You should know how to disarm your home security system in the event of an emergency. Here’s a step-by-step guide on how to do it.

Identifying Your System

Knowing how to disable your home security system can be a valuable skill if you ever need to reset or troubleshoot it. Before you can begin, you need to correctly identify the type of system you have installed. Depending on the type of system, the steps you take to disarm it will vary. Let’s take a closer look at the different types of home security systems and how to identify them.

Determine the make and model of your system

The first step in disarming your home security system is to determine the make and model of the system so you can look up the specific instructions for it. Make sure that you verify the exact model by checking either the panel, your user manual or by searching online with relevant keywords. If you are unable to find information on your system, then contact a professional fire and security technician who can provide further guidance.

Once you have determined the type of system you have, locate your control panel. Modern panels are powered either by batteries or a power supply, depending on the make and model of your system. If it is battery powered, open up the panel with a coin and replace any worn batteries as needed; if it’s powered, check that power is supplying to both sides of the panel (positive and negative).

If connection is established to both sides of the panel, look for an emergency disarm switch. This switch allows quick access to temporarily disengage all components connected to your system from a central location. Check if there is an ‘arm’ switch which will show in what mode it is set at – normally green for armed and red for disarmed. Once done so, refer back to your user manual to learn how to properly disarm any/all additional components such as motion sensors or glass break detectors connected wirelessly or via hard-wired cables respectively.

Identify the type of security system you have

Before you can attempt to disarm your system, it helps to understand what kind of security system you have so that you can accurately assess the situation. Here are some of the most common types of home security systems:

Hardwired Systems: These are wired into your home’s electrical outlets and may include an alarm panel to control the system. Many hardwired systems require a landline connection for monitoring by a monitoring center 24/7.

Wireless Systems: These communicate via radio frequencies rather than through wires. They are easy to install and require less maintenance; however, they usually require batteries that need replacing periodically and can experience interference from electronics or appliances in the home that transmit signals on similar frequencies.

Monitored Systems: Monitored systems have a monitoring center that is able to alert police or fire officials if an alarm is triggered and respond accordingly. While this type of system offers a higher level of protection, there is usually a fee associated with the service.

Unmonitored Systems : Unmonitored systems solely serve as a silent alert within the home but provide no notification outside of it if an alarm is triggered. This type of system may also be referred to as an audible-only system or bell-box technique, as it will emit loud audible tones when triggered.

Disarming the System

Disarming your home security system is an important part of keeping your property safe. Knowing how to properly disarm your system will ensure that you are only allowing those you trust into your home. There are a few different ways to disarm your home security system, so it is important to familiarize yourself with the specific instructions for your system. Let’s take a look at the main methods for disarming your system.

Enter your code on the keypad

Once you have located the control panel, you will be asked to enter a passcode. Depending on the type of home security system that you are using, your code may consist of a combination of numbers, letters or symbols. Make sure to enter the passcode slowly and precisely to ensure that it is accepted. After entering your code, look for any text or display lights that indicate whether you have been successful in disarming your home security system. If your code was correct and accepted, the system will exit “alarm mode” and become inactive.

If your code is incorrect, some systems will alert you with a warning message such as “Invalid Code” or “Code Not Recognized”. After several unsuccessful attempts to disarm your home security system with an incorrect code, it is likely that your alarm will begin to sound indicating an alarm condition until the correct code is entered into the control panel’s keypad.

Additionally, some systems provide alternative means for disarming beyond simply entering a pre-set passcode into the keypad. You may also be required to utilize something like a handheld remote device or even include biometric verification techniques such as fingerprint scanning in order for access rights to be granted and the main alarm cell itself deactivated. Regardless of which type of security system you use in your own residence, it’s important for homeowners to take necessary steps towards understanding how their alarms can best be disabled during times when disconnection from armed protection is preferred.

Disable the system manually

Taking your security system offline, or completely disabling it, is simple but the process may vary depending on the type of system you own. First, locate and enter the control panel of your system. For wired systems, this will be found inside and be easily accessible through a closet or basement door. Wireless systems are often stored in plain sight in areas that are easily accessible such as entry ways or doors. To disable your system manually, it is best to find out from the manufacturer what method needs to be taken to deactivate it; most methods require a combination of “master code” pressing certain buttons within a certain time frame. After completing this step, disconnect all power sources including batteries if possible before ending with a confirmation via on-screen message that the system has been disarmed. Keep in mind to wait for confirmation before leaving; otherwise you risk not being armed against potential threats while away from home.

Use a smartphone app

Using a smartphone app to disarm your home security system is a great way to make sure you keep your home safe and secure. Most modern home security systems are compatible with downloadable apps that allow you to stop and start your alarm from anywhere in the world. After downloading the app, it should be easy to create an account and register with the specific app and monitor service. Once everything is set up, you can simply log in with your username and password to arm or disarm your security system.

