ADT-Monitored Smoke Detector

Breathe Easy Knowing We're helping to protect you at All Times

The ADT-Monitored Heat Sensing Smoke Detector stands guard night and day to help protect your home and family from fire. Whether you’re home or away, ADT will send emergency services immediately to help minimize property damage and give you time to get your loved ones to safety.

Here’s How It Works

There are two main types of home smoke detectors: ionization and photoelectric. An ionization smoke alarm (the kind ADT monitors) detects smoke when it disrupts the ionizing radiation occurring in the device.

A photoelectric smoke detector is triggered when smoke obstructs the light beam in the sensor.

Double the Protection

ADT monitored smoke alarms provide dual-sensor heat detection: rate-of-rise and fixed-heat sensors.

The rate-of-rise sensor will trigger the smoke detector when rapid spikes in temperature occur in your home. The fixed-heat sensor will set off the alarm when the temperature in your home reaches 177° Fahrenheit.

Help Ensure Your Pets Stay Safe

Fido and Fluffy are family too. But they can’t get to safety on their own. In case of fire, your smoke detector will communicate with your security system and notify one of ADT’s six monitoring centers They will then alert your local fire department.

Frequently Asked Questions

How do I change my ADT monitored smoke detector battery?

First, put your security system in test mode. Remove the smoke alarm by turning in a counter-clockwise direction. Switch out the batteries and replace the detector by turning clockwise. Ensure that it’s securely in place. Then, turn off test mode.

Why is my ADT monitored smoke detector beeping?

A beeping fire detector typically indicates a low battery. Change the battery as soon as possible to ensure your smoke alarm helps to protect you and your family properly. It could be time to replace the detector entirely if the beeping continues after you’ve changed the battery.

How do I turn off my ADT monitored smoke detector?

Check your specific instruction manual to learn how to operate and turn off your ADT Monitored Heat Sensing Smoke Detector.

How long does my ADT monitored smoke detector last?

Most home smoke alarms last about ten years. However, you should always check your owner’s manual for guidelines on when to get a smoke detector replacement. If you hear chirping even after putting a fresh battery in, it’s time to get a new one.
