How to remove your intruder alarm – Step-by-Step

  1. Notify Your Alarm Monitoring Company

If your alarm system is monitored inform the company that the alarm system is being removed and that you are deactivating the system. This will prevent any false alarms and potential emergency response fees.  Make sure any contracts are cancelled.

  1. Disarm the System

Disarm the system using your code. This ensures that the alarm won’t be triggered during the removal process.  You may need the engineer code.

  1. Disconnect the Power Supply

Battery Backup: Locate the control panel and open it. Disconnect the battery backup to ensure this is removed before the next step.

Main Power Supply: Turn off the main power supply to the alarm system. This is typically done by a fused spur first then ensure the circuit breaker at the main electric board is turned off. Ensure you have correctly identified the circuit controlling the alarm system before turning it off.  Test the mains voltage to ensure safe isolation.

  1. Remove the Control Panel

Follow these steps to safely remove it:

  1. Open the control panel casing using the appropriate tool.
  2. Disconnect all wiring. Take note of the wire connections. TIP: Take a photo also so you have a record of the connections and cable colours.
  3. Unscrew the control panel from the wall.
  1. Remove the Keypads

Keypads are usually located at the point of entry to the home.

  1. Open the keypad casing. TIP: Take a photo also so you have a record of the connections and cable colours.
  2. Disconnect the wiring.
  3. Unscrew the keypad from the wall.

Door and Window Sensors:

  4. Unscrew or unclip the detectors from their mounts.

These devices are usually mounted at higher level.

  2. Disconnect the wiring.
  3. Unscrew and remove the device from this location.
  1. Ready for Decoration

After all devices are removed, you’ll likely have small holes where they have been installed.

Patch these holes with the correct filler ready for repainting.

  1. Dispose of Old Equipment Responsibly

Many electronic components contain materials that should not be disposed of in normal rubbish collection especially batteries.

Tips and Considerations

Handle with Care: Alarm devices are often small and fragile, so handle everything carefully to avoid damage.

Document the Process: Taking photos during the disassembly can help if you need to reinstall the system.  This will help in future.

Check for Hidden Components: Some systems have hidden or less obvious components like small springs, resistors and screws.  Make sure everything is collected and stored safely.