When using the smartphone app, it’s important to remember that some devices might require additional setup for full remoteness capability. It’s also important to keep in mind that any changes made within the app will only last for a certain period of time before needing another change of settings or reconfirmation from a registered administrator user. Lastly, some home security systems may require a PIN code (or similar authentication) sent via SMS before allowing changes or disarmament on the system. Additionally, if you ever forget your smartphone while traveling – there are other ways of disarming such as using a keypad directly on the control unit or remotely through an interactive service provider like ADT Security Services.


If your home security system won’t disarm, it can be very frustrating. There are a few different things that may be causing the issue, and it’s important to troubleshoot the problem before you move on to more complex solutions. In this section, you’ll learn about the most common causes of a malfunctioning home security system as well as how to diagnose and fix the issues.

Check the battery

Checking your system’s battery life is an important part of troubleshooting and should always be the first step. Many modern home security systems have a built-in backup battery which powers the system in the event of a power outage. The longevity of the battery will depend on usage and settings, but it is important to check to see if it needs to be replaced. If your alarm has been activated or tripped in the past, use a voltmeter or multimeter to test its voltage level before replacing. If it indicates low voltage, replace it with a new 9-volt battery. Once that is done, check all wires are securely connected and then reset your system.

Check the power source

Before you attempt to disarm your home security system, it is important to check that its power source is functioning properly. This can be done quickly by checking the voltage at the circuit breaker and/or mains power supply (if using a wired system). If you are using a wireless home security system, then it will require battery power. Check for any connections that might have come loose or any corroded wires, and replace or repair them if necessary. If your alarm system has been plugged into an outlet, test it by switching the outlet on and off several times to make sure the electrical connection is secure. You may also need to adjust your battery settings appropriately; consult your user manual or contact customer service for assistance in doing this. Once you have confirmed that there is sufficient power running to the alarm system, you can proceed with disarming it.#

Check the sensors

When troubleshooting errors in your home security system, it is important to check the sensors first. All of the motion sensors, door window sensors, and other detectors that are part of the system are necessary for it to fully secure your home.

Start by checking the exterior doors and windows for signs of tampering or a sensor that has been triggered out of place. Check all cabinets and drawers as well for intruders who may have bypassed your interior sensors. Then make sure all internal motion detectors, contact switches, heat and smoke detectors are in proper working condition. Ensure that all connections between components such as windows and door contacts are clean-there should not be any corrosion or dirt buildup on them. If you find traces of either, clean the connections before continuing with further troubleshooting.

You should also make sure that the security system settings have not been altered or changed by an intruder. Check if your cameras are still protecting what they should be protecting and if any settings have been changed in your central control panel-if so, notify your service provider immediately to get help resetting them back to their original configuration.

Resetting the System

Resetting your home security system is an important step to take when you need to reset the system. It’s a simple process that can be done quickly, and it’s important to make sure you do it correctly. This article will explain how to reset your home security system and what to do if you encounter any issues along the way.

Reset the system using the keypad

Resetting the system using the keypad is a quick and easy way to disarm your home security system. Depending on the type of system you have, resetting could be as simple as pressing a few buttons or may require additional steps such as entering a code.

For the majority of systems, resetting will involve looking for a button marked “reset” or “disarm” and pressing it. This button may be labeled in one of several ways, including “C/D,” “MST,” or “Disarm”. It should generally be located near the control panel or on one of the security pads. Other systems may require you to press a sequence of number keys or enter in an access code before completing the reset process.

In some cases, the numbers that must be entered are printed right on your keypad so you don’t have to remember them by heart. As soon as you’ve reset your security system, you should get a confirmation that it has been properly disarmed and set back to its original state. Remember – if something doesn’t work correctly after resetting your system, contact your alarm company for help!

Reset the system using a smartphone app

The ability to reset your home security system using a smartphone app is an incredibly useful tool and can be done in just a few steps. This can be especially helpful for when you need access to your house when you are away and don’t have access to the traditional keypad or other control device.

To reset the system using a smartphone app, start by making sure that all doors, windows, and any other entry points are tightly shut. Then open the app on your phone and ensure that it is connected to your home security system. You may have to enter in your user name or password if prompted. Once the app is connected, select the ‘reset’ option from within the menu of options on the home security system.

The final step is to confirm that you wish to reset your system by pressing ‘yes’ or ‘OK’ depending on what type of control method has been chosen. Once this option has been selected, the reset process will begin and your house should now be disarmed until it needs to be re-armed again at some point in time.

Contact your security provider for assistance

If the process of resetting your security system on your own doesn’t work or is taking too long, then it’s time to get professional help. Contact your home security provider, either via telephone or online support, and provide them with your account information and a description of the issue you are having. A representative will be able to walk you through the steps needed to reset your security system and/or take further action as necessary. Some home security providers also have access to remote diagnostics which can enable them to diagnose problems from afar and fix issues quickly. Make sure to follow their instructions closely so that you don’t feel insecure that your home is not well protected.
