False Alarm Reduction
The False
Alarm Reduction Section (FARS) of the Montgomery County Department of
Police completed its ninth year of enforcement under the amended
Chapter 3A, Alarms, of the Montgomery County Code. The FARS
reports that there was a dramatic decrease in the incidence of false
alarms between 2003 and 2004, despite an increase of 6,575 new alarm
users. The FARS also performed outreach to approximately 34 different
problem accounts in its “Major Offender” program, successfully
completed the first full cycle of alarm user renewals, updated its web
site, performed numerous outreach to the community and continued to
reduce false alarm dispatch rates for alarm users.
In
calendar year 2004, false alarms to which police officers were
required to respond were reduced by 10.5% over the previous year. The
FARS now shows a full 55.2% reduction in false alarms since
enforcement of the False Alarm Reduction Program began in earnest in
March 1995. Additionally, police officers responded to 23,631
less alarm calls in 2004 over 1994. These statistics, coupled
with a 114% increase in the number of registered alarm users over the
same time period, clearly shows that substantial false alarm reduction
is still being achieved and that the alarm law is an excellent tool in
reducing false alarms and positively changing alarm user and alarm
business behavior. It is also a testament to a well-written,
enforceable law and a highly dedicated and talented FARS staff.

Graph 1 – False Alarm Reduction,
provides information on the number of requests for dispatch vs.
actual responses (dispatched). If the false alarm reduction
program is successful, the responses should continue to decrease
relative to the number of total alarm users, and this fact is evident
in the graph. The graph also provides information on calls where no
response was made, as well as the total number of alarm users. The
number of actual alarm calls to which police officers respond has
continued to decrease. Police responded to only 19,190 of the total
38,248 requests made, or 49.8%. There were a total of 17,492 alarm
activations to which the police were not required to respond in 2004.
Additionally, the number of requests for dispatch
is at an all-time low. In 2004, there were a total of 38,248 requests
for dispatch to alarm activations, down by a staggering 6,425 over the
previous year. Requests for dispatch remained fairly static between
1994 and 2003 and results were measured in how many less
responses police officers were required to make. While this is still
the most important measure of the success of the program, 2004 marked
a huge decrease in the number of requests for dispatch, which has
far-reaching benefits for the Police Department beyond savings
measured in police officer time. Less actual alarm calls into our
Emergency Communications Center means time recovered for Police
Telecommunicators to handle other requests for service from Montgomery
County citizens. This is an extremely positive measure, which is
directly attributable to the alarm industry’s Enhanced Call
Verification (ECV) initiative.
Chapter 3A, Alarms, of the Montgomery County Code
requires alarm companies to attempt to verify the validity of an alarm
signal prior to requesting police dispatch. This attempted
verification generally requires one telephone call be made to the site
to determine the cause of the alarm signal. The alarm industry has
instituted Enhanced Call Verification in which alarm companies make
the initial call to the site, and if unable to reach a responsible
party, make at least one additional telephone call to another phone
number, usually the customer’s cell phone. This voluntary initiative
has dramatically reduced the number of requests for dispatch made to
9-1-1 centers across the nation. The alarm industry, and those alarm
companies that have voluntarily enacted ECV within their own
companies, should be congratulated on developing and implementing a
false alarm reduction strategy, which has dramatically reduced false
alarms.
Absent enforcement of the alarm statute, coupled with an
overall increase in alarm users, one would expect that the actual
dispatches to alarm activations would increase substantially, or at
least at the same rate of growth. However, actual responses to
alarm activations were reduced by an additional 10.5% between 2003 and
2004.
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 2004, police officers responded to only
49.8% of all requests for dispatch (38,248 requests for dispatch with
only 19,190 actual responses). This represents a 50.2% reduction
between requests and dispatches, even with 33,992 more
alarm users and correlates to a significant savings in police officer
time.
One critical enforcement 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. This is achieved
through telephone or other electronic verification with the alarm user
at the time of alarm system activation. The high number of
non-responses (17,492) 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 respond. In 2004, alarm
companies cancelled a very impressive 9,028 requests for dispatch,
which represents 24% of the total requests for dispatch. These
cancellations provide officers with more time to engage in other more
critical law enforcement related activities and community policing
initiatives.
The FARS also 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 Emergency Communications Center
call-takers. 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 alarm system when required to
do so. The legally mandated non-response provisions of the alarm law
resulted in only 2,258 requests for dispatch that were denied as a
result of the violation status of the alarm user or alarm business.
This represents only 6% of the total requests for dispatch. The FARS
will continue to work to reduce this percentage to negligible
numbers.
Graph 2 and Chart
1 – Requests for Dispatch vs. Actual Responses depict the
difference between the requests for dispatch and the actual responses
since 1994. As stated previously, requests for dispatch in 2004
declined by a significant 6,425 calls, while the actual responses
(19,190) to requests fell below 20,000 for the first time since
statistics were captured. This, coupled with 6, 575 new alarm users,
is incredibly positive and demonstrates the effectiveness of
Montgomery County’s alarm law.

