The door coordinator is used on double doors when the inactive door needs to close before the active door which is equipped with or without overlapping astragal.It can prevent the active door from closing earlier than the inactive door, because the unit has an Active Door
Hold Open Lever & Inactive Door Release Trigger as shown in above Figure, this mechanism permits the active door to close and latch after the inactive door, thus both leaves can avoid collision each other.

As shown in Fig. 2 the Active Door Hold Open Lever (x) hold the active door open until the Inactive Door Release Trigger (y) is released to its retracted position by closing. The door closers must be installed on the double doors without mullion when a coordinator is used.
