Battery Backup Unit

If you have a backup battery, and do not have voice service through Verizon, or if you do not need voice service during a power outage, you can disconnect the battery.

You are responsible for monitoring and maintaining your backup battery. Battery age, usage and temperature will impact battery life and performance so reducing the amount of time the batteries remain stored and unused is recommended.

Only 12-volt 7.2Ah sealed lead acid batteries should be used in the BBU. Batteries should be purchased just prior to replacement as 12-volt batteries may not maintain their shelf life when stored.

If you use Verizon’s voice service with our backup power to connect a fire alarm to a central monitoring station, we will notify you during a loss of commercial power if you provide us an email or mobile number when placing your order.

An alarm will sound once a minute to alert you if the 12 volt battery in the battery backup unit (BBU) is not fully charged or has been drained completely. Your battery unit may look different from the one in the illustration below. The steps to mute battery beeping are the same for all battery backup units.

How to stop the beeping:

• Locate your battery backup unit (BBU)
• Press and hold the Alarm silence button for 10 seconds.
• You either hear a loud beep or the lights will flash on and off. If you did not get a beep or flashing lights, press and hold the Alarm silence button and the emergency use button together for 10 seconds.
• The above steps will reboot your BBU and clear the alarm.

Good to know: The reboot will temporarily disrupt all your Fios services and take between 3 to 5 minutes to complete.

Good to know: Only 12-volt 7.2Ah sealed lead acid batteries should be used in the battery backup unit. Batteries should be purchased just prior to replacement as 12-volt batteries may not maintain their shelf life when stored.