The false alarm dispatch rate is perhaps
the truest measure of false alarm reduction, as it calculates the
number of false alarm dispatches relative 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. The Security
Industry Alarm Coalition (SIAC), which represents the four major alarm
industry associations in North America, states that Montgomery County
has the lowest reported residential, commercial and combined false
alarm dispatch rates of any jurisdiction in the country. The
residential false alarm dispatch rate decreased once again in 2004 and
was .21. This means that overall, residential alarm users experience
less than one false alarm every four years, which is a remarkable
statistic. The commercial false alarm dispatch rate for 2004 was .89,
which marks a negligible 1/100% increase over 2003 levels, but still
reflects four years running that the commercial rate was well below
the 1.0 mark. Combined residential and commercial false alarm
dispatch rates fell to an all-time low of .30 and is the lowest
combined reported dispatch rate in the entire country.

Nationwide statistics often reveal
reduction in false alarms for the first several years after enactment
and enforcement of a false alarm reduction ordinance begins. However,
after the first few years, the numbers generally either level off with
no further reduction or actually start to increase. Since the
Montgomery County false alarm reduction program has been in effect, it
has consistently reduced the false alarm dispatch rate (with the
exception of 2000, which remained constant) and has done so for a full
nine years. Few, if any, other jurisdictions can boast such a
phenomenal success rate.
Commercial false alarm dispatch rates have been reported
as high as 4.0 and residential false alarm dispatch rates as high as
1.0 or above. A dispatch rate of 4.0 means that every alarm
user has four actual responses every year. Using 2004
statistics, that would equate to 35,152 actual responses to alarm
activations for commercial alarm users alone; a figure
almost 16,000 over the total responses for residential and
commercial alarm users combined in 2004.
Assuming Montgomery County’s dispatch rate would have
risen a modest amount to 2.0 without enforcement of the alarm law,
police officers would have actually responded to 127,496 false alarm
activations in 2004, which would represent a 564% increase in
response to false alarms. At $90 per dispatch, those 127,496 alarm
activations would require approximately 41 police officers to do
absolutely nothing but respond to burglar alarms at a staggering cost
of $11,474,640. This is clearly a cost that no local jurisdiction can
absorb. The
following pie charts (Graphs 3, 4 and 5) graphically depict the
significant reductions in residential, non-residential and combined
false alarm dispatch rates.
In 2004, an impressive 80.7% of all
residential and commercial alarm users experienced no false alarms at
all. A total of 51,454 alarm users, had zero false alarm
activations to which police officers responded in 2004. The
following pie graphs show that each year more alarm users (as a
percentage of total alarm users for a given year) 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 FARS’s strict
enforcement of the alarm law, there were 17,492 alarm calls to which
police officers were not required to respond in 2004. This equates
to savings in 2004 of approximately $1,574,280 and 12,794 hours of
police officer time, or 12.30 police work years. (Monetary
savings are based on a cost of $90 per response. Work year savings
are based on an average of 20 minutes per alarm response by two
officers.) This timesaving is substantial, particularly when the
department is being asked to do more with less each year.
The following graphs illustrate the revenues, hours and work years
saved as a result of the false alarm reduction program.
|
|
Graph 6
shows that the actual revenue saved in 2004 as a result of police
officers responding to 17,492 less false alarms was $1,574,280.
Since the FARS began enforcement of the alarm statute, the total
revenue saved by Montgomery County has been $10,887,310.
(The dramatic difference in 2002
savings and subsequent years is due to using a more realistic
figure of $90 per response, as opposed to $55 in 2001 and $50 for
previous years.) |
 |
 |
Graph 7
shows that the actual hours saved in 2004 as a result of police
officers responding to 17,492 less false alarms was 12,794 hours.
Since the FARS began enforcement of the alarm statute, Montgomery
County has recovered 113,037 hours in police officer time. |
|
Graph 8
shows that 12.30 actual work years were saved in 2004 as a result
of enforcement of the alarm statute. Since enforcement began,
Montgomery County has recovered a total of 74.12 work years of
police officer time.
(The dramatic difference starting in
2002 vs. previous years is due to erroneously using a full 2080
hours as a work year measure between 1994 and 2001, which is not
an accurate figure.) |
 |
|
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 $11,000,000 in 2004 alone responding
to false alarms. The $10,887,310 savings to the county is,
therefore, even more significant.

