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.

 
 
Zones of Detection.
   

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.

 
 
Fire Detection.
   

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.
