FALSE ALARM REDUCTION PROGRAM
ANNUAL REPORT
FOR YEAR ENDING 2000
False Alarm Reduction
The False Alarm Reduction Unit (FARU) of the Montgomery County Department of Police completed its fifth year of enforcement under the amended Chapter 3A, Alarms, of the Montgomery County Code. In calendar year 2000, the FARU exceeded several of its goals for the year, as well as maintained false alarm dispatch rates, even with an increase of almost 8,000 newly registered alarm sites.
The false alarm dispatch rate is perhaps the truest measure of false alarm reduction, as it calculates the number of false alarm dispatches relevant to the total number of alarm users. The false alarm dispatch rate is the only rate, which takes into account the growth of the alarm user base. Montgomery County has the lowest residential false alarm dispatch rate of any jurisdiction in the country at .32. This means that overall, residential alarm users experience, on average, only 1 false alarm every three years, which is a remarkable statistic. The commercial false alarm dispatch rate is 1.09, a slight increase over 1999. Combined residential and commercial false alarm dispatch rates remained at .44, and is one of lowest combined reported dispatch rates in the entire country.

Reported false alarm dispatch rates are as high as 4.0, which means that every alarm user has four actual responses every year. If Montgomery County’s false alarm dispatch rate was 4.0 instead of its current .32, it would mean that police officers would respond to 245,336 alarm activations each year. That would require 79 police officers to do absolutely nothing but respond to burglar alarms at a staggering cost of approximately $12,000,000.
In projecting the number of alarm activations to which police would have responded in 2000, absent any enforcement of the alarm statute, statistics show that police officers would have actually responded to 87,707 alarm activations instead of 26,877. This number assumes that the 1.43 dispatch rate present in 1994 would remain constant through and including 2000, which is highly unlikely. A more accurate assumption would be that, absent any enforcement of the amended alarm law, the dispatch rate would continue to rise each year, and the number of actual responses in 2000 would be more than 150,000. This projection clearly shows just how significant the .44 dispatch rate and the 26,877 (as opposed to over 150,000) actual responses to alarm activations in 2000 really are. Estimated costs to respond to 150,000 alarm calls would be $7,500,000; clearly a cost that no local jurisdiction can absorb.
Since enforcement of the alarm law began in 1995, alarm activations to which police officers must respond has been reduced by a total of 37.2%. Despite a growth in alarm users of 31,578, police responded to almost 16,000 less alarm calls in 2000 over 1994. Actual responses to alarm calls between 1999 and 2000 rose slightly.

In reviewing Graph 1 above, it reveals that requests for dispatch continue to rise, as do the total number of alarm users in Montgomery County. Absent enforcement of the alarm statute, coupled with the increase in alarm users, one would expect that the actual dispatches to alarm activations would increase substantially, or at least as the same rate of growth. However, actual responses to alarm activations increased by a mere 1.4% between 1999 and 2000. Chart 11 on page 15 and Chart 12 on page 16 indicate that the increase in false alarms occurred most often in commercial locations. Statistical analysis of the commercial false alarms indicate that banks are a major contributor to the false alarms in Montgomery County, yet account for a very low percentage of the total number of commercial alarm users. The FARU will be focusing on bank facilities in the coming year, looking at any unique security needs, problems and/or circumstances, which may contribute to their false alarm problems.
Graph 1 also shows that the County continues to maintain a reduction relative to the total number of requests for dispatch vs. the total number of alarm users. For example, in 1994, Montgomery County police officers responded on 97.5% of all requests for dispatch (43,936 requests for dispatch with 42,821 actual responses). However, in 2000, police officers responded on only 55.3% of all requests for dispatch (48,603 requests for dispatch with only 26,877 actual responses). This represents a 42.2% reduction between requests and dispatches, even with 31,578 more alarm users, and correlates to significant savings in police officer time.
Graph 2 and Chart 2 below depict the difference between the requests for dispatch and the actual responses since 1994. While there was a slight increase (1.4%) in the percentage of total calls responded to between 1999 and 2000, the number of requests for dispatch and the total number of alarm users increased as well, which makes this slight increase less significant.

