Home alarm systems are becoming a common staple in millions of household across the United States while helping to lower petty theft and burglary rates (decreasing nearly 8 percent in 2015 from 2014). Keeping your alarm system up and running at all times helps to deter potential burglars from targeting your home and property by up to 300% If you have a home alarm system installed and you notice a blinking or colored light appearing on the device itself, there are a few steps to take to ensure your alarm is not disabled or malfunctioning without monitoring your property. 

Observe the Color of Your Home Alarm’s Light

The first step to take when a different light appears from your home alarm system is to determine the color of the light itself. In many cases, a solid green light showcases a working system (although it may also blink green on some units). A yellow solid or blinking light may indicate potential malfunctions or trouble communicating with your security service provider. When there is a blinking or solid red light, this may require assistance over the phone with your security company or professional service repair in person. Before making a decision on what to do for your alarm system it is important to first check your device’s manual and instruction guide.

Reference Your Alarm System’s Official Manual and Instruction Guide

Most home alarm systems come complete with an official manual or installation guide. Within the manual, there are troubleshooting sections to help guide you through the process of determining the best course of action to take with new colors that appear on your home alarm (for any reason). 

If you are unable to locate your official home alarm guide or instruction manual, search the make and model of your home security system online for more details regarding colored light indicators

Check the following sections within your reference manual or troubleshooting guide:

  • Installation and Setup
  • Errors With System
  • Troubleshooting (colors, lighting, and system status)

Call Your Security Company for Additional Troubleshooting


When you do not have a guide and require immediate help and assistance, call your security company directly for more information regarding your alarm system and what each color appearing indicates for you. A professional security representative is able to walk you through the process of restoring your system or is capable of providing you with a service technician to help stop colored lights from appearing on your home alarm. 

Whether you have incorrectly entered your home alarm’s passcode or if your system has begun malfunctioning, knowing what to do when a trouble light appears helps to guide you through the process of restoring alarm altogether.
