Done! I've added the schematics to the project.
Indeed, for this kind of project you need some battery backup.
I bought a really nice power source that has a battery built-in, like a small UPS.
It has 800mA, by my calculations it's going to hold for about 16h.
In the case of complete power failure, the door will stay locked and you can use your key as you normally do.
That's why I went with the electric strike over the electromagnetic lock.
