Information regarding Backup Power Battery Options
Your Fiber-Optic Voice service requires electricity in order to work. In the event of a power outage, you won’t be able to make or receive calls, including calls to 911, unless you use an alternative like a cell phone. If you have an alarm system it may not be able to contact its central monitoring station in the event of a power outage. Depending on the Verizon equipment installed at your home, backup power may be provided by a Battery Backup Unit (BBU) that uses a 12-volt battery or a PowerReserve device that uses 12 D-cell batteries that you provide. Please click on the picture below that matches the equipment installed in your home.

How do I order, replace and dispose of the battery for my Battery Backup Unit (BBU)
The Optical Network Terminal (ONT) includes a Battery Back Unit (BBU) option, which you may utilize by maintaining an active 12-volt battery in the BBU. With a fully-charged battery, the BBU will provide backup power for your basic Fiber-Optic voice services, including Emergency 911 dialing, for up to 8 hours in the event of a commercial power failure. You are responsible for purchasing and/or replacing the battery in the BBU. Much like you would need to replace the batteries in a smoke detector or flashlight from time to time, periodically the battery must be replaced.
The BBU is installed at your location in an area where it can be easily monitored. The BBU is connected directly to the ONT to provide backup power if it's needed. In addition, the BBU contains a series of indicator lights that tell you whether your service is being powered by your location's electricity or the battery if one is installed. The BBU also indicates when the 12-volt battery needs to be replaced.

BBU Audible Alarms
If there is a problem with your BBU, an alarm will sound for 2 seconds and be silent for 58 seconds. This will be repeated until you press the Alarm Silence button. Once you do, be sure to check the lights on the BBU to find the issue (see above). Below are the most common reasons for the alarm to sound:
Low Battery – alarm is silenced after electrical power returns, the battery is fully discharged or removed from the BBU
Replace Battery – alarm is silenced when the battery is removed
