Why Should I Have a Security Alarm System?
It is debated whether having an alarm system decreases the chances
of a burglary. In theory, if a burglar is aware a house has a
system, he or she might move on to another home. Even if the alarm
system does not keep a burglar from breaking in, the burglar has a
tendency to stay a shorter amount of time. This may decrease the
number of items stolen and the extent of damage done.
What Should a Security Alarm System Include?
Most systems rely on a combination of contacts placed at doors and
windows and motion sensors. Motion sensors, however, do not detect
someone until they are already in the house. Motion sensors should
NOT be used as the primary means of detection. It is best that all
exterior potential points of entry have contacts that sense when
they are open. Glass break sensors are also available and
recommended.
The basic elements of a standard home security
system include:
- Control
Panel: This is the location where
the system wiring terminates, the backup battery is located,
and where it is connected to the phone lines if it is a
monitored system.
- Keypad:
This is where the system is armed and disarmed. Additional
keypads can be installed. For example, a keypad can be
installed next to the homeowner's bed. If the alarm sounds in
the middle of the night and the security system had the
capability, the keypad display could indicate which door,
window, or motion detector caused the alarm.
- Siren:
A loud siren sounds when there's been a break-in and it also
lets an intruder know they've been detected.
- Inside
Motion Detector: Passive infrared,
microwave, or photoelectric detectors sense changes in a room
caused by human presence. Special motion detectors are
available for people who have pets.
- Door and
Window Contacts: Magnetic contacts
form a circuit between a door and doorframe or a window and a
sill; when the door or window is opened (and the system is
on), the circuit is broken and sounds the alarm.
- A Central
Monitoring Station (Company): If
the system is monitored, in the event of an alarm, the
control panel sends a message over a telephone line to a
central monitoring station, which is manned 24 hours a day.
After attempting to contact the homeowner, the central
monitoring station will contact the police, fire department,
or medics. There is usually a monthly fee for this service.

Additional items that can be added to the basic
system are:
- Smoke
Detectors are required by many
building codes. They can be wired to the security panel. If
the smoke detectors go into alarm, the security panel will
notify the central monitoring station if smoke is detected.
- Glass
Break Detectors recognize the sound
of glass breaking and will sound the alarm.
- Panic
Buttons can be hand-held and should
be located in strategic places such as next to beds and
doors; just punching the button will send a message to the
central monitoring station for help. Homeowners may choose to
have the panic button send the alarm as a silent alarm or
sound the alarms within the house.
- Pressure
Mats can be placed under rugs and
react to pressure from footsteps activating the alarm.
- Closed
circuit TV is a private TV system
which allows monitoring and/or recording inside or outside a
home.
- Alarm
Screens are special screens for
windows that have a special wire woven in the mesh that will
activate an alarm when cut or removed.

Costs
The average system, which includes either motion detectors inside
the house or sensors around windows and doors, costs about $1,200
plus monthly monitoring fees of less than $25. Many security
companies offer the systems for free - in exchange for long-term
monitoring contracts.
Monitored System or Unmonitored System?
Monitored Systems contact a monitoring company by telephone.
The typical sequence of events is as follows:
- The security system
senses something.
- The security system
waits for 30 to 45 seconds before going into alarm allowing
the homeowner a chance to deactivate the system to prevent
false alarms.
- If not deactivated,
the security system goes into alarm and sends a message to
the monitoring company over telephone lines.
- The monitoring
company receives the message, determines the nature of the
alarm and verifies the alarm, generally by placing a phone
call to the home. If they do not receive the proper password
or do not receive an answer, they call the police.
- The police receive
the monitoring company's call and respond.

