How to Install a Gas Interlock System: A Comprehensive Guide for Homeowners and Businesses


If you are looking to add a layer of security to your property, a gas interlock system is a great option. This type of security system uses gas detection sensors to alert homeowners or business owners when there is an unauthorized attempt to enter their property. In this article, we will provide a step-by-step guide on how to install a gas interlock system in your property.

Step 1: Choose the Right Gas Interlock System

The first step in installing a gas interlock system is choosing the right one for your property. There are two main types of gas interlock systems: electronic and mechanical. Electronic gas interlock systems use sensors that detect when there is an unauthorized attempt to enter the property, while mechanical gas interlock systems use physical barriers such as locks or gates that can only be opened with a specific key or code.

Step 2: Install the Gas Detection Sensors

Once you have chosen your gas interlock system, the next step is to install the gas detection sensors. These sensors should be placed at strategic locations on your property, such as doors and windows, where unauthorized entry is most likely to occur. It’s important to follow the manufacturer’s instructions when installing the sensors to ensure that they are properly calibrated and functioning correctly.

Step 3: Install the Gas Interlock Control Panel

After installing the gas detection sensors, you will need to install the gas interlock control panel. The control panel is responsible for monitoring the sensors and activating the alarm if an unauthorized attempt is detected. The control panel should be installed in a location where it can be easily accessed in case of an emergency.

Step 4: Connect the Gas Interlock System to the Alarm System

The final step in installing a gas interlock system is connecting it to your alarm system. This will allow the alarm to sound when an unauthorized attempt is detected by the gas detection sensors. It’s important to follow the manufacturer’s instructions when connecting the gas interlock system to your alarm system to ensure that everything is properly configured.


  1. Can a gas interlock system be bypassed?

While it is difficult to bypass a properly installed gas interlock system, it is not impossible. It’s important to keep your gas interlock system well-maintained and regularly tested to ensure that it is functioning correctly.

  1. How often should I test my gas interlock system?

It’s recommended that you test your gas interlock system every six months to ensure that it is functioning correctly. You should also have a professional service come to inspect the system annually to identify any potential issues.

  1. Is a gas interlock system required by law?

While there are no specific laws that require a gas interlock system, some localities and businesses may require it for security purposes. It’s always a good idea to check with your local authorities or insurance provider to see if a gas interlock system is recommended for your property.


Installing a gas interlock system is an excellent way to add an extra layer of security to your property. With the right gas detection sensors, control panel, and alarm system, you can ensure that your property is protected from unauthorized attempts at all times. By following these steps and regularly testing and maintaining your gas interlock system, you can help keep your property safe and secure.
