The unique function of Sunbeam Speedy Roller Shutter!!!
“In Emergency power-outage situations where the door is inoperable, you can still manually open the shutter no matter if you are on the inside or on the outside. From the inside, there is a control box close to the shutter where you can set the transmission gears to neutral, allowing you to manually open or close the shutter. If you are locked outside, you can use your remote control to instruct the control box (on the inside) to set the transmission gears to neutral – since both remote control and control box have battery power, this procedure still works during a power outage”.