Caution: A
monitored alarm uses the phone line to call the monitoring company.
If personal safety were at risk when the alarm sounds, a homeowner
would be unable to call 911 or call for help by phone while the
alarm system is communicating through the phone line with the
monitoring company.
The only way to keep this from happening would be to have more
than one telephone line into the house or have a cellular phone
available.
Unmonitored systems typically have on-site alarms and/or
flashing lights that indicate the security system has been
breached. It relies on neighbors as the eyes and ears to see or
hear the alarms and then to call police. Neighbors or passersby
should never investigate an alarm themselves.
With an unmonitored system, it is best to have a combination of
strobe lights and alarms. They should be located on the street side
of the house and in an as-inaccessible spot as possible. Because it
can be difficult to determine the location of a siren, it is best
to discuss this with your neighbors and to place the siren and
flashing light on the house where it can be easily seen.
The advantage of this type of system is that a burglar's primary
goal is to gain entrance to the house, remove property, and do so
without being noticed. Many burglars will leave once alarms and
strobes are activated. The disadvantage to an unmonitored system is
it relies on neighbors who may not be at home or may not want to
become involved. This system is appropriate for a typical suburban
setting but might not work as well for a home out in the country
without close neighbors.
How to Choose an Alarm Company
Choosing an alarm company can be confusing and the technology
complicated. Here are some suggestions:
- Check with friends
or neighbors for recommendations on reliable companies.
- Find out how
quickly the alarm company will install your system after
purchase. See if the company sells systems faster than they
can install them.
- Determine how
quickly they respond to requests for service after
installation. Ask for references from some of their customers
who have required service and call and talk to these people.
- Ask about
warranties.
- Obtain quotes from
at least three different companies.
- Ask the alarm
company what screening they do when hiring their alarm
installers and salespeople. You want a company that screens
for criminal backgrounds/records, etc.
- Call your local
police department and ask how long it takes them to respond
to a home security system alarm. Don't be surprised if the
estimated response time is as long as an hour. Also ask
if there are any fines for false alarms.
- Lastly, when
comparing prices remember to compare detection coverage and
features. The least expensive system could be all you need,
or a waste of money. Not all alarms are created equal.

Here are some
additional suggestions from the Arizona Burglar & Fire Alarm
Association on how to select a security alarm company.
(Most of this information would be applicable to other states that
have similar registrars and licensing requirements.)
- Contact several
companies. Ask if they are members of the state Burglar &
Fire Alarm Association. Most members in these associations
agree to maintain a high level of conduct under state and
national codes of ethics.
- Ask each company if
it is licensed through the state Registrar of Contractors.
Call the Registrar to see if there are any unresolved
outstanding complaints.
- Contact the Better
Business Bureau to find out if any complaints have been filed
against the companies.
- Narrow the field to
three or four companies. Arrange an appointment with each
company when all members of your household will be present.
Be sure to ask for the name of the person who will be calling
on you, and verify his or her identification upon arrival.
- Ask for an
inspection, demonstration and a quotation in writing. Also,
ask for and check references.
- Study each contract
to ensure you know exactly what you are getting. Consider the
merits of leasing vs. buying.

How Do False Alarms Affect Service?
False alarms with security alarm systems are a significant concern.
It is estimated between 95 percent and 99 percent of the alarms
received are false. Because of this, most police departments
require the system, if it alarms remotely by telephone, to first go
through a monitoring company.
To combat the false alarm problem, some police departments are
imposing fines for false alarms after a specified number of false
alarms.
Things to Remember About Security Alarm
Systems
Burglars realize most security systems sound inside the house and
then the alarm is transferred to remote locations through the
telephone lines. Most phone lines are typically exposed on the
outside of the house in an easily accessible location where the
phone line can be cut. If the telephone line is cut, the security
alarm system cannot notify the central monitoring station of the
break-in.
If the phone line is run underground until it is inside the home
(with the main telephone junction box inside the home), the thief
cannot tamper with the telephone line until after he or she has
broken in. Having a protected phone line to your house is a good
idea whether you have a security alarm system or not.
Burglars learn to adapt to security systems. In New Jersey, some
burglars developed a unique break-in method. The burglars would
rattle the windows causing the alarm to sound and then hide in the
bushes, waiting for the police to arrive. Once the police found
nothing and left the location, the burglars would proceed with the
break-in.
The problem with security systems is that they don't necessarily
stop people from breaking in. The security system is only activated
when the burglar has broken into the house. Also, by the time the
intruder is detected and someone responds to the alarm, there could
be enough time for the intruder to remove items and leave. If the
system does not cause visible or audible alarms to flash or sound
at the site, or there is no one nearby to see or hear these site
alarms, the intruder can leave without being seen.
Remember: Security systems do not prevent thieves from
breaking into homes.
A good security plan should include strong window, door, and lock
products; good security habits and lifestyles (for example, always
locking doors at night or when the house is vacant); and natural
surveillance, such as having neighborhood watches.
