| Components of a Security System |
|
|
|
|
| |
|
 |
|
Control Panel and Digital Dialer
Control Panels are selected depending on
the features required. The number of users
and number of zones are the largest influence
on the panel selected. |
 |
| |
|
|
 |
|
 |
|
Keypads
Keyspads enable you to arm and disarm the
system, display which zones are faulted,
and read the system status in a user friendly
format. |

VIP Module.
With the newly enhanced VISTA Interactive
Phone Module (VIP) you can perform all the
functions of a wall mounted keypad using
any ordinary touchtone phone, from any remote
location. You can check security system
status, arm or disarm your system, even
operate lights and appliances. The VIP's
high quality voice output, with its large
vocabulary, verbally identifies open zones
and prompts you customer to take appropriate
action. |

Ademco Security Watch.
ADEMCO's 5804WATCH lets you offer you cutting-edge
technology in the simplest, most user-friendly
form imaginable. All the great features
of a 5804 four-button wireless key are combined
with the practicality and durability of
a TimexT digital watch. It's no longer necessary
to carry a separate remote keyfob; security
system control is always right at your fingertips.
Simplified operation helps reduce false
alarms and training costs. |

Door and window contacts
Contacts detect a door or window opening,
by opening or closing a switch, or the motion
of a magnet in the door. |
 |
| |
|
|
 |
|
 |
|
Shock Sensors
Shock sensors detect banging or breaking
of glass windows. |

Passive Infrared Motion Detectors
The "motion sensing" feature
on most security systems is a passive system
that detects infrared energy. These sensors
are therefore known as PIR (passive infrared)
detectors or pyroelectric sensors. In order
to make a sensor that can detect a human
being, you need to make the sensor sensitive
to the temperature of a human body. Humans,
having a skin temperature of about 93 degrees
F, radiate infrared energy with a wavelength
between 9 and 10 micrometers. Therefore,
the sensors are typically sensitive in the
range of 8 to 12 micrometers. The detectors
are sensitive to motion, but not to a person
who is standing still. That's because the
electronics package attached to the sensor
is looking for a fairly rapid change in
the amount of infrared energy it is seeing.
When a person walks by, the amount of infrared
energy in the field of view changes rapidly
and is easily detected. You do not want
the sensor detecting slower changes, like
a radiator cooling off.
If you have a burglar alarm with motion
sensors, you may have noticed that the motion
sensors cannot "see" you when
you are outside looking through a window.
That is because glass is not very transparent
to infrared energy. Modern motion detectors
have the ability to be pet immune, which
is to say cats and dogs are free to roam
about the house without setting off the
alarm. Contact us for further details. |

Glass Breakage detectors
Glass breakage detectors listen for the
frequency of breaking glass to trip the
alarm system. One detector covers a larger
area than shock sensors. |

If you're going to pay
for a security alarm, it costs very little
additional to incorporate fire detection
in a system, and that signal can also be
reported to the central station. This provides
protection for the property from fire loss.
Installing a few smoke or heat detectors
in the attic, above fireplace openings,
in garages and shops, and in the kitchen
will significantly enhance the speed and
effectiveness of detection of fire.
Smoke detectors
Smoke detectors detect smoke because inside
there is a light source and a sensor. When
smoke from a fire enters the detector chamber,
the light is scattered onto the detector
and this signals the alarm. |

Carbon Monoxide detectors
Carbon monoxide (CO) is a deadly gas that
is produced by combustion. It is odorless
and colorless, so it's victims do not realize
they are being suffocated. Typical sources
of CO in the home are gas furnaces, boilers,
and gas fired appliances. Also cars parked
in indoor garages can be a source of CO.
CO detectors will alert the central station
who can then summon help. Central station
intervention is critical since the victims
of CO poisoning are often unable to help
themself.
The above list is a basic overview of typical
electronic security equipment. Your Consumers
Security Group consultant will survey your
home and select the proper equipment for
your needs. |
