Q:How do I open an electric roller shutter door when there is a power cut?
A standard electric roller garage door will have a manual override system as standard on the INSIDE only, meaning you can open and close your roller door by using a winding handle system, which inserts or hooks onto an eye, which is part of the electric motor. You then simply wind up or down as required until the power comes back on or you sort out the problem.
Some roller doors have a spring balancing method along with their motor drive, like the Hormann Rollmatic, so the emergency override is even simpler. You release the electric motor drive from the door by pulling a release rope internally and then you can lift up and push down the door as it is balanced with the springs. Again, just lock the motor back in once sorted.
If you do not have another entrance to your garage to access the internal manual override then you will need an emergency 'external' override system adding to your door. This is a knuckle jointed system whivh takes the internal override and extends its functionality to the outside at roughly waist level. Access to the system is protected by a lockable steel plate and when you remove this plate you can insert a winding handle from the outside and take the door up or down as required.
