1. A double door system comprising an understriking door leaf, an overstriking door leaf, a first door operator adapted to move the understriking door leaf between an open and a closed position, a second door operator adapted to move the overstriking door leaf between an open and a closed position, a mechanical brake arrangement and an electric coordination system,
wherein the understriking door leaf is closed before the overstriking door leaf to close the double door,
wherein the mechanical brake arrangement comprises a braking member arranged to brake the movement of the overstriking door leaf and a first controlling member which is mechanically operated,
wherein the first controlling member is arranged to control the braking of the braking member in relation to the position of the understriking door leaf,
wherein the second door operator comprises a second motor arranged to drive the overstriking door leaf between the opened and closed position,
wherein the electric coordination system comprises an electric coordination controller operatively connected to the second motor, the electric coordination controller being configured to control the second motor to brake the movement of the overstriking door leaf based on the position of the understriking door leaf, the electric coordination system being electrically operated,
wherein the first door operator comprises a first motor arranged to drive the understriking door leaf between the open and closed position and the electric coordination controller is operatively connected to the first motor to control the operation of said first motor,
wherein the first controlling member and the second controlling member are arranged to put the braking member in a mechanical braking state when the understriking door leaf is in an opened condition and the overstriking door leaf is in a second opened state, which second opened state corresponds to a position of the overstriking door leaf having an angle (α) in relation to a closed position of the overstriking door leaf that is equal to or smaller than a first predetermined angle (αm),
wherein the first controlling member is arranged to put the braking member in a non-braking state when the understriking door leaf is in a closed condition, and wherein the second controlling member is arranged to put the braking member in the non-braking state when the overstriking door leaf is in a first opened state, which first opened state corresponds to a position of the overstriking door leaf having an angle (α) in relation to a closed position of the overstriking door leaf that is larger than the first predetermined angle (αm),
wherein the electric coordination system is configured to operate in a service check mode wherein the electric coordination controller is configured to instruct the first motor and the second motor to drive the understriking door leaf to the opened condition of the understriking door leaf and the overstriking door leaf to the first opened state of the overstriking door leaf, said first opened state of the overstriking door leaf corresponding to a position wherein the overstriking door leaf has an angle (α) in relation to the closed position of the overstriking door leaf that is larger than the first predetermined angle (αm), wherein the electric coordination controller in response to the understriking door leaf and the overstriking door leaf being in the opened condition of the understriking door leaf and the first opened state of the overstriking door leaf, respectively, is configured to instruct the second motor to drive the second door operator to move the overstriking door leaf in a closing direction.
