How to Turn the Volume Down on Your DSC Alarm System – Many people have their DSC alarm system set too loud. Here’s how you can fix that.


Many DSC alarm systems come with a sound control setting that can be adjusted to control the volume of your alarm. This setting helps make sure that the loud, unnerving sound of your alarm will not startle you and your family in the event of an emergency. By adjusting this setting, you can quickly and easily turn down the volume of your DSC alarm system.

Before attempting to adjust any settings on your DSC alarm system, be sure to familiarize yourself with its key features, controls and programming commands. This article provides you with step-by-step instructions on how to modify the sound control settings on your DSC alarm system and decrease the volume of its siren.

Identify Your Alarm System

Before you can change the volume of your DSC alarm system, you need to first identify what type of system you have. Different systems use different methods for changing the volume, and some are more advanced than others. Knowing which system you have will provide you with more information about how to adjust the volume. This section will go into detail about the different types of DSC alarm systems and how to determine which one you have, including any applicable Code Release requirements.

Check the User Manual

It is important to familiarize yourself with the specific procedures and features of your DSC alarm system in order to personalize and adjust your settings accordingly. To do this, it is recommended that you begin by consulting the user manual that came with your system.

The user manual should provide step-by-step instructions for each feature on the keypad. Not only will this help you become more familiar with how to use and configure your alarm system, but it can also provide you with information such as default passcodes, programming instructions and other troubleshooting advice. Additionally, some even offer helpful diagrams and pictorial representations of various features and components; this can be especially beneficial if you are not particularly technologically savvy.

Identify the Model Number

Identifying the model number of your DSC alarm system is important in order to make sure you have the correct information when trying to determine the Steps to Disable the volume of your alarm system. Fortunately, locating this number is relatively simple. There are four possible places where it may be located:

The Package: If you bought your DSC alarm system from a retailer, you will likely find the model number on the package or in any included documentation.

The Part Number Label: The part number label can be located on most DSC family products, commonly near the back or side of select products. It’s often easy to find and often includes a barcode label containing all product information (including model numbers).

Online Database: Some DSC products have an assigned model number that can be found by searching for a specific product name/category via an online database like Alibaba or Amazon. This could also include services and applications released by DSC-affiliated companies such as SmartThings or Cartography Technologies.

Contact Customer Service: If none of these methods yield results, it’s time to contact customer service with any documentation or product identification you do have at hand. Most customer service teams will help guide customers step-by-step in locating their product’s model numbers and provide Steps to Disable the volume on certain models.

Change the Volume

If you’re looking to turn down the volume on your DSC alarm system, you’ve come to the right place. Here we’ll explain the steps you need to take to customize the volume of your alarm and ensure it sounds at the desired level. We’ll also discuss some additional methods you can use to adjust the volume for optimal convenience. Let’s get started.

Access the Control Panel

Accessing the control panel of your DSC alarm system is necessary to change the volume. This can be done by entering in your code or pressing a star key followed by your security code. If you have not registered the installer code for reset, please enter your four digit user code and press [OK] to continue.

Once you have this completed, two small icons will appear on the bottom left hand side of the screen. The first will be a speaker with a plus sign and the second will be a speaker with a minus sign. Select either one depending on if you wish to increase or decrease the volume setting. A bar graph that goes from zero (lowest setting) to five (highest setting) should appear below it designating how loud your alarm is set. As you move up and down on this bar graph, it will indicate what level of volume has been changed to in real time in decibels (dB).

When done changing the settings, go ahead and press [OK] and provide confirmation with another [OK]. Your new settings are now active and your alarm system has been successfully re-configured.

Adjust the Volume Settings

Adjusting the volume settings on your DSC Alarm System can be done quickly and easily. Turning down the volume is relatively simple, as there are several ways to do this depending on the type of DSC system that you have. Each method is discussed below.

On PC1616 series alarms, users can press the * button two times until they reach the “Set Volume” menu. From here, they can choose between four different options to adjust the volume; these include options such as Very Low, Low, Normal and High. To confirm their choice, simply hit “OK” once they select their desired volume level.

For LT type systems like LT25 or LT20 systems, pressing *three times should bring users to a similar menu that allows them to choose between Volume Settings Low (1), Medium (2), or High (3). There is also a “silent mode” option available by pressing 0 which will temporarily mute all outgoing sound from your system in case of an emergency. Users can also adjust their sound settings in more detail using their keypad by pressing # followed by 4 and then selecting one of nine different sound levels for each specific event. By navigating carefully through the menus provided and exploring all available options in detail, users should be able to find a setting that suits their needs.


If you’re having trouble turning down the volume on your DSC alarm system, the first step is to try resetting it. This can be done by disconnecting the power and the batteries for about 10 seconds and then reconnecting them. After doing this, you should try to adjust the volume to see if it has been fixed. If it hasn’t, then there must be another issue causing your DSC alarm system to have a high volume. Let’s take a look at what else you can do to troubleshoot the problem.

Check the Batteries

To ensure that your DSC alarm system runs optimally, it is important to routinely check the condition of the batteries in the alarm equipment. Weak or dead batteries can cause a variety of problems with your alarm system, including a loud siren sound when the system is disarmed instead of going silent. To check and replace your batteries, start by following these steps:

1. Using a Phillips screwdriver, remove the cover to the circuit board. On some models, you may have to open one or more side panels on your system before you can access the circuit board
2. Check each battery connection to make sure it is tight and secure, then look at each battery itself. Replace any batteries that are damaged, low on power or leaking powdery corrosion around their terminals
3. Replace all affected batteries with either standard alkaline batteries or rechargeable NiCad cells depending upon your model; be sure to use only fresh alkaline or fully charging NiCads in order to prevent damage
4. Close up all panels and covers before testing the alarm tones – if everything was done properly, you should notice a decrease in volume

Reset the System

If your alarm system is beeping or playing sounds at an unusually loud volume, you may need to reset the system or check the sound setting. The steps to resetting your DSC Alarm System will depend on the type of system you have. However, most systems require you to enter your master code and press # followed by a numbered key (often 8) to access the programming menu. Once in the menu, use the down arrow key on the main keypad until you get to “Sounds” or “Audio Volume” and then use (the) * key to change it. Pressing * again confirms this selection. In some cases, you may need to enter a multicharacter sequence instead of using * as a confirmation key. Follow any instructions that appear in this step as you work through any additional settings menus.

Once all settings have been changed and confirmed, press * twice followed by # to exit the programming menu and save changes. Now that your alarm settings are changed, try using it and checking the sound level by turning off selected sensors or activatingdoor/window contacts – those should help confirm if everything is working as programmed. With any luck, these steps should have reset your DSC Alarm System for quieter alerting sounds when activated!


By following the simple steps outlined here, you should now have successfully reduced the volume of your DSC alarm system. Not only will this help you to avoid those loud, startling alarms in the future, but it could also help you get a better night’s sleep or feel more relaxed in your own home!
