Highway key?
Hello, I've often wondered while driving on the highway whether all the emergency exit doors have the same key so the alarm doesn't go off…basically, whether there's a general model for all of Germany, or whether it varies by state. It's been a mystery to me for years. Best regards
These e.g.
No alarm is triggered. It’s different in Tunnels. They’re also camera surveillance.
They’re not locked.
Well, actually, they’re not locked, but the key doesn’t trigger the alarm…
No, door contacts do.
They’re always open. May not be closed
It was stupid that the keys didn’t mean the alarm was…
I can’t imagine a sharp-connected alarm system installed in a noise protection wall…
These are devices that trigger an arlarm when the door is opened. Sowa doesn’t exist on highways
But you can find them everywhere under “doorkeepers”
