Modern elevators don’t rely on only one power source to maintain operations. They generally use battery or generator backup power so that they can continue operating in case of a power outage or other emergency.
Learn why elevator battery backup is critical. Then discover another essential safety feature in modern elevators: two-way video elevator monitoring services from ELEVATE Monitoring.
How Elevators Operate on a Normal Power Supply
Grasping the importance of elevator battery backup starts with understanding how elevators work. These machines rely on a combination of both electrical and mechanical systems.
A system of motors, cables, and pulleys safely transports the car between floors upon the user’s request. The motor relies on electricity to operate, meaning that during a power outage, the elevator would be inoperable without some sort of power supply.
The Importance of Elevator Backup Battery Power
Elevators often need to continue operating in the case of a power outage. This is especially true for in-progress rides; the elevator must have backup power to safely arrive at the next-closest floor and allow passengers to exit.
This is why modern elevators rely on some sort of backup power supply, generally at least one of the following:
- Generators are a common source of backup power, running on natural gas, diesel, or propane. Many commercial buildings have generators that automatically turn on when the main power supply fails, enabling critical systems like the elevator, emergency lights, and the HVAC system to continue working.
- Batteries are often a secondary backup power supply for elevators. Elevator battery backup systems allow the elevator to continue operating for a limited time when the main power supply fails. This ensures that the elevator can continue functioning and safely complete the ride when a power outage occurs.
Smaller commercial buildings or residences might use battery backup in place of generators. These systems still provide emergency power for elevators but are generally less complex than large generator systems. Generators also need to be ventilated correctly to prevent the buildup of carbon monoxide in the building.
Best Practices for Maintaining Emergency Power for Elevators
Battery backup systems and other forms of backup power won’t do you much good if they don’t work when you need them to. Generally, you should test your backup power system at least once per month and schedule a full professional inspection at least annually to ensure that these systems are performing as expected.
An inspection can also tell you whether it is time to replace your elevator battery backups. Generally, these batteries need to be replaced after they have been in service for two or three years, though some may last longer.
Enhance Your Elevator Power Outage Safety With ELEVATE Monitoring
As you prepare for a power outage, consider how occupants can seek help during a sudden elevator outage or emergency. ELEVATE Monitoring offers two-way video monitoring systems so that occupants can see and speak with a trained operator in real time and receive the emergency assistance they need.
