What is a false alarm?

A false alarm, also called a nuisance alarm, is the fake report of an emergency, causing unnecessary panic and/or bringing resources (such as emergency services) to a place where they are not needed.


Over time, repeated false alarms in a certain area may cause occupants to start to ignore all alarms, knowing that each time it will probably be false.

Common Causes of False Alarms

User Errors

  • Entering the incorrect security code

  • Accidentally pressing emergency buttons (such as the panic button)

  • Arming the system in the wrong mode (such as arming the system in AWAY mode but staying in the house, which will trigger the motion sensor)

Natural Causes

  • Insects, pets or other animals

  • Flying objects such as floating balloons

  • Strong light reflection from a mirror

  • Strong wind moving a door or window

Defective Device

  • The motion sensor is too sensitive

  • Wiring is deteriorating
