What does a door coordinator do?

1. It ensures that doors remain locked

2. It controls the speed of door closure

3. It coordinates the closing sequence of two doors

4. It prevents doors from being opened simultaneously

The correct answer is: It coordinates the closing sequence of two doors

A door coordinator is specifically designed to manage the interaction between two doors, ensuring that they open and close in the correct sequence. This is particularly important in situations where pairs of doors might be installed, such as in a double door setup. The coordinator typically ensures that one door fully closes before the other door begins to close. This prevents damage to the doors, enhances safety, and maintains the integrity of the space. Proper sequencing is crucial in settings like hospitals or commercial buildings, where controlled access and egress are important. The other options may refer to functions related to door operation but do not accurately capture the primary role of the door coordinator. For example, while locks and closures are essential for security and functionality, they are not the central function of a door coordinator.