One critical timesaving measure in the alarm statute is the requirement that an alarm company cancel a police response when it is determined that an alarm activation is false. The high number of non-responses was due, in part, to that required cancellation by alarm companies. The higher the number of cancellations, the better the job the alarm companies are doing of reducing the number of false alarms to which police officers are required to respond. In 2000 alarm companies cancelled 7,424 requests for dispatch, an increase of more than 200 cancellations from 1999. These cancellations provided officers with more time to engage in other law enforcement related activities.
The FARU continued its strict enforcement of all requirements for requesting dispatch, including providing the correct alarm user registration and alarm business license numbers. Police officers were not dispatched when an alarm business failed to provide all of the required information to ECC calltakers. Nor were police dispatched if an alarm user was in a violation status for failure to register, failure to pay a false alarm response fee, or failure to upgrade the system to meet county installation standards. The legally mandated non-response provisions in the alarm law resulted in 3,282 requests for dispatch that were denied as a result of the violation status of the alarm user or alarm business. It is significant that this number is down from 3,651 in 1999, which represents a full 369 fewer requests for dispatch that were in violation of the statute. This is directly attributable to the FARU’s enforcement initiative in 2000 that cited alarm businesses that were illegally requesting dispatch. (See Major Accomplishments on page 10 for further information on this initiative.)
In 2000, almost 7% more residential and commercial alarm users experienced no false alarms at all. A total of 45,684 alarm users had zero false alarm activations in 2000. As the following pie graphs show, each year, more alarm users achieve the zero false alarm threshold. This statistic, which is supported by the low false dispatch rate, is indicative of the success of the overall false alarm reduction program. These reductions become more significant when viewed with the steady increase in the number of alarm users each year.

As a direct result of the FARU’s strict enforcement of the alarm legislation, there were 20,172 alarm calls to which police officers were not required to respond in 2000. This equates to savings in 2000 of approximately $1,008,600 and 13,448 hours of police officer time, or 6.47 police work years. (Monetary savings are based on a conservative cost of $50.00 per response. Work year savings are based on an average of 20 minutes per alarm response by two officers.) This timesaving allows police officers more time to engage in proactive crime prevention efforts, neighborhood patrol, and community policing initiatives.
The following graphs illustrate the revenues, hours, and work years saved as a result of the false alarm reduction program.

Graph 3 shows that the actual revenue saved in 2000 as a result of police officers responding to 20,172 less false alarms was $1,008,600. Since the FARU began enforcement of the alarm statute, the total revenue saved by Montgomery County has been $4,442,050.

Graph 4 shows that the actual hours saved in 2000 as a result of police officers responding to 20,172 less false alarms was l3,448 hours. Since the FARU began enforcement of the alarm statute, Montgomery County has recovered 59,215 hours in police officer time.

Graph 5 shows that 6.47 actual work years were saved in 2000 as a result of enforcement of the alarm statute. Since enforcement began, Montgomery County has recovered a total of 28.47 work years of police officer time.
The total savings in dollars, hours, and work years since 1994 have been significant, and are depicted in Chart 3 below. As stated previously in this report, absent strict enforcement of the alarm statute, Montgomery County would have paid more than $5,000,000 in 2000 alone responding to false alarms. The $4,442,050 savings to the county is, therefore, even more significant.

In calendar year 2000, the FARU had 459 registered government facilities, all of which were held to the same strict standards as all other alarm users. Of the 459 government alarm users, 104, or 23%, had a least one false alarm. This is down from 113, or 25.4%, government alarm users in 1999. Those 104 alarm users collectively had 213 false alarms. The good news for government alarm users is that 355, or 77%, had zero false alarms in 2000. This percentage is slightly better than the percentages shown for all other alarm users (74.5%). The following chart reflects government alarm user activity for 1999 and 2000.

Revenue
The following two charts reflect revenue collected by the FARU for alarm user registration fees, false alarm response fees, alarm business license fees, civil citations, and appeal filing fees. The first chart covers calendar year 2000. The second chart covers fiscal year 00. The FY00 chart is included only as a reference, because budget projections are based on fiscal rather than calendar years. The more accurate chart is the calendar year 2000 chart, as false alarms and the resultant false alarm response fees are calculated on a calendar year basis.

