What Causes False Alarms?

False alarms in the home security system are typically not a big problem.

The one thing that most commonly causes them is to set your alarm system while leaving a door or a window ajar. Once that happens, the alarm is set and the home security is of course not secure and within a few minutes will begin to sound.

In many cases, you're hearing the alarm sounding nearly before you've gotten out of the driveway, which typically tells you that the alarm isn't from an intruder.

If a door or a window isn't locked and is left slightly ajar, or a pet nudges it open, the doorway will of course break the circuit and the alarm goes off.

In most cases, this is due to human error. Well, in some cases, it may be animal error too, as many times the alarm may be sounded or the issue occurs because of our pets.

A few things can cause a home alarm system to go off by itself, but for the most part, it can be prevented.

Doors which are slightly loose and don't have felt or plastic stripping in place can blow in the wind and create an illusion for the alarm system which will trigger the alarm, the monitoring company , the police and anyone else that you might like to consider. Some doors that are more difficult to secure can actually blow open and cause an alarm to trigger.

Make sure these are locked and secured tightly so that the motion detector or the circuit isn't broken or triggered, causing you a bit of inconvenience and not a small amount of embarrassment.

Some alarms are not equipped with a window detector , but your window can still set off the alarm by creating movement inside your home that your detector will pick up on. Fans or other objects that move the air will also create an alarm scenario when they cause movement of plants, or other household items.

How to determine what causes false alarms may not always be an easy task. The culprit could be a window, a door, a blowing curtain, or even a cat instead of a cat burglar. Often the object that set off the false alarm will be a door or a window, a cat, a curtain, or anything aside from an actual burglar or intruder into your home.

Alarms going off by themselves do not happen often but when they do, it could easily have been prevented. Be certain that when you leave your home, before you switch on that alarm, that all of the doors, windows and other areas are locked up and that you've secured any rattling windows or other items that could lead to a false alarm in your home.
