The difference between sequencer and door closer

The difference between sequencers and door closers lies in their functions, usage scenarios and installation methods.

1. Function: The main function of sequencer is to control the opening sequence of doors. For example, in hotels, shopping malls and other places, it is necessary to ensure that multiple doors are opened one by one in a certain order to avoid congestion or security risks caused by simultaneous opening. The main function of the door closer is to control the closed state of the door, ensure that the door can be closed automatically, and play a safe and energy-saving role.

2. Usage scene: The sequencer is usually used for the entrance and exit of public places, such as hotel lobbies, shopping malls, cinemas and so on. It is necessary to ensure that multiple doors are closed in a preset order to ensure safety and smoothness. Door closers are more suitable for private houses, offices and other places, which can avoid forgetting to close the door and prevent outsiders from entering private space.

3. Installation mode: The installation mode of sequencer and door closer is slightly different. Sequencer generally needs to be installed on the top or side of the door, which requires professional installation and debugging. The door closer can be installed by itself, just fixed on the door frame.
