Get battery backup info for apartments or condos

Live in an apartment or a multi-unit building? Find out what you need to know about battery backup equipment.

What to know

If you live in an apartment or condo community, you will have different requirements for your battery backup depending on your equipment. Here’s how to find what you need.

Review this building and community PDF

If your complex:

  • Is on the list, you can’t get 24-hour backup. Review details on this article for more info.
  • Isn’t on the list, check your equipment.

FYI: This list was last updated in 2020 and is no longer being maintained. Ask your building manager if they have updated their equipment since then, if you want 24-hour backup.

If your building is on the list

In case of a power outage, your phone service including 911 service will cease to function. We strongly recommend that you have other means of reaching 911, such as from a mobile phone, for use during power outages that exceed 4 to 8 hours.

If your apartment complex is connected by AT&T Fiber, you can buy a PSI battery and charger that will power your Wi-Fi gateway so you can use your phone for up to eight hours or as long as your building’s equipment is operational.

More info

Buildings on the PDF list use a certain kind of AT&T network equipment to provide our phone service to occupants. This equipment requires substantial power and can operate on batteries for four to eight hours during power outages.

We contacted your property manager or landlord to install equipment, at our expense, that’ll provide backup power for 24 hours. Your property manager or landlord hasn’t accepted our offer yet or we may be in the process of installing the equipment.

Important tips

  • Make sure you know how to get to your ONT if necessary. If you can’t locate it, contact your building manager.
  • Check the battery regularly to make sure it’s charged.
  • Replace your battery when necessary. For many backup units, audible alerts or a change in status lights indicate when the battery needs to be replaced.
