How Your ADT-Monitored Burglar Alarm Works

3 cutting-edge technologies detect attempted break-ins

Electromagnetic Circuits

ADT-monitored door and window sensors create electromagnetic circuits on either side of a door or window opening. When the parts are separated, the circuit breaks and triggers the alarm.

Frequency-Sensitive Mics

ADT-monitored glass break sensors come with microphones tuned to the frequency of shattering glass. If a window breaks within a 25-foot range of your sensor, the burglar alarm goes wild.

Infrared Motion Detection

Every ADT-compatible security camera has built-in passive infrared (PIR) motion detection. Cameras send motion alerts to your Command Panel and phone instead of directly triggering the alarm.

It’s hard to think straight in an emergency. Unless you’re ADT.

When you still feel like a deer in headlights, ADT will already be on the line asking if you’re okay and making the next step happen. Do your thinking now so ADT can be there for you later.

What Happens When Your ADT Burglar Alarm Goes Off?

Some burglar alarm systems merely make a loud noise when tripped. But ADT-monitored burglar alarms sound the alarm and contact a 24-hour ADT monitoring center for help.

1. Your alarm system alerts a 24-hour ADT monitoring center.

2. An ADT monitoring representative contacts you to confirm the emergency.

3. Your monitoring rep contacts local first responders if needed.

Frequently Asked Questions

About home security burglar alarm systems

What does a burglar alarm do?

Burglar alarms emit a loud siren when one of your home security devices trips the alarm, alerting you of a potential intruder and deterring them from entering your home.

Are home burglar alarms effective?

In one groundbreaking study of seasoned burglars, 60% said they’d change targets if they saw or heard an alarm on the property.

Do burglar alarms call the police?

Unmonitored or self-monitored alarms don’t call the police in an emergency—that’s up to you.

Monitored burglar alarm systems, on the other hand, alert trained professionals who first confirm the emergency and then contact emergency responders for you.

How loud is a home burglar alarm?

That all depends on the system or devices you’re using. ADT-monitored alarm systems measure at 85 decibels, which is loud enough to be heard virtually anywhere in most homes.

How long do burglar alarms go off for?

That depends on the alarm system. With an ADT-monitored alarm, you will usually be contacted by an ADT monitoring representative within 10 seconds to determine next steps, including whether the alarm needs to stay on.

Why is my ADT-monitored burglar alarm system beeping?

Usually, beeping indicates a recent power outage or low battery. You can clear the alert by entering your passcode and replacing the backup battery if needed. For further help, contact ADT customer support at 1-800-521-1734.
