1. What is Safewatch CellGuard?

Safewatch CellGuard is a service offered by ADT that enables your home security system to communicate with ADT’s Customer Monitoring Centers through the cellular telecommunications networks.

It has become a popular option in home security systems because it helps provide backup protection should your home telephone service be disrupted due to fallen lines, storms or construction.*

*Cellular connections rely on operating cellular device and network services. ADT does not warrant that cellular service will be error free or interrupted as such services are provided by cellular providers.

2. How does Safewatch CellGuard work?

In the event of a telephone or digital voice line outage, or if the phone line associated with the alarm panel is not functioning properly, Safewatch CellGuard can transmit signals through a cellular transmission wireless network.

3. Is Safewatch CellGuard active when phone lines are working?

No, the use of Safewatch CellGuard does not preclude the use of the telephone line. The phone line will remain the primary means of communication.

4. Is Safewatch CellGuard always a backup method of alarm system communication?

No, Safewatch CellGuard can be installed as the security system’s sole or primary means of communication with ADT’s Customer Monitoring Centers (local restrictions may apply). Your ADT Representative can provide you information to help you determine the appropriate home security system configuration.

5. Does Safewatch CellGuard work in the event of a power outage?

Yes, this is another important benefit of Safewatch CellGuard.

6. Do I have to sign a cellular contract?

No additional contract is necessary other than your ADT Services Contract. There is no need to set up any cellular service with a third-party supplier.
