Understanding False Alarms and How to Prevent Them


Home security is a vital aspect of any household. A false alarm can cause distress and panic among homeowners as well as waste valuable resources of emergency services. Understanding false alarms is crucial to prevent them from taking place. In this article, we will discuss what causes false alarms and how you can prevent them from happening.

What are False Alarms?

A false alarm in a home security system is an occurrence in which the alarm goes off without an actual threat to the home or its occupants. False alarms can be triggered by a variety of sources, including pets, faulty equipment, and user error.

False alarms are a common occurrence in home security systems which can result in a nuisance as well as a waste of valuable emergency resources. In the US alone, it is estimated that over 90% of all alarms that emergency services respond to are false.

Causes of False Alarms


Pets in the home can often cause false alarms. Pet movement can trigger motion sensors, which in turn can set off the alarm. To avoid this, pet owners can install pet-immune motion sensors or adjust the sensitivity of the existing ones.

Faulty Equipment

Faulty equipment is also a common cause of false alarms. Outdated equipment or malfunctioning sensors can trigger the security system improperly. Regular maintenance or upgrading of your equipment can help prevent these false alarms.

User Error

User error is another significant factor for false alarms. Accidentally triggering the system by entering the wrong access code or forgetting to disarm the security system can cause false alarms. Educating all users of the system and practicing the necessary steps to avoid these errors can prevent false alarms.

Preventative Measures

Regular Maintenance

Regular maintenance of home security systems can help prevent false alarms. This includes checking the batteries in all sensors, verifying the power supply, and ensuring the wiring is intact.

Professional Installation and Upgrades

Having your security system professionally installed and updated can also help prevent false alarms. Upgrades to newer equipment can significantly decrease the chances of your system malfunctioning and triggering false alarms.

Pet Immune Motion Sensors

If you have pets, installing pet-immune motion sensors can prevent them from triggering false alarms. These sensors are designed to ignore the movement of animals up to a certain weight limit and can reduce the chances of false alarms.

User Education

Educating all users of the security system on the proper steps to avoid false alarms is essential. This includes ensuring all users know how to properly disarm the system, enter the correct access code, and understand the consequences of false alarms.


False alarms can cause significant distress and wastage of valuable resources. Understanding the causes of false alarms and taking necessary preventative measures to avoid them can help keep your home secure and minimize the risk of a false alarm. Regular maintenance, professional installation and upgrades, the use of pet-immune motion sensors, and user education are critical steps in avoiding false alarms. With these measures in mind, you can help minimize the risk of a false alarm and keep your home and valuables secure.
