How To Disarm DSC Alarm Without Code? – Complete Guide!

For users that don’t know how to disarm DSC alarm without code, we’ve prepared a quick and easy step-by-step guide that includes three different methods.

Without the master code, disarming a DSC alarm requires a few more steps but surely there is a way. We made sure to include everything so you can’t go wrong.

Let’s learn more!

To disarm a DSC alarm without a master code, users need to go to Alarm.com and log in to their accounts to proceed. Another way to disarm the alarm entirely is to take out the batteries of your keypad and siren which will turn the system OFF.

What Is The DSC System Master Code?

The master code of your DSC system is used for all functions related to the alarm.

You can perform a reset using the code, arm and disarm the system as you already know, and adjust all of its functions using that exact code.

Without the master code disarming the system will be impossible through the software!

The code cannot be reset unless you know the combination and you cannot reset the system without the master code.

However, there are different methods to disarm the alarm so let’s proceed with the next part of this guide.

How To Disarm DSC Alarm Without Code?

In general, if you don’t have a code, you can disarm your DSC alarm system in 3 ways.

All three ways of disarming the system are similar in difficulty and can be applied as long as you have certain items that will help you turn the device OFF.

Let’s begin with the first and most easy method to disarm your DSC alarm without a code:

Method #1 Disarm Using Alarm.com

If your DSC alarm has been set up using the Alarm.com service, you can easily turn the system on/off from there, as long as you can log into your account.

For this purpose, all you will need is a smart device with a web browser and your credentials to alarm.com.

Here’s how to disarm your DSC alarm using Alarm.com:

Step #1 Access Alarm.com

The first step is to head to the page where you can later insert your login credentials and disarm your system.

Assuming that you already have your internet browser device at hand, open the browser and write “Alarm.com” in the search field.

Tip: There is also an Alarm.com App that is available on Google Play and the App Store.

On a browser, hit the “Search” button for your browser to start displaying the results of the search.

If you’re not redirected straight to Alarm.com, you will have to tap the first result which will send you to the page you want to go to.

Alert: Ensure that your device is connected to the internet since Alarm.com requires an active connection.

Step #2 Login To Alarm.Com

The next step is to log in to Alarm.com using the credentials of the account that has your DSC alarm linked.

Most of the new manufacturers create the registration for their users there and provide them with credentials upon installing their alarm panels.

• If you cannot recall what the credentials were, use the “Forgot my username/password” beneath the login button.

To login to Alarm.com, all you have to do is write the username under the “Username” field and the password under the “Password” field.

Next, hit the “Login” button and you should be able to see your DSC alarm’ status on the homepage of the website.

Note: When logging in to Alarm.com, make sure you’re on the “Customers” page and not the “Partners” page. Your account exists under “Customers”.

Step #3 Disarm The DSC Alarm

After signing in to Alarm.com, it’s time to get your DSC alarm disarmed.

Keep in mind that disarming your camera will turn the device OFF completely and it won’t alert you to intruders until you start the device again from Alarm.com.

Here’s how to disarm your DSC alarm using the services of Alarm.com:

1. Once in Alarm.com, go to Settings.
2. Hit the “Security Tab”.
3. Choose your DSC alarm from the list of devices.
4. Press on “Disarm System” to disarm your DSC alarm.
5. Wait for the system to shut down and disarm.

Alert: Your alarm may take several minutes to disarm completely. Make sure that you don’t interact with the device for the time being.

Method #2 Use A Key Fob

An interesting method to use is a key fob suggested by DSC.

The company has thought that this device would come in handy for users who forget their password or want to arm/disarm their alarm from a distance. They were right.

If you have a key fob, then you won’t need a master code to disarm your alarm since all you have to do is press the “Disarm” button on the key fob to shut off your alarm.

Here’s how to disarm a DSC alarm system using a key fob:

How To Disarm A DSC Alarm Using A Key Fob?

1. Get within 5-10 meters of range within the DSC alarm.
2. Grab your key fob and ensure that the device is functional.
3. Point it towards the DSC alarm’s “eye” (front panel of the device).
4. Press and hold the “Disarm” button on the programmed key fob for your DSC alarm.
5. Once the system recognizes the signal, it will immediately disarm.

Note: Make sure there are no obstructions between you and the alarm, or the key fob will fail to disarm the system.

No Key Fob?

If you don’t currently have a key fob, you can easily get one programmed to your system.

With DSC alarms, you can use the DSC WS4949 Key Fob and program it with your system.

This device can be acquired for less than $6 from the DSC’s website.

How To Program A Key Fob To DSC Alarm?

1. Press and hold the button on the key fob for 3 seconds while pointing at the alarm.
2. Wait for the alarm to go into a wireless enrollment mode.
3. Wait for the alarm to indicate successful programming.

Alert: When buying your key fob, ensure that it has a battery inserted so it can send signals to your alarm.

Method #3 Disengage DSC System

In case none of the methods managed to disarm your system, perhaps you should disengage the alarm if you’re contemplating disarming the system for longer.

Your alarm system consists of two components – the siren and the keypad. You should disengage both of them to make sure that your system is turned off.

Let’s begin with taking your DSC alarm system’s keypad off first:

How To Disengage DSC System Keypad?

1. Remove the keypad from the mounting bracket (some models require undoing screws).
2. Turn the keypad over.
3. Remove the battery compartment.
4. Take off the four AA batteries.

How To Disengage DSC Sirens?

1. Open the front cover by pressing down on the control tab.
2. Expose the batteries inside of the siren.
3. Take off the siren’s batteries.
4. Save the components of the siren in a safe place.

Note: If you wish to rebuild your DSC system back together, ensure that both the siren and the keypad have batteries and are attached to their mounting brackets.

To disarm a DSC alarm without the master code you’ll need to use Alarm.com to disengage the system online or use the Key Fob to remotely disarm the alarm. The best way to turn OFF the system is to remove the batteries from the siren and keypad.

Bottom Line:

Now that we’ve learned how to disarm DSC alarm without code in three different ways, surely one of them will help you.

You should now be able to disengage your DSC alarm without the master code but this is only a workaround. It’s best to re-acquire the code asap.
