If you make a mistake while entering your code, press the pound (#) button, and then start over. The default code for a DSC alarm is 1234. On some models, this step will reset the alarm and stop it from ringing. This step will also reset the trouble light, armed light, and memory light. If your alarm is still ringing, complete the rest of the steps below.
This also helps to reset the low battery light once the power has been restored. Some DSC models do not have a reset button. If that’s the case, move to the next step.
You may have to reset the date and time if your alarm system loses power.
For example, if the date is September 20, 2022, you’d enter 09 20 22. If it’s currently 2:00 PM, you’d enter 1400.
