Frequently Asked Questions

How do the ADT burglar alarm systems work?

Our burglar alarms may be armed in the “Away” or “Stay” mode. Once the burglar alarms are activated, each monitored zone has the ability to recognize a violation. Once a zone has been violated, the intruder alarm system then dials an ADT monitoring center and transmits the message through a telephone line. Once the signal is received, the intruder alarm system will wait to send another message if another zone is tripped. Entering the code on the burglar alarm's keypad and turning off the system will end this process with the ADT monitoring center.

If I lose power, will my burglar alarms still work?

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

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

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

Burglar Alarm Monitoring - Why Choose ADT

“I heard a loud noise at the back of my house. Glass was shattering from the sliding door on the patio. ADT called me right away and I told them to send help because someone was in my house. It is reassuring to know that ADT and the police officers were there.”

– Wendy Haughian, Washington
