Roller shutters, also called roller shutters, are types of aluminum or PVC shutters, which have been in existence for more than sixty years and were initially operated manually. They generally consist of an apron; a box that is embedded in the wall for new constructions and installed either inwards or outwards for old premises; slats and slats and they are operated by wires or chains. Thanks to modern technology, however, the roller shutters have been renovated because they have been motorized and equipped with various types of locking and remote control systems. This has resulted in what are called automatic flaps.

A motorized roller shutter

Like any device that works automatically, a roller shutter needs a motor to be able to operate without being operated by hand. This motor is normally a tubular motor consisting of two windings, a capacitor, a reducer and mechanical stops. The connection has already existing switches and is made from four cables including phase one for the rise, phase two for the descent, the neutral cable and the earth cable. It should be noted that any installation should preferably be done by professionals to avoid any accident, and it should also be noted that the power must be completely cut off at the time of the intervention. In addition, special standards developed for the supply of roller shutters require that the supply circuit in question must be either a 16A circuit-breaker if it is a 1.5mm² section; or a 20A circuit-breaker if it is a 2.5mm² section. Consequently, the roller shutter would be equipped with a wireless remote control that would save the owner time and energy since it is no longer necessary to walk around the house every morning and every night to open or close the shutters.

Comfort and safety are also better guaranteed thanks to the use of a remote controlled electric motor. In other words, different types of remote controls can be used: remote controls with a single channel that can only manage one roller shutter at a time; multichannel remote controls that, as the name suggests, can control several devices at the same time; wireless wall controls; and programmed remote controls that operate according to pre-established times or schedules.

Types of roller shutter connections

Three cases are possible when connecting automatic shutters. In the first case, the wired roller shutter must be connected, i.e. either a single stable single-pole switch or a stable PM3 switch must be used. In this way, only one roller shutter is connected to the single pole shuttle and it is finger controlled when pressed. Two positions are possible: a stable position of the button that raises or lowers the roller shutter and a central position that stops the shutter. The second case involves connecting two roller shutters to a single button on a single unstable bipolar switch. Indeed, the two poles of the inverter allow the two roller shutter motors to be connected and operated simultaneously. As soon as you stop pressing it down, the roller shutters stop quickly.  Finally, in the last case, a roller shutter must be connected to two or more control points; this requires the use of a remote switch, a key box and push buttons. The remote switch sends an electrical pulse to the motor each time one of the push buttons is pressed.

To go even further, there are currently connected roller shutters that are at the cutting edge of technology and through which operation is via the Internet. Therefore, all computer devices that can be connected to the Internet such as the computer, smartphone or tablet can remotely control the closing or opening of the roller shutters thanks to a server and a box (or control unit) that transmit the control information and automatically program the shutters. Apart from that, there are also solar roller shutters that work by capturing solar energy through a photovoltaic panel and that are located on the trunk of the shutters.
