Step-by-step Instructions for How to Arm an Alarm System

Step 1: Inspect the Windows

Make sure that all windows and doors are closed before arming the system. This will help ensure that no unwanted intrusion can occur while the alarm is armed. 

Most systems have a “perimeter arm” setting, which arms the entire outside perimeter of your home or business. This setting is most useful for situations where you want to ensure that all entrances and exits are protected.

Step 2: Activate the Intrusion Detection System

Activate motion detectors, door contacts, and other intrusion detection devices. This will allow your alarm system to detect movement inside your home or business while the system is armed. 

Auto-stay is a feature that keeps the alarm system armed even after the main door has been opened. This ensures that if someone tries to enter through a window or side door, they will be detected, and an alarm will sound.

Step 3: Activate the Panic Button

Most systems have a panic button that can be used in an emergency. If activated, your alarm system will sound and alert you or others nearby that something is wrong. 

If available on your system, activate voice notification. This feature allows the alarm to speak a pre-recorded message when triggered, providing additional warning to intruders before the alarm sounds.

Step 4: Set Remote Access Codes

If you have access to a keypad or remote, set an access code for yourself and anyone authorized to enter your home or business while the alarm is armed. Only those with permission can disarm the system without triggering an alarm.

Step 5: Test the System

Once all the settings have been configured, testing the system to ensure it is functioning properly is important. Do this by opening a door or window while the alarm is armed and verifying that it triggers an alarm. Be sure to keep your alarm system software up to date. 

This will ensure that it operates at peak performance and any critical security updates are applied.

Step 6: Contact Monitored Alarm Center

Contact the monitoring center for additional setup instructions if you have a monitored alarm system. They can provide information on setting up remote access, testing the system, and more.

Tips for How to Arm an Alarm System

  1. Familiarize yourself with the alarm system and its controls before arming it; ensure you understand how to arm, disarm, and reset your system if necessary.
  2. Always lock all doors and windows connected to the alarm system before arming it.
  3. Ensure any pets in the house are accounted for when you arm the alarm – they could trigger the sensors if an animal wanders into a protected area of your house while it’s armed.
  4. Set the alarm system to a mode that will work for you and your family’s needs; generally, three levels of security are available, depending on how cautious you wish to be.
  5. Ask your alarm service provider to provide a regular maintenance schedule to ensure the system is in good working order.
  6. Ensure all your family members know how to correctly arm and disarm the alarm system. This will help reduce false alarms caused by mistakes during activation.

When arming an alarm system, following these guidelines can help ensure everyone remains safe and secure. By following these tips, you can ensure your alarm system will be effective when needed.

What’s the Best Way of Ensuring That Your System Is Armed Correctly?

To ensure that your system is armed correctly and securely, you should always make sure to do a few quick checks. First, look for any signs of tampering around the alarm panel or other equipment connected to it. Also, check that the connections are secure and that no wires are loose. If you have sensors installed in other parts of your property, take a few moments to check those, too.

Ensure that all doors and windows are securely shut and locked before arming your system, as an open window or door can defeat the purpose of your alarm. Finally, double-check that all the sensors and other devices are enabled for your system – this might be indicated by a light or message on the alarm panel.

Entering the Wrong Code or Password

Once you have done all these checks, you can arm your system and activate the security measures.

What Happens If You Make a Mistake When Arming Your System?

If you make a mistake when arming your system – for example, entering the wrong code or password – you may be alerted to this immediately. Some systems will sound a loud alarm and emit a strobe light, while others will simply display an error message. If your system is triggered due to a mistake in arming, you should contact your security company immediately.

This way, they can reset the system and check that everything is working correctly again. It is important always to follow the instructions provided with your system carefully, as this will help ensure that you arm it correctly and reduce the risk of any mistakes or false alarms being triggered.

What Other Measures Should You Take When Arming Your System?

In addition to following the instructions supplied with your alarm system, it is also important to take a few other precautions when arming it. For example, you should ensure that everyone in the household knows the code or password and how to arm and disarm the system correctly.

You should also ensure that visitors or guests are kept from the code or password for your system, as this could potentially result in a false alarm or other issues.

Finally, keeping any spare keypads, remotes, or passwords securely stored away and out of sight is important. By following the steps outlined above, you can help ensure that your system is armed correctly and securely without any mistakes or errors being made. This will help to keep your property and possessions safe and secure.

What Should You Do in a False Alarm or Any Other Emergency?

False alarms can be triggered if you ever mistakenly arm the alarm system. To help avoid false alarms, here are a few steps to take:

Animal Moving in Front of the Motion Sensor
  • Ensure all doors and windows are securely closed and locked before arming your system.
  • Check that no objects are blocking motion sensors outside or inside your home.
  • Test the system to make sure it is functioning correctly.
  • Ensure everyone in your household knows how to disarm the alarm system properly and what steps to take in any emergency situation.
  • Familiarize yourself with your alarm system’s manual so you know the exact protocol for false alarms or other emergencies that may arise.
  • If a false alarm does occur, try to determine what caused it. This could be anything from an animal moving in front of the motion sensor to an open window when you armed the system.
  • Once the cause of the false alarm is determined, take measures to prevent it from happening again, such as ensuring all windows and doors are locked or relocating any obstructions near the motion sensor.
  • Contact your alarm company if you need assistance resetting or reactivating the alarm system.

Following these steps can help ensure your home is secure and protected from false alarms or other emergencies. Remember that arming an alarm system is not just about protection but also about peace of mind. Take the time to understand your system, and you can arm it safely and effectively.


In conclusion, arming an alarm system is a great way to protect your family, home, and valuables. To ensure the highest level of security, the keypad should be placed in a visible spot near the door or entryway when arming the alarm system. It’s also important to remember that some systems can only be armed manually, while others are programmed to arm themselves automatically after a certain time. 

With some research and patience, arming an alarm system can be a simple task that helps bring peace of mind. Reading this post has helped you learn how to arm an alarm system. Make sure the safety precautions are carried out in the order listed.
