False Alarms

Preventing False Alarms

False alarms are costly to everyone

False alarms take police away from real emergencies. They can endanger responding authorities and your entire community. Setting off a false alarm is like dialing 9-1-1; the police will respond thinking there is a real problem. False alarms may lead to neighbors ignoring your alarm. It’s like “Crying wolf” and can, in effect, make your security system seem less credible. False alarms may make you reluctant to arm your system – exposing your home or business to undetected breaches of security.

False alarms are generally caused by user error. Many cities charge fines for excessive false alarms so it is important for customers to understand the operation of their security system.

Common causes of false alarms


Security systems may be designed to accommodate indoor pets; however, if you acquire a pet after installation, you may need to have your system modified so pets will not trip indoor motion detectors.


Your system was designed according to the original configuration of your home. False alarms may be caused by significant changes to that layout, even such interior changes as replacing window shutters with drapes, moving large furniture, and installation of fans or air conditioners.


Train all trusted individuals who may visit your home (housekeepers, nannies, maintenance personnel) on proper operation of your alarm system.

Moving Objects

Balloons, large plants, and objects that fall are common causes of false alarms.

Doors & Windows

Be sure to close doors and windows securely, as they may trigger an alarm if blown open.

Bugs, Pests, or Dust on a Sensor Lens

Smoke detectors and motion detectors should be cleaned regularly to prevent false activation.
