Frequently Asked Questions

How does my ADT alarm system work?

The alarm system may be armed in the “Away” or “Stay” mode. Once the system is activated, each monitored zone has the ability to recognize a violation. Once a zone has been violated, the alarm system then dials ADT and transmits the message through a telephone line. Once the signal is received, the alarm system will wait to send another message if another zone is tripped. Entering the code and turning off the system will end this process.

If I lose power, will my alarm system still work?

Yes. In case of a power loss, the back-up battery will activate to maintain your alarm protection for several hours. In the event your battery is low, a low-battery signal will be sent to your Customer Monitoring Center so you can be notified.

What happens when I press the panic or fire alarm buttons on the touchpad?

If you hold down the panic or fire alarm buttons on the touchpad for 1 to 3 seconds, an alarm is transmitted to the ADT Customer Monitoring Center, and emergency services are dispatched immediately. An alarm received in this manner cannot be canceled.
