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.
