Preventing False Alarms

Sonitrol helps prevent false alarms

Why are false alarms a problem? False alarms take police away from real emergencies. This embarrassing situation for you can endanger responding authorities and your community.

  • False alarms make your security system less reliable and credible.
  • False alarms can cost you money! Almost all cities and towns assess costly fines for excessive false alarms.
  • False alarms may make you reluctant to arm your system thus exposing your facility and property to undetected theft and fire.
  • False alarms at night make your responders less productive the next day.

What causes false alarms?

70% of false alarms are caused by user error. Be sure to train anyone who may be using your system, such as employees, cleaning staff or real estate agents. Sonitrol offers free training as long as we monitor your system. Make sure special arrangements are made for guests or repair technicians. Other causes for false alarms include:

  • Noise sources (i.e., compressors and time clocks)
  • Drafts that move plants and curtains
  • Open, unlocked or loose-fitting doors and windows
  • Banners/signs
  • Helium-filled balloons

Before activating your system:

  • Turn off all noise sources - radios, compressors, televisions, printers, etc.

  • Lock all protected doors and windows.
  • Keep banners/signs, balloons and fan heaters away from motion sensor areas.
  • Know how to cancel the alarm if the system activates.

How can I prevent false alarms?

  • Allow Sonitrol technicians to check and service your system regularly. Routine maintenance can help prevent many false alarms from occurring.

  • Notify Sonitrol immediately if you think your system is not working properly.
  • Make sure everyone who uses your security system understands how it works. Anyone who has a key to your facility should know how to operate your system.

What if my alarm goes off accidentally?

  • Determine if there really is a fire or an actual break-in.

  • Don't panic - remember your code.

  • If the alarm was accidental, disarm your system.

  • Carefully press each number of your code. Practice, be prepared to reset.

  • After you've reset the system, call Sonitrol to report the accidental activation.

  • If your Sonitrol system is tying up your phone line, wait several seconds and try again or use an alternate phone.

  • Don't leave your facility until you've spoken with Sonitrol personnel.

Be prepared!

  • Rehearse alarm cancellation with anyone who might use your system.

  • Make sure that anyone with a key to your facility knows how to operate your system.
  • Tell all users who to call when the alarm activates.
  • Keep your Sonitrol system instruction book and phone number handy.
  • Cancel all alarms that don't need emergency response.
Consider the Facts

Over 98% of alarm activations are false alarms. And with each alarm call costing taxpayers in police time and resources, more and more communities are looking for ways to respond to alarms more effectively. Many communities now require verified response—confirmation by an alarm company or an eye witness that an actual intrusion is in progress—before dispatching police.


The average police response time for non-verified alarm activation now exceeds 45 minutes in many communities. The longer the response time, the lower the chances of police stopping an intrusion in progress and apprehending the criminals.


Increasingly sophisticated crimes, including internal theft and fraud, and crimes accompanied by other disasters such as fire or explosions, overtax traditional alarm systems.
