Double door system (1) comprising an understriking door leaf (2), an overstriking door leaf (3), a first door operator (11) adapted to move the understriking door leaf (2) between an open and a closed position, a second door operator (12) adapted to move the overstriking door leaf (3) between an open and a closed position, a mechanical brake arrangement (100) and an electric coordination system (90),
- wherein the understriking door leaf (2) should be closed before the overstriking door leaf (3) to close the double door, and wherein the mechanical brake arrangement (100) comprises a braking member (101, 102) arranged to brake the movement of the overstriking door leaf (3) and a first controlling member (103) which is mechanically operated,
- wherein the first controlling member (103) is arranged to control the braking of the braking member (101, 102) in relation to the position of the understriking door leaf (2),
- wherein the second door operator (12) comprises a second motor (22) arranged to drive the overstriking door leaf (3) between the opened and closed position, and
- wherein the electric coordination system (90) further comprises an electric coordination controller (91) operatively connected to the second motor (22), the electric coordination controller (91) being configured to control the second motor (22) to brake the movement of the overstriking door leaf (3) based on the position of the understriking door leaf (2), the electric coordination system (90) being electrically operated.
Method for operating a double door system (1), the double door system (1) comprising an understriking door leaf (2), an overstriking door leaf (3), a first door operator (11) adapted to move the understriking door leaf (2) between an open and a closed position, a second door operator (12) adapted to move the overstriking door leaf (3) between an open and a closed position, a mechanical brake arrangement (100) and an electric coordination system (90), wherein the understriking door leaf (2) should be closed before the overstriking door leaf (3) to close the double door, and wherein the mechanical brake arrangement (100) comprises a braking member (101, 102) arranged to brake the movement of the overstriking door leaf (3) and a first controlling member (103) which is mechanically operated, wherein the first controlling member (103) is arranged to control the braking of the braking member (101, 102) in relation to the position of the understriking door leaf (2),
- wherein the second door operator (12) comprises a second motor (22) arranged to drive the overstriking door leaf (3) between the opened and closed position of the overstriking door leaf, and
- wherein the electric coordination system (90) further comprises an electric coordination controller (91) operatively connected to the second motor (22), the electric coordination system being electrically operated, the method comprising:
- controlling the second motor (22) to brake the movement of the overstriking door leaf (3) based on the position of the understriking door leaf (2).