In calendar year 2004, the FARS had 515 registered federal, state and
local government facilities, all of which were held to the same strict
standards as all other alarm users. Of the 515 government alarm
users, 161 or 31.3%, had at least one false alarm. This shows an
increase of 11.3% over 2003. Those 161 alarm users collectively
had 318 false alarms. A total of 354 different government alarm
users (68.8%) had zero false alarms, which is down from a high
of 400 in 2003.
As is evident in Chart 4 – Government Alarm Users, false alarms in
government facilities rose fairly dramatically in 2004. Some of
this increase is due to the registration of certain federal
facilities, which are currently learning about the costs of false
alarms, both in terms of dollars spent and in officer safety issues .
FARS staff will work more closely with all government alarm users in
the coming year to effect reduction in police responses to those
alarms. The following chart reflects government alarm user
activity for 1999 through 2004.

Revenue
The
following two charts reflect revenue collected by the FARS for alarm
user registration and renewal fees, false alarm response fees, alarm
business license and administrative fees, civil citations and appeal
filing fees. The first chart covers calendar year 2004.
The second chart covers fiscal year 04. The FY04 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 2004 chart, as false alarms and the resultant false
alarm response fees, are calculated on a calendar year basis.

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 2004. 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. Verified calls include actual criminal activity, as
well as suspicious situations such as an open door with no other
evidence of criminal activity. Circumstances under which no response
may occur include cancellation of response by the alarm company,
duplicate calls for the same alarm activation, 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. The
FARS received 6,575 new alarm user registration forms in 2004. This
increase, coupled with the 55.2% 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.

Chart
9 does not reflect an increase of overall alarm users by 6,575 (the
number of new registered alarm users), because some alarm users each
year move out of the area or remove their alarm systems and are no
longer required to have an alarm user registration. Additionally,
with alarm user registration renewal, the FARS is much better able to
keep the alarm user database current by removing those alarm users,
who no longer have an alarm system or have moved. This allows the
FARS to perform statistical analysis using more accurate numbers,
which provides for more meaningful and accurate reporting.
The following charts depict the number of alarm users that had a
specific number of false alarms from 1995 through 2004. The
charts also show the percentage of change between 2003 vs. 2004, as
well as the percentage of change between the base year of 1995 and
2004, which shows the reduction of false alarms since inception of the
program. Chart 10 shows residential alarm users. Chart 11
shows commercial alarm users, and Chart 12 reflects total alarms (both
residential and commercial combined.)
In
2004, 51,454 alarm users had ZERO false alarms to which police
officers were required to respond. This represents 80.7% of all
alarm users, which is up from 2003 statistics where 79.4 alarm users
had zero false alarms. 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).
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 2004. 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. Verified calls include actual criminal activity, as
well as suspicious situations such as an open door with no other
evidence of criminal activity. Circumstances under which no response
may occur include cancellation of response by the alarm company,
duplicate calls for the same alarm activation, 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. The
FARS received 6,575 new alarm user registration forms in 2004. This
increase, coupled with the 55.2% 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.

Chart
9 does not reflect an increase of overall alarm users by 6,575 (the
number of new registered alarm users), because some alarm users each
year move out of the area or remove their alarm systems and are no
longer required to have an alarm user registration. Additionally,
with alarm user registration renewal, the FARS is much better able to
keep the alarm user database current by removing those alarm users,
who no longer have an alarm system or have moved. This allows the
FARS to perform statistical analysis using more accurate numbers,
which provides for more meaningful and accurate reporting.
The
following charts depict the number of alarm users that had a specific
number of false alarms from 1995 through 2004. The charts also show
the percentage of change between 2003 vs. 2004, as well as the
percentage of change between the base year of 1995 and 2004, which
shows the reduction of false alarms since inception of the program.
Chart 10 shows residential alarm users. Chart 11 shows commercial
alarm users, and Chart 12 reflects total alarms (both residential and
commercial combined.)
In
2004, 51,454 alarm users had ZERO false alarms to which police
officers were required to respond. This represents 80.7% of all
alarm users, which is up from 2003 statistics where 79.4 alarm users
had zero false alarms. 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).
