PURPOSE:To obtain a safe and simple full automatic window opening/closing device by providing a power distribution equipment, having top priority on a signal for emergency occurrence, on a control panel, and operating a window opening/closing device via a hydraulic unit without actuating the power distribution equipment in a normal condition. CONSTITUTION:A full automatic window opening/closing device by hydraulic control is composed of a control panel 1 and a hydraulic unit 3 arranged on a ceiling side, and an operation box 4 at a normal position. The control panel 1 is connected to a primary power source 1c, a switch box, controlling the hydraulic unit 3, and a D.C. 24D power source DC-24V, interlocking with an emergency signal or a smoke sensor, are power-distributed, and the power source is connected to a window-opening button 6 of the operation box 4. Moreover, the operation box 4 and the control panel 1 are connected with a secondary power source 2c to be made an operation circuit in a normal condition. This can operate the hydraulic unit 3 with receiving, at the time of emergency occurrence, given top priority, enabling ensuring safety. |
