3 or 4 wings revolving door

Description

KA**3 KA**3 3/*-wing revolving door not only elegant but also economical and practical. Anti-strike+ anti-squeeze+ instant-reaction safety function. Function: Safety functions 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 enabling push-and-go. 3. Anti-squeeze When the anti-squeeze sensor 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 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 to enable the door revolving at low speed to facilitate the disabled. Operation features 1. Continuous working modes Door keep revolving at low speed if no pedestrians, door revolves at normal speed if pedestrians are detected by infrared sensor and the mode will keep on until no pedestrians. Specially designed for large traffic flow. 2. Go/Stop working mode 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 down-lights can be remote controlled. Electronical & mechanical features 1. Advanced control system Apply PLC and A/C inverter control system to achieve steady operation with more functions and prolonged life. 2. Two-stage brake system Apply “Belt + Gear”- two stage brake system to make full use of their complementary advantage: steady and quiet transmits of belt and bigger torque transmits of gear. 3. Regular voltage system Apply 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.
