The remote start hose and central vacuum cleaner communicate with each other permanently. If a vacuum hose is temporarily cut off or blocked, e.g. a child holds the vacuum hose closed, then this is detected by the system. The central vacuum cleaner switches itself off independently preventively.
Our central vacuum cleaner works so quietly that even the doorbell can be heard and the baby won't be woken. If you have forgotten to shut off the vacuum cleaner, the system switches itself off after an hour.
