Under normal circumstances, when can the emergency equipment for power outage in residential corridors be started?

When the community loses power.

The emergency equipment for power failure in the corridor of the residential area will start when the residential area is powered off, and sometimes it will start when it is detected.

If there is a power outage in the community and there is no power outage in other surrounding communities, then the owner can contact the community property to verify whether the power facilities in the community are maintained by the property or the power sector.
