    Disable an ADT Sensor on a Single Door

    ADT alarm systems have sensors that are installed on all access points in your home or building. However, sometimes you need to access a door where the sensor has been damaged or needs to be disabled for an extended period without turning off the whole system. In these cases, use the available disable option. This procedure must be repeated if you later arm your system because rearming enables all sensors. It’s a fast, easy and temporary way to access the door without compromising security in other zones and access points.

    How to Turn It Off

    There are few things more embarrassing than tripping your alarm accidentally. It’s even worse if the police show up, and you must explain why you’re wasting their time. To avoid this situation, here’s how to disarm a single door sensor on ADT systems.

    • On the alarm keypads (the user-control interface), press the Arm key. Then, enter your security code.
    • Press the key button on the keypad to access the bypass menu, and press 1 to activate the bypass zone.
    • Press a scroll key to access available zones. Once the desired door is selected, press the key button.
    • Check to make sure a “B” or “Bypass” appears next to the door zone you are disabling, then press # to exit the bypass setting.

    Note: Some ADT keypads let you enter the zone number you wish to bypass. The zone numbers are documented in the ADT system manual provided by the installer.

    The door sensor will reactivate when you rearm the system. In the meantime, you can replace the faulty sensor or enjoy access to the door without tripping the alarm.

    Importance of Monitored Security Systems

    Bypassing a sensor may sound like the right step for your family to take when construction is happening in certain sections of your home. Or if you’re having a gathering in the backyard and wish to leave everything but your backdoor disarmed. However, bypassing a single door can weaken your home’s overall security. Monitored security, on the other hand, provides around-the-clock protection. Make sure to speak with a security expert for a chance to go through your complete list of questions and for full assistance before tinkering with your equipment.

    Home alarm systems can be monitored or unmonitored. With monitored security systems, you typically sign a contract and pay a monthly fee to have someone watch your back 24/7. With self-monitored or unmonitored home security, you’re responsible for calling for help should the need arise. There is also “do-it-yourself” home security, referring to monitored systems which are self-installed, and no contract systems which provide monitoring without a contract.
