Regarding Your Alarm System’s Cellular Transmitter Based on Carriers’ Advanced Mobile Phone Services (AMPS) Discontinuance :

Does my alarm system have an analog cellular transmitter that a cellular carrier may stop servicing?
What is AMPS (Advanced Mobile Phone Service)? What is digital?
How do I know if my cellular transmitter is analog?
Why can’t I just use my analog cellular transmitter?
What happens to my system if I do not replace the analog transmitter?
Will the new digital cellular network work with the old analog cellular network?
When is this going to happen?
What does a cellular alarm transmitter do?
How will the replacement affect my ADT service charge?
What benefits will I get from this conversion?
Who do I call if I have any questions about this change from an analog to a digital cellular transmitter for my alarm system?
Can I do this later and wait until the analog networks are turned off?

Does my alarm system have an analog cellular transmitter that a cellular carrier may stop servicing?
If you received our mailing by direct mail or courier service, ADT records show that an analog cellular radio is part of your security system. Since a shut down of the cellular network that this radio uses would prevent that radio from transmitting signals to ADT, the analog transmitter needs to be replaced with a digital cellular transmitter to maintain the same level of service from ADT.

What is AMPS (Advanced Mobile Phone Service)? What is digital?
Cellular Systems using AMPS technology was originally deployed in the 1980's and 1990's. AMPS has worked fine for alarm systems. As cellular communications became more popular, many cellular carriers wanted more capacity and started using digital technology. Digital cellular signaling was developed to add capacity and additional features. Several major carriers have recently announced that their analog systems will be going out of service.

How do I know if my cellular transmitter is analog?
If your system was installed before 2007, and it included a cellular radio, it most likely has an analog model. If you are an ADT customer and are unsure if you have an analog radio, you may call ADT at 1-800-610-0197 for information.

Why can’t I just use my analog cellular transmitter?
The Federal Communication Commission (FCC) is allowing cellular companies to discontinue providing analog cellular service after February 18, 2008. Several major cellular carriers have announced that they will take down their analog networks after that time. ALL analog cellular devices, including those used with security systems, that rely on those networks may be affected. To operate on the cellular carriers’ digital cellular networks, analog transmitters must be replaced with digital transmitters. Approximately 400,000 remaining alarm industry customers nationwide could be affected by the carriers’ decisions to discontinue AMPS.

What happens to my system if I do not replace the analog transmitter?
If you have an analog cellular transmitter as a back-up method of alarm signal transmission and the analog network it uses is shut off, your security system will not be able to transmit signals to ADT’s Monitoring Centers in the event your standard telephone line service is disrupted. Your failure to replace the analog transmitter together with a carrier’s decision to terminate your analog service will affect ADT’s ability to monitor your home: You will lose the redundancy that cellular parallel protection adds to your ADT alarm system. If analog cellular is your primary and sole method of alarm signal transmission, your security system will NOT be able to send alarm signals to the ADT Monitoring Centers. Your protected property will not receive the benefits of ADT monitoring 24-hours a day, seven days per week.

Will the new digital cellular network work with the old analog cellular network?
Three of the nation’s major cellular carriers have recently announced plans to take their analog networks out of service after February 18, 2008.

When is this going to happen?
The cellular carriers are permitted by the FCC to shut down their networks after February 18, 2008. As the largest single service provider of electronic security in North America, ADT continues proactively contacting its customers to schedule replacement of analog equipment with digital cellular equipment. Please contact ADT immediately if you received a letter or a phone call on this matter and have not yet had your equipment replaced. If you do not contact ADT or return our telephone calls, then we may not be able to maintain your current level of service.

What does a cellular alarm transmitter do?
Cellular alarm transmitters send alarm signals to the ADT Monitoring Centers through wireless networks.

Many customers with a standard telephone line who want an extra layer of protection use ADT’s parallel protection. In the event regular phone service is disrupted (due to construction, power failure, cut or downed lines), the cellular alarm transmitter can send signals to ADT’s Monitoring Centers. This helps prevent lapses in ADT’s ability to provide electronic security services.

SecuritySystem with Cellular Parallel Protection

For customers without a standard landline telephone, the cellular alarm transmitter provides their primary (and only) method of communication with ADT Monitoring Centers.

How will the replacement affect my ADT service charge?
While ADT has no control over the decision of cellular service providers to take advantage of the FCC’s ruling and shut down their AMPS networks, to minimize the impact of the carrier decisions on ADT customers, ADT is paying a considerable portion of the cost of installing new digital devices and altering ADT’s infrastructure. ADT customers who entered into the initial term of their contract and had an analog device installed on or after February 18, 2005 are not being charged ADT’s costs for the digital transmitter. The remaining ADT customers who replace analog transmitters with digital transmitters may chose to pay their portion of the ADT charge through a single invoice or a single credit card transaction.

What benefits will I get from this conversion?
Cellular carriers that shut down their analog networks will not transmit alarm notification signals to ADT from analog equipment at your premises. With a digital transmitter, the alarm system at your premises will be able to transmit alarm notification signals over digital cellular networks to ADT 24-hours per day, 7 days per week.

Who do I call if I have any questions about this change from an analog to a digital cellular transmitter for my alarm system?
ADT customers are encouraged to call ADT at 1-800-610-0197 to review whether their alarm systems use analog (AMPS) transmitters and what steps should be taken to be ready for the February 18, 2008 transition. Likewise, customers who do not have service with ADT should call their alarm service provider for direction and assistance.

Can I do this later and wait until the analog networks are turned off?
Affected alarm customers MUST take action today. If you wait until the analog network you use is turned off, the system at your premises may emit a warning “beep,” signal or message to indicate its loss of connection with its AMPS network. If this occurs, ADT will need to make a service visit to your location to either replace the cellular transmitter with a digital transmitter or disconnect your analog cellular unit from your alarm system. If too many customers wait too long before taking action, ADT may be delayed in responding to customer service requests. Whether your alarm provider is ADT or another company, it is important to respond to notifications about analog cellular transmitters and to arrange for a service appointment immediately. If you know that your alarm system includes an analog cellular device and you have not been contacted by your alarm company, you should contact your service provider directly to schedule a date for service. If you are unsure about whether your alarm system is affected, you are encouraged to contact your alarm service provider. Click here for a Alarm Panel silence commands.