Collection of false alarm response fees is always a priority for the FARU, as it shows alarm users that Montgomery County is serious about false alarms and does, in fact, enforce its alarm statute. The FARU’s collection rate in 2000 was 81.5 % of all false alarm response fees billed. The suspension of police response provision in Chapter 3A, Alarms, for failure to remit false alarm response fees greatly enhances the FARU’s ability to collect on unpaid bills.
The following chart reflects the amount billed for false alarm response fees versus the amount collected for both residential and commercial alarm users. Please note that the “collected” amount in the following chart reflects payments made against false alarms that occurred in 2000. The actual collection of monies for those calendar year 2000 false alarms extended into calendar year 2001, and, therefore, reflects more revenue than was actually received in 2000.

Major
Accomplishments
Enforcement
One of the FARU’s main goals in calendar year 2000 was to increase enforcement of the alarm law with relation to alarm companies. To that end, our goal was to issue 200 Class A civil citations to alarm companies for violation of Chapter 3A, Alarms. The intent of this initiative was for alarm companies to change their behavior and become more responsible and compliant with the mandates of the law.
The FARU exceeded its goal by 72, issuing an impressive 272 Class A ($500) civil citations to 72 different alarm companies for violation of the alarm law. Most violations involved requesting dispatch on alarm users who were in a non-response status, requesting dispatch without providing the alarm user’s registration number, and requesting dispatch when the alarm company was not licensed or had an expired license.
The initiative proved very successful in changing behavior, as well as obtaining better compliance with the law. In January 2000, the FARU wrote 52 Class A civil citations, yet in January 2001, only 7 were necessary. The enforcement initiative implemented in 2000 will continue as a regular part of the false alarm reduction program.
The FARU was successful in denying the issuance of an Alarm Business License to an individual, who had prior criminal offenses, and who misrepresented those convictions on the Alarm Business License application.
The FARU initially denied the request for a license and offered the applicant an opportunity to show cause why the license should be granted. A hearing was set before the Montgomery County Hearing Officer to hear testimony from both the applicant and the County. While the applicant received proper notice of the hearing, the applicant failed to appear at said hearing. The County presented its case against the applicant, and the Hearing Officer ruled, in part, that:
1. criminal convictions against the applicant occurred within the prescribed 7-year period outlined in Chapter 3A, Alarms,
2. the applicant falsely stated on the application for an Alarm Business License that the applicant had not been convicted of “any felony or a misdemeanor involving theft,” and
3. based on the falsification of information on the application, the license should not be granted.
The Major Offender Program implemented in 1999 by the FARU, was designed to identify those alarm users who have the highest number of false alarms and to then meet with them, their alarm companies and patrol officers in an effort to determine the cause(s) of and appropriate solutions to their false alarm problems.
The FARU’s goal in 2000 was to reach 15 different alarm users. Far exceeding that goal, in calendar year 2000, the FARU identified and worked with 50 different alarm users, who were experiencing false alarm problems. The FARU’s supportive intervention resulted in very positive outcomes for 45 of the original 50 alarm users. Specific problem areas were identified in all cases and the alarm users and their alarm companies took corrective action. Of the 5 accounts that did not show positive results, 4 were banks. The FARU plans to focus more closely on banks in general in calendar year 2001 to identify specific, unique issues inherent in a bank environment and to develop a plan of action to address their problem false alarms.
The FARU moved into the 21st century and started to get its message out via the world wide web. Visitors to the FARU site, located at http://www.montgomerycountymd.gov/services/police/faru, receive background information on the need for false alarm reduction legislation and enforcement, an overview of the alarm law and how it works, false alarm reduction tips, information for consumers on what to look for when purchasing an alarm system and the pertinent questions to ask, as well as copies of the FARU annual reports, among other things. The web site is a work in progress and will continue to be updated and added to throughout the year. The FARU is currently working on redesigning the page to make navigation easier and more meaningful for users.
When an alarm user fails to pay a false alarm response fee, the FARU advises the alarm user’s alarm company that it may no longer request dispatch for that user and refers the account to the Office of the County Attorney for collection action. In 2000, the FARU referred 344 different alarm user accounts to the Office of the County Attorney for collection of outstanding/
delinquent fees that totaled $74,760.
