  • FiOS Digital Voice and Home Security Systems If you have a home security system that uses a jack in your house, FiOS® Digital Voice uses those same jacks.

    In the case of an electrical outage, your FiOS Digital Voice service that is provisioned through your normal telephone jacks will continue to operate on ONT battery* power for up to 8 hours. If electricity has not returned by that time, it will not be possible to make or receive calls, including emergency calls to 911 and your alarm system will not be able to call out. Verizon strongly recommends you check with your alarm provider to ensure compatibility.

    *Important Note The Verizon supplied battery is designed specifically for use with the Verizon FiOS Network. Use of a battery other than a 12-Volt 7.2 Ah SLA Sealed Lead Acid battery is not recommended since other battery types may impact the performance of your FiOS services. Verizon is not responsible for damages which result from use of an improper battery.
