FREQUENTLY ASKED QUESTIONS
Everything you need to know about Lift UPS & Battery Backup Systems.
Find answers to the most common questions about elevator UPS systems, Automatic Rescue Devices (ARD), battery backup duration, compatibility and maintenance.
What is a Lift UPS?
A Lift UPS (Uninterruptible Power Supply) provides emergency backup power during electrical outages. It enables the Automatic Rescue Device (ARD) to move the lift safely to the nearest floor and open the doors, preventing passengers from becoming trapped.
Is a Lift UPS the same as an Automatic Rescue Device (ARD)?
No. A Lift UPS supplies backup electrical power, while an Automatic Rescue Device (ARD) controls the rescue operation. Many modern systems integrate both functions to provide safe passenger evacuation during power failures.
Can an existing lift be upgraded with a UPS?
Yes. Most existing residential and commercial elevators can be retrofitted with a compatible Lift UPS and ARD after assessing the controller, motor power and electrical configuration.
How long will the battery backup last?
Backup duration depends on the UPS capacity, battery size, lift load and motor power. Most systems are designed to complete one or multiple rescue operations safely, while larger systems can provide extended backup for essential lift functions.
Which battery is better: SMF, Tubular or Lithium?
Each battery technology has its advantages. SMF batteries require minimal maintenance, tubular batteries are well suited for frequent cycling, while lithium batteries offer higher energy density, faster charging and longer service life where supported by the application.
Will it work with my lift?
VOLO POWER™ systems are compatible with many residential and commercial lift controllers after a technical assessment. Compatibility depends on the lift controller, drive, motor rating and rescue requirements.
Does the lift continue operating during a power cut?
The primary purpose of a Lift UPS is to perform a safe rescue operation. Extended operation depends on the selected UPS capacity and the building's backup power strategy.
How often should the batteries be replaced?
Battery life varies according to usage, operating temperature and battery type. Periodic inspection and capacity testing help determine the appropriate replacement interval and maintain reliable emergency operation.
Is annual maintenance required?
Yes. Regular maintenance includes battery health checks, charger inspection, electrical testing and verification of the rescue sequence to ensure dependable performance during emergencies.
Can VOLO install the system on non-VOLO lifts?
Yes. Subject to compatibility, VOLO POWER™ can be supplied and installed on many existing residential and commercial elevators from other manufacturers.
