Alarm Ordinance Permits

Alarm Ordinance

The Clackamas County alarm ordinance (Chapter 8.07 of the Clackamas County Code) was enacted to help reduce the number of false alarms that the Clackamas County Sheriff's Office receives. Currently, over 98% of all burglary and robbery alarms prove false. Sheriff's patrol units are dispatched to all alarms. The hours and resources used during responses to unfounded false alarms is a burden on resources.

Neighboring counties and cities utilizing similar alarm ordinances have experienced greatly reduced numbers of false alarms within their jurisdictions. This results in patrol officers being more available to meet other requests for service. With limited revenues, increasing county populations, and only a limited number of deputies, it is important that the deputies and resources of the Sheriff's Office be allocated to their best use.

We expect the Alarm Ordinance to help us make more efficient use of our deputies and provide more timely law-enforcement service to county citizens.

What is a False Alarm?

The Clackamas County Alarm Ordinance defines a false alarm as "an alarm signal eliciting a response by emergency services when a situation requiring a response does not in fact exist."

Common Causes of False Alarms


  • Inadequate training of all those allowed access to your alarm system
  • Domestic help, house cleaners, contractors, realtors, lawn care workers, extended family members and pet sitters
  • Weak or depleted system batteries. Usual battery life is about 3-5 years.
  • Open, unlocked, loose fitting or defective doors/windows.
  • Drafts from heaters/air conditioning systems and open windows move plants, curtains, balloons etc.
  • Wandering unconfined pets
  • Barking dogs can activate "glass break" detectors


  • Banners or signs and seasonal decorations
  • Cleaning crews
  • Mylar balloons
  • Plants or curtains caught in drafts
  • Stacked items such as boxes that may fall, setting off motion detectors.
  • Unsupervised guests.

What To Do If You Set Your Alarm Off Accidentally

  • First, don't panic. Carefully disarm your system by entering your cancellation code slowly.
  • Wait for your alarm company or central monitoring station to call, give your password. If the correct password is not given, the monitoring company will inform you that the alarm will be canceled, but they will then call dispatch to advise that the improper password was given. Make sure you know your password!
  • Do not leave your home or business until you have talked with your monitoring station! DO NOT call 911 to cancel an alarm activation.

False Alarm Prevention Tips


  • Lock all doors and windows before activating your alarm system.
  • Keep pets, balloons, fans, heaters, plants, curtains, seasonal decorations, etc. away from motion sensor areas.
  • Ensure that there are no cobwebs or insects that could set off your system's motion detectors. If a spider or bug gets on the face of the motion detector, it can cause a false alarm.
  • Educate all alarm system users and responders
    • Train them how to operate your system
    • All users should know the correct arming codes, pass codes, monitoring company phone number and procedure for canceling accidental alarm activations. If you give someone your key-train them to operate your alarm.
  • Schedule a service call if the alarm is not working properly. Routine maintenance can help prevent many false alarms.
  • Have the alarm battery changed every 3-5 years. They typically last about 4 hours in the event of a power outage. The life of the battery is shortened if you have had several power outages.
  • Notify your security company if you install DSL, VoIP, FIOS or intercoms.


  • Fully train new system users. Hold monthly training sessions to teach proper operation and how to cancel accidental activations.
  • Thoroughly train temporary holiday employees to avoid holiday-related false alarms.
  • Look for items that can move within the "view" of your motion detectors, causing false alarms.
  • Ensure that floor mounted contacts are not being used on overhead/rollup doors. Track-mounted wide gap contacts on BOTH sides of the door should be used instead; BOTH contacts must be activated before an alarm is triggered.
  • Don't change pass codes and/or arming codes without advising your authorized users. If a pass code is changed notify your alarm company.
