Talking about the ADT alarm system, apparently, a typical ADT security alarm system is between 100 and 115 decibels? Can you imagine how loud it is? With the sound that is produced by it, you might get nagged by your neighbors and then you might want to turn it off. However, the issue arises when you do not have the code. Is it possible to turn it off without a code?

Turning off the ADT alarm system even without a code is possible. Depending on the type of the system, here are some options to choose from, including locating and removing the transformer unplug from the outlet, disassembling the security panel, and removing the backup battery

The ADT security systems vary. While there are different, all of them essentially follow the same routine. There is a panel box in many of the older ones and it is separate from the keypad. The panel box is the one where the battery if found. After unplugging the large, square plug that is usually screwed into the power outlet called the transformer, it will be needed for you to get the access to the panel box. For those who currently live in a home that has installed the system in the past, it is possible for the panel box to not be able to be accessed through the traditional methods, such as a key. You will need to find out how to access the battery with the exception if the previous owner or renter provided you with one.

Just like how 9-volt batteries attach to a plastic or rubber flap with both a positive and negative terminal, the battery is usually attached by two leads. All that you have to do is to disconnect it and after the transformer is unplugged, the alarm should stop. In case there is no way for you to find the transformer or if it is screwed in, it is better for you to just cut the power from the circuit breaker. Then, get rid the battery. When everything is done, it is time for you to find and remove the transformer.

Talking about the battery, you have to know that some of them will be found in the security panel itself. They are adjacent to the keypad or directly behind it. There are a few kinds of ADT home security systems and most of them are Honeywell products, which is now known as Residio. Each of them has a battery backup and each of them draws the main power from an AC outlet.
