3 wings revolving door

Description

3 wings revolving door: Not only elegant but also economical and practical. anti-strike+anti-squeeze+instant reaction safety function, Project in T3 of Safety: 1. Lock up: The door can find locking-up position automatically and lock up manually. 2. Fire alarm: KA**3 automatic door has pre-fixed a *-chip signal wire as the fire-alarming control port. When there is fire alarm, The panic breakout comes into operation automatically enable to push-and-go. 3. Anti-squeeze: When the anti-squeeze sensor on the mullion at opening to be touched, The door will stop immediately. When the sensor at entrance detects pedestrian, The door will stop immediately. 4. Anti-strike: When the anti-strike sensor at the wings bottom to be touched, The door will stop immediately. 5. Instant-reaction: When the resistance to the revolving wing is bigger than the preset parameter(adjustable), The door will stop immediately. 6. Handicap: Press the button enable the door to revolve at low speed to facilitate the disabled. Operation: 1. Continuous working modes: The door keep revolving at low speed if no pedestrians, The door revolves at normal speed if pedestrians are detected by infrared sensor and the mode will keep on until no pedestrians. This mode is quite suitable for large traffic flow. 2. Go/Stop working mode: The door stop if no pedestrians(3 and 4 wings series have different stop position), The door revolves at normal speed if pedestrians are detected by infrared sensor and the mode will keep on until no pedestrians. This mode is energy saving and offers better insulation. 3. Remote control function: All downlights can be remote controlled. Electronical & mechanical features 1. Advanced control system: KA**3 applies the PLC and A/C inverter control system, which improves its steady operation with more functions and prolonged life. 2. Two-stage brake system: KA**3 driving system applies Belt + Gear two-stage brake system, which makes full use of their complementary advantage: steady and quiet transmits of belt and bigger torque transmits of gear. 3. Regular voltage system: KA**3 applies unique and professional regular power system that expands voltage range and improves its stability and safety. 4. Airproof brush system: Based on static balance theory, KA**3 applies airproof and dustproof brush.
