How to Disable a Security Alarm

Security systems are useful because they are deterrents to thieves and vandals while providing homeowners with peace of mind. One common problem with security systems is a false alarm. False alarms can be expensive because they can result in fees from the alarm company and fines from the police or fire brigade if they are dispatched in response. Disabling a security alarm can be done quickly when necessary.

Skill level:


  1. 1

    Locate the main security panel in the home. Some systems rely on one central panel that controls the whole system, while others use multiple panels throughout the home. Find the nearest one with a keypad that will enable you to disable it.

  2. 2

    Enter the security code into the panel. Each system has a numerical code that shuts off the system and disables an alarm. Punch in the code, and turn the system off to prevent another alarm activation.

  3. 3

    Call the security company. If an alarm goes off, a dispatcher will frequently call the home, but if he doesn't, notify the company that an alarm is going off. If you can't remember the security code, you'll likely be asked for a password on the account. Provide the password and your name, and the security company can disable the alarm remotely.

  4. 4

    Unplug the phone jack. For most alarm systems, the phone line is the system's only link to the dispatch centre, so disconnecting the phone line can shut the system off.

Tips and warnings

  • False alarms are not only expensive, but they can slow the response time of emergency services in the event of an actual alarm or emergency.
