The PowerReserve device is used with an Optical Network Terminal (ONT) configured with a Power Adaptor. With 12 fresh D-Cell or “flashlight” batteries, the PowerReserve provides at least 24 hours of backup power for basic voice service, including 911 dialing, in the event of a power outage.


Note: The Verizon technician will be able to tell you during installation if your services of  your equipment is compatible with PowerReserve.


NOTE : If you use Verizon’s fiber optic voice service to connect your alarm or fire system to a central monitoring station, you have the option to receive email and/or text message notifications when (1) commercial power to your equipment is lost, and (2) when your backup power has exhausted. Notification of the exhaustion of backup power requires a Verizon-provided Battery Backup Unit or Power Reserve.
