1.When opening the door, to wait for the building personnel issued open signal, that is, to hear the "click" sound again, do not force the door before.

 

2.Door closers should not be opened for a long time. Too long opening time is likely to cause oil leakage of door closers, making them unable to work normally.

 

3.Take your own key, do not lend to other people, do not let people do not know when entering the door, put up small advertising people and small business hawkers to enter.

 

4.Do not open the door door for a long time to the maximum, do not use bricks, sticks and other hard objects pad in the door hinge under the corner and the threshold, so easy to damage the door, especially when there is a strong wind, extremely easy to cause damage to the door.

 

5.Once the door cannot be opened, do not smash, kick, give me peace, and then reopen the whole system after the original state.

 

6.With the key to open the door, must not hand tight door handle, hand turn the key, because the electronic system in the process of opening the door will send electrical signals, transmitted to the mechanical part, because the mechanical part of the force to open the lock tongue is very small, if the pull tight handle, can not open, make the lock tongue can not retractable, door can not open.
