ᐅ Second Escape Route Problem Due to Electric Roller Shutters

Hello.
We have a problem because we have electric roller shutters throughout the ground floor and first floor. Our architect said that a second escape route must always be ensured. In the event of a fire, the electrical system could fail, and we might not be able to use the second escape route from the first floor window above the garage. The building authority / planning permission office is said to be strict in such cases. The architect recommends a manual crank. Do you possibly have a better idea? A manual crank doesn’t look very appealing…

This is not Hollywood, where it takes 10 seconds from smoke detector activation to full fire, and after 15 seconds the heat exchangers explode...
It takes about 5 minutes between "cigarette falls on sofa" and "living room reaches 800 degrees Celsius (1472°F), windows shatter, and the air starts to burn."

Are there also any good demonstration videos on YouTube?

In the meantime, you would have suffocated from carbon monoxide.

That's correct. Usually, the neighbors are awakened by the breaking of the windows; the actual occupants no longer are....

I once asked a fire chief.
It is correct that roller shutters must be able to be opened manually, either with a crank or by simply prying them open.

The question is not how intense the fire must be to cause a power outage. Once the fire is reported, the utility company is immediately alerted and the electricity is shut off. By the time the fire department arrives, the house will already be without power.

I am now checking whether we have such roller shutters; we do not have cranks.

I can confirm Haydee’s post. This was already discussed during my architect meeting, and the escape window in the bathroom was planned from the start with a crank handle. It doesn’t cause any disturbance there at all.
