of any racking.
Locking
Electromechanical Locking: An electric lock option is available to give total security and can be adapted where manual locking cannot be achieved, i. e. Frameless toughened Glass doors. Lock is the microprocessor controlled electric locking system. The microprocessor monitors all aspects of the lock functions. E. G. To ensure the door is fully closed when the lock is 100% engaged. Terminal outputs are available to signal to security system both door positions and lock status.
