Longmont Private Property False Alarm Reduction Program

As the City of Longmont grows, so does the installation and use of home and commercial security alarm systems. Unfortunately, the number of false alarms also increases.

Ninety-eight percent of all alarms are false. Most of these false alarms were caused by user error or inaccurate contact lists provided to the security alarm company by the alarm owner.

Many alarm owners do not realize the contract they sign is with the alarm company, not the police department. The police department responds at the request of the alarm company. Therefore, it is crucial that the alarm owner develops clear instructions for responses to their alarm "with their own alarm company."

Effective October 1, 2005 all Boulder County Law Enforcement Agencies have officially adopted a County-Wide False Alarm Reduction Policy, better known as Enhanced Call Verification. In order for a police response to occur, the alarm businesses must follow the procedures developed by the Central Station Alarm Association, which were approved by the American National Standards Institute (ANSI) for the monitoring and reporting of alarms. This requires multiple calls to separate numbers, in an attempt to verify the validity of the alarm prior to requesting a response from law enforcement.

Therefore, all residential and commercial alarm users must provide at least two telephone numbers to their alarm company to contact before the alarm company contacts the Longmont Emergency Communications Center. It is the responsibility of the alarm owner to update these telephone numbers with their alarm companies.
