ABSTRACT This invention relates to apparatus for operating a roller shutter system of the type comprising a flexible or segmented shutter which is wound upon a roller and an operating strip wound about the roller (or a reel attached thereto) for raising and lowering the shutter. The invention provides a compact self-contained drive apparatus which can easily be applied to existing manually operated systems or incorporated in new systems during manufacture. The apparatus comprises a chassis having mounted thereon a counter-reel for the operating strap of the roller shutter; a low-power electric motor having integral high stepdown-ratio reduction gears for rotatably driving the counter-reel; switch means for activating the motor by selectively connecting it to a power supply; a central control unit and timer for the motor; and a control and display panel for the central control unit and timer facing outwardly from said chassis to permit access to said panel by an operator when said apparatus is installed in a wall opening or the like.