Montgomery County’s alarm law has long been a benchmark that other jurisdictions try to attain. In the spirit of cooperative working relationships with our area cities and counties, the FARU staff spent considerable time with area law enforcement officials assisting them in
their attempts to enact false alarm reduction legislation. The FARU helped Frederick, Howard and Fairfax Counties, as well as Baltimore City, enact new alarm laws. Additionally, FARU staff assisted Arlington and Harford Counties in their efforts to pass false alarm reduction legislation. Finally, ongoing contact is maintained with Prince George’s, Charles, and Baltimore Counties, as well as those mentioned above, to answer procedural and policy questions, act as a sounding board for new ideas, and provide assistance with unusual circumstances or situations that arise.
Due to the wide exposure of Montgomery County’s alarm law, as well as the national association of law enforcement officials created by the FARU’s director, FARU staff sit on several alarm industry boards and committees to offer advice from a law enforcement perspective, develop initiatives to reduce false alarms at a national level, and maintain good working relationships between law enforcement and the industry.
The FARU director was appointed as a law enforcement representative and a voting member of the National Burglar and Fire Alarm Association’s False Alarm Committee. Past successes of the FAC include development and implementation of the “False Alarm Network.” The FAN is a network of industry, national company, and law enforcement representatives, who work closely in most states to inform interested parties of the enactment of new laws, the development of new alarm equipment, and the dissemination of proven false alarm reduction methods and techniques. The False Alarm Committee develops programs for false alarm reduction on a national level. Additionally, the FARU director is a member of the IQ Certification Board, which is an industry program that seeks to raise the bar on the quality of alarm system installations in terms of equipment used, how it is installed, and the level of training needed for alarm technicians. Participation in committees like these help keep Montgomery County in the forefront of false alarm reduction efforts.
The first point of contact with the Police Department when attempting to request dispatch to an alarm activation is with the Emergency Communications Center. While police officers only responded to 26,877 requests for dispatch, the ECC call-takers and dispatchers handled all 48,603 attempts to dispatch. It is critical that ECC personnel obtain specific training to handle these types of calls. Over the past year, the FARU staff have provided specialized training to new ECC recruits as part of their overall training for the position. The training includes an overview of the alarm law and executive regulation, why the law and regulation were enacted, the scope of the problem, ECC and FARU SOP’s, review of actual calls and what was done correctly or incorrectly, and discussion of the successes of the false alarm reduction program. The FARU is grateful to ECC training supervisors for including them in the training of new recruits, as it provides for more seamless program operation.
General Statistics
Chart 8 shows false alarm reduction statistics from 1994, when the new alarm law was in effect but false alarm response fees were not yet being imposed, through 2000. The chart shows the actual number of requests for dispatch, the number of calls that were ultimately dispatched and responded to, requests where no response was required or was refused, verified calls and the percentage of false alarm reduction. Circumstances under which no response may occur include cancellation of response by the alarm company, duplicate calls for the same location, blanket cancellations by supervisory police personnel, and refusals where the alarm company or alarm user was in a violation status.

Chart 9 reflects the number of alarm users each year since 1994. Alarm user registrations have more than doubled since implementation and enforcement of the false alarm reduction program began in 1994. On average, the FARU receives 8,000 new alarm user registrations each year. (The chart below does not reflect an increase of overall alarm users of 8,000 because some users each year move out of the area or remove their alarm systems and are no longer required to have an alarm user registration.) This increase coupled with the 37.2% decrease in alarm activations to which police officers must respond each year is truly remarkable. The success and results of this program are what make it a model for other municipalities across the country.

The following charts depict the number of alarm users that had a specific number of false alarms from 1995 through 2000 and the percentage of change from year to year and from the base year of 1995. Chart 10 shows residential alarm users. Chart 11 shows commercial alarm users, and Chart 12 reflects total alarms (both residential and commercial combined.)
As stated earlier in this report, each year an increasing number of alarm users have no false alarms at all. In 2000, 45,684 alarm users had ZERO false alarms to which police officers were required to respond. This is up from 42,800 in 1999. Therefore, the most compelling statistic in these charts is in the number of alarm users that appear on the 0 row (meaning they have had no false alarms for the entire calendar year).
