The door System Use railway train car matured and reliable structure, the main advantages are as following：

1. The door locker system can  by mechanical locking or cut off the electric power  door system.
2. The door use aluminum frame and aluminum honeycomb structure .
3. The moving carried driving structure have the advantages of conciseness, moving smooth ,easy to install ,high reliability.  
4. Can detect minimum obstacle：30mm（wide）×60mm（high）,
5. Obstacle detect ability ：≦150N
6. Door system status display and self-diagnosis function .
7. The door system use modularization design, can be use in wide range .

• Driving mechanism working electric voltage :      DC110V（Fluctuate range：-30%～+25%） 
• Vibration condition meet TB/T 1335-96《Railway train car strength design and test assessment specification 》Requirement

Technical Specification For Electrical Part:

1. System electric power supply voltage 110VDC（-30%~+25%）、48VDC（-30%~+25%）、24VDC（-30%~+25%）
2. Car toilet door outside and in front of the passengers'  seat should be have LED display indicator.  While toilet door is locked the LED display indicator will be lighting. At this moment the toilet door 「open」 and 「close」 button electrical control will be invalid for temporarily, it means the toilet is be using .（Including toilet automatic door、accessible toilet door）.
