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…

And if the house is on fire and filled with smoke, am I supposed to connect the crank and operate it manually? Strange logic from the fire department.
It wasn’t an issue in our previous house either – everything was electric. Honestly, I would be more concerned about the smoke than the lack of power.
In theory, you can get out quickly here. It’s a different story during a power outage. I should talk to my two fire chiefs about this.

Benutzer191 Jul 2019 15:12This is not a definitive solution, I just wanted to mention that I have configured my system so that if the smoke detectors go off, all the roller shutters will open to ensure a quick exit everywhere. I strongly assume that there will still be power at that time.
Have you ever looked closely at the slats of roller shutters? The spring breaks if you handle them the wrong way. We have aluminum roller shutters, and they don't hold up well... in winter, the motor was torn apart because they were frozen.
What I mean is, an average adult can easily break these things. Others not only have the shutters as obstacles but also the window sill or fall protection to deal with.
Normally, smoke detectors should go off before everything fills with smoke, so I can either take the one!! staircase to the exit or close the room door and signal for help at the window...
We're not in Hollywood, where it takes 10 seconds from the smoke detector going off to a full fire, and after 15 seconds the heat exchangers explode...

There is also a difference between self-rescue and external rescue (referred to outside of building regulations as "escape route" and "rescue route").
The second rescue route is usually not designed for self-rescue (e.g., jumping from the attic), but for external rescue. It is intended only for someone from outside to access and provide assistance.

This isn’t a complete solution, but I just want to mention that I have set up my system so that if the smoke detectors go off, all the shutters open automatically to allow a quick escape everywhere. I strongly assume that there is still power at that moment. That’s probably the case with every bus system. HOWEVER, fires very often start from electrical devices, which can already cause a power outage. If a photovoltaic system with battery storage is involved, it gets even more complicated. I think the idea of connecting the motor for the second emergency exit to the UPS (with a separate cable!) is not a bad idea.
Yes, if you have the opportunity, it is definitely a sensible idea.
I had misunderstood your previous post regarding this.
It is interesting how some people here overestimate their ability to react in case of fire.
In most cases, you never experience such an event or only once in your lifetime. A thousand thoughts go through your mind, and a single breath of smoke can make you collapse.
The escape route is meant for rescue by others, as mentioned. No one is supposed to jump out like a ninja. The smoke entering (chimney effect and what has been described) is the lesser evil. If there is smoke in the stairwell, you have zero chance of getting out on your own. Making yourself visible for rescue by others is the best approach.
