If your DSC security system was affected by a power outage, you’ll need to reset the system before it will be operational again. Here’s a quick guide on how to do that.


Power outages are a common occurrence, and they can cause your home’s security system to reset. A reset can leave your home vulnerable and unprotected, so it’s important to know how to reset your DSC alarm system after a power outage. To help you out, here is a step-by-step guide on how to reset your DSC alarm system after a power outage.

Before doing anything else, make sure you have the correct model number for your DSC alarm system. This is important because not all DSC alarm models are the same, and some require different steps than others. Once you have the correct model number in hand, follow these steps:

1) Locate the main power supply switch for the alarm system – this will usually be located in an easily accessible cabinet or drawer.

2) Turn off all of the breakers related to the system then disconnect them entirely from their respective outlets.

3) Wait at least 30 seconds before turning them back on, starting with the main breaker first then proceeding with other breakers that are related to the alarm system.

4) Reconnect all of the line cords (data cables).

5) Turn all of switches back on and proceed with any other individual keypad settings as necessary (i.e., code changes).
Once these steps are completed in order, your DSC alarm should be reset and ready to provide protection against unauthorized entry!

Safety Considerations

Before attempting to reset your DSC alarm system after a power outage, you should always take appropriate safety precautions. Make sure that all of your housemates are aware of the situation and that everyone is in agreement about the process of resetting the system. Additionally, when working on an alarm system it’s important to keep an eye out for any potential hazards that might be present, such as exposed wiring or debris left behind from the storm.

When attempting to reset your DSC alarm system, there are a few key steps that you’ll need to take in order to ensure that the reset process is completed safely and properly. First, it’s important to identify which type of power outage has occurred – either a manual or an auto restart. If a manual restart is required, then you will need to open up the control panel and manually reboot the system by pressing and holding down two buttons simultaneously. If an auto restart is required, then you may need to enter your security code in order to reactivate the alarm system itself. Finally, it’s important to test all of your sensors throughout your home after you complete the reset process in order to make sure everything is functioning correctly

Understanding Your System

It is important to understand how your DSC alarm system works before attempting to reset it following a power outage. Doing so will help you better understand how to quickly and accurately reset the system. It’s good practice to familiarize yourself with the components of your system before attempting any kind of reset. This will help ensure that you do it in the correct manner.

Identifying Your System

Before you can reset your DSC alarm system after a power outage, you need to identify the model and serial number of the system. You may be able to find this information on a sticker or plaque connected to the alarm panel. Alternatively, you may need to access the service menu on some models. If you cannot locate this information, contact your alarm company or technician to learn what type of system you have before attempting a reset procedure. It is important to follow instructions carefully so as not to cause damage or void any warranties that might be in place on your security system.

Locating Your System’s Keypad

If you have an alarm system, resetting it after a power outage is an important step for getting your system back up and running quickly. Before resetting your DSC alarm system, you must locate the keypad. This can typically be found near a main entry door. Depending on the type of system you have, your DSC security keypad may be located inside or outside of your home.

If you are unsure where to locate your keypad, consult the manual that came with your security system or contact the manufacturer or installer for instructions. Once you are able to identify where to find the keypad, press “* + 2” on the numeric keypad in order to reset the system. The armed light at the top of the screen should blink and then go solid once reset is complete. You will then need to enter in a four-digit user code in order to disarm it and set it back up according to how you prefer.

Resetting Your System

After a power outage, your home’s security system may need to be reset. This is because the system has to be reset to allow it to properly protect your home from intruders. Different types of systems will require different steps to be taken in order to reset it. This article will explain how to reset a DSC alarm system after a power outage.

Disconnecting the Power

If your DSC alarm system has lost power due to a power outage, it is important to reset the system correctly. First, you will need to disconnect the power from the system. To do this, locate the circuit breaker for your DSC alarm system and switch it off before starting. Then, wait for about 60 seconds before restarting. This will help clear out any residual power that may have been left in the components of the alarm system. Once disconnected from power, you are ready to begin the resetting process.

Re-Connecting the Power

Once power to the system has been restored, it may be necessary to re-connect the power in order for the system to begin functioning properly. Depending on how your system is configured, this may vary. To re-connect the power:

1. Confirm that all control panel code changes have been made as necessary (this step may not be required).
2. Reset all of the devices connected to your DSC Alarm System (such as security sensors and digital keypads) by pressing each one’s “reset” button or switch until you hear it make a sound or see a light flash.
3. Plug in your DSC Security System’s power adapter and wait for up to 60 seconds for it to reset and turn back on automatically. This should also show up on your digital keypad as a message saying “Switching To Normal”.
4. If after 60 seconds you do not get any indication that your system is powering back up, press and hold down the “reset” button or switch on its power adapter until you hear a beeping sound, indicating it has been reset properly.
5. Next check each device connected to the alarm panel itself (wireless receivers, wireless keysystems etc.) are properly powered and communicating with your control panel correctly

Entering Your Master Code

The first step in resetting your DSC alarm system after a power outage is to enter your master code. Your master code is used for arming and disarming the system and overriding any alarm notifications. Once you enter your code, you may be prompted to enter a secondary user code depending on your system programming settings.

To enter your master code:

1. Enter the section of the keypad that requires entering the master code (e.g., when pressing “Disarm”, “Arm away”, or other mode selections).
2. Using the keypad, type in the four-digit master code followed by #. The system should then respond appropriately to confirm the successful entry of your master code, such as “Master Code Accepted”.
If you have an LCD keypad, you may also need to press “ENTER” button after entering each set of numbers for it to be accepted by the system. Note that some LCD Keypads require two presses of “ENTER” – one at the end of each four-digit “half” or group of numbers in your Master Code (e.g., “4567# ENTER # ENTER”).
3. This should activate all features associated with entered user level access, allowing you to control and manage whatever features are associated with this user level access given its programming permissions on the panel itself.
4. Once successful entry has been confirmed, proceed with commands or settings necessary during this session according to what needs resetting due to power loss recovery needs (i.e., reinstalling program settings per panel history log information.)

Performing a System Test

Once power is restored, it’s important to perform a complete system test to ensure that all components are working properly. This will usually include checking the control panel, keypads, interior and exterior sirens, sensors and accessories.

To begin the system test, you’ll need to first access the programming mode by entering your master code at the control panel. If you do not have a master code set up on your system yet, you should refer to your user manual for information on how to do so. Once inside programming mode, go through each section of your alarm system while documenting any issues found along the way. This could include testing each sensor or accessory one-by-one or running an entire zone test depending on what type of system you have in place.

Testing of wireless radios should also be done if applicable alongside with checking the signal strength and battery status indicators. Lastly, review any event logs on your panel to make sure there weren’t any missed signals before testing was initiated as well as confirming all communication pathways are operating correctly. A successful test result should provide peace of mind and confidence moving forward that no issues were left unresolved after a power outage has occurred.


When you experience a power outage, it can be challenging to know how to reset your system. While the process of resetting a DSC alarm system may vary slightly depending on your specific setup, the important thing to remember is to not re-enter any codes until you are sure that power has been fully restored. Doing so will ensure that you don’t run into any issues when trying to reactivate the system and access its features.

Once you have identified the cause of the power outage, make sure that all components are working correctly and that all System arming/disarming methods (such as Keypads, Wireless Remote Controls, Optional Wall Key Switches) denote they are active and working properly. After checking everything, enter your Master Code and rearm your system. It’s also a good idea to check with your alarm company if the alarm is monitored before resetting it. Following these simple steps will help get your DSC alarm system up and running safely after a power outage.
