Protect your household while enjoying Xfinity Voice service.
Compatibility with emergency alert services
Xfinity Voice service is compatible with personal emergency alert response systems provided by Philips Lifeline and Linear LLC. Xfinity Voice service doesn’t guarantee compatibility with other systems.
To check compatibility, we recommend that you contact the agency that provided you with the personal emergency alert response system prior to installation of your Xfinity Voice service.
When to contact your alarm or device company
For your home alarm:
- Contact your alarm company before your Xfinity Voice installation.
- Provide the date and time of your installation so the alarm company can check the status of your alarm on installation day.
- If your alarm system needs to be reactivated after Xfinity Voice is installed, you will not be compensated for the cost of reactivation.
- If you change your telephone number, make sure to update your alarm or personal emergency alert response company.
- A backup battery can be installed for your Xfinity Voice modem to provide additional hours of service during a power outage.
- If your battery is missing or depleted and you would like to purchase a new one, visit buy a phone modem battery for your Xfinity Voice service for more information.
