Household elevator typically handle power outages through several built-in safety features designed to ensure passenger safety. Here's how they usually operate during a power loss:

Battery Backup System:
Many home elevators come with a battery backup system that activates during a power outage. The battery allows the elevator to descend to the nearest floor so passengers can exit safely. While the backup system enables downward movement, it usually doesn't support upward travel.

Automatic Emergency Lowering:
In some elevators, if a power outage occurs while the elevator is in use, the system will automatically lower the elevator to the nearest floor using a backup battery or gravity-fed system.

Manual Lowering Mechanism:
Some models have a manual lowering feature that can be operated by a trained person to bring the elevator safely to a lower level in case of power failure.

Emergency Lighting:
Elevators typically have emergency lighting powered by the backup battery, which provides light inside the cabin during the outage, preventing passengers from being left in complete darkness.

Audible Alarms or Intercom Systems:
Elevators often include an alarm or emergency communication system. This feature allows passengers to signal for help or communicate with someone outside the elevator in the event of an emergency.

Resuming Normal Operation:
After the power is restored, the elevator can typically resume normal function. However, in some cases, a reset or service may be needed, depending on the model and the elevator’s settings.

These safety measures ensure that household elevators remain secure even during unexpected power outages.
