If you own a smoke detector, you obviously realize how effective they are in helping prevent loss of life and property. But, it is important to understand the differences between the stand-alone battery-operated smoke detector you buy at the store and a monitored home smoke/heat detector installed as part of the ADT Home Security system.
Battery-operated/non-monitored home heat and smoke detectors are not connected to other detectors or warning devices. Your Monitored Smoke Detector is connected to the security system control panel and is monitored by the ADT's Alarm Monitoring Center. If fire strikes, the smoke/heat detector sets off an alarm and a signal is sent to our monitoring center. ADT Home Security, in turn, notifies the fire department, then calls you to verify the alarm.
Your ADT Monitored Smoke Detector provides a quick link to the authorities, whether you are at home, away from home, sound asleep or unable to get to the phone. Our Monitored Photo Electric Smoke Detector also have a built-in Low temperature sensor and built-in high temperature sensor and is designed to detect smoke associated with smoldering.
