Well it has been crawling into our national contiousness for decades. What's that you say? Most home owners know about security systems for residential homes, but fewer know about home automation systems and exactly how they might fit into a new or remodeled home. To be honest, any home automation system destined for the residential and small business market that is worth it's salt will have a UL approved security system as part of the package.
Everyone who knows me or has followed my informational articles knows that when I install a security system it is normally one that is powerful enough to also provide home automation capability. But this time I want to put out as much information about the security components of a truly modern system as I can.
What is a Security System?
There are not many people who are not at least familiar with a burglar alarm system even if they have not actually been the individual arming and disarming the security system on a day-to-day basis. Most of us realize that a security system consist of a main electronic controller which is normally mounted in a closet or perhaps in the garage. The system is connected to a telephone line so that it can call out to a monitoring company in case of a burglary or [url=http://www.rtnagel.com/louboutin.php]louboutin pas cher[/url] fire. And of course all types of security devices are linked to this security controller which when violated cause the security system to go into the ALARM mode.
Back-Up Power
One of the questions asked of me again and again is, "What happens if the power goes out?" The answer is that all security systems have a 12Vdc battery to provide back-up power [url=http://www.maximoupgrade.com/hot.php]hollister[/url] during a power outage for whatever reason. Some installers double up on the number of batteries to provide additional time in case the power is out for awhile. With the power required for sirens, color touch screens, powered security devices as well as multiple security keypads, the norm is about thirty minutes of additional operational time before the security system goes dead. If however, the reason [url=http://www.getconversational.com]hollister pas cher[/url] for the power failure is that a bad guy cut off your house power, there is more than enough operational time to call out to the monitoring company.
Keep in mind that power in the range of 56Vac is provided continually on the line by the telephone company even though the electrical grid is down. What most people do not realize is that if they have elected to have their telephone service provided as an add-on by their local cable company, when the power goes out so does the telephone.
The Telephone Line
The telephone service, which comes into the house [url=http://www.achbanker.com/home.php]www.achbanker.com/home.php[/url] from the outside world, is first connected to a device known as a RJ-31X. This gizmo is also where the security system ties in to get its connection to the outside when an incident occationally takes place. It allows the telephone line to be seized anytime. The end result is that if you are involved in a great conversation with one of your friends or relatives during a time when an alarm happens, you will be cut off right in the middle of your conversation as the RJ-31X will allow the security controller to call out on the telephone line.
Police and Fire Departments
Everybody knows that if an alarm system has been armed in the AWAY mode and a burglar intrudes a given home, the [url=http://www.maximoupgrade.com/hot.php]hollister france[/url] secutrity alarm will go into the alarm mode. What many consumers do not know is that if a home owner is wise enough to install monitored smoke detectors, that the system will also call out to the fire department as well. This feature can and certainly has saved lives. Many times people do not wake up during a fire until it is too late as they are rendered unconscious by the toxic smoke generated during the fire. When you have [url=http://www.mquin.com/giuseppezanotti.php]giuseppe zanotti pas cher[/url] a monitored smoke detector the fire department is called and will respond to your fire alarm. The next thing one realizes is that they are being awakened and rescued by firemen. The same cannot be said about standard smoke sensors mounted by an technician or purchased at Home Depot.
Security Devices
There are many types of security devices used in a alarm. The most commonly used device is a magnetic contact installed in windows and doors. They don't require electrical power, however they [url=http://www.ilyav.com/uggpascher.php]ugg pas cher[/url] will notify the security controller when a window or door is opened.
Motion Detector
The second most popular device is the powered motion detector. There are two wires which provide 12Vdc power to the device and two wires which are interconnected directly to one of the security zones on the alarm controller. These days there are two technologies at work [url=http://www.mquin.com/giuseppezanotti.php]giuseppe zanotti sneakers[/url] in the motion detector. The first is called passive infrared, which is another way of saying it will recognize body heat. The second technology is a Doppler shift which means that the detector detects movement in the area it is protecting.
Glass Break Detectors
Another well utilized device is the glass break detector. It is also wired much the same fashion as the powered motion sensor. This device is [url=http://www.1855sacramento.com/woolrich.php]woolrich parka[/url] mounted near solid glass windows and doors and will go into the alarm mode when it detects glass breaking.
Photoelectric Beams
Even though these powered devices can be utilized in a multitude of ways they are not used as much as I suggest for two reasons. The first reason is that they are a little bit more costly than other typically used devices. The more likely reason they are not utilized more often is that many alarm installers don't know how to install them. They need to be installed on solid mounting surfaces so that there is no blowing in the wind and they have to be calibrated both visually and electronically.
Get A Handle Of Your Cost
The keys to this [url=http://www.sandvikfw.net/shopuk.php]hollister outlet sale[/url] technology are capability and cost. The [url=http://www.1855sacramento.com/moncler.php]moncler outlet[/url] absolute best way to control these issues is to install the security system yourself. To install one of these systems you will [url=http://www.vivid-host.com/barbour.htm]barbour uk outlet[/url] need to buy an installation guide on installing a specific system. Believe it or not, it's not all that hard to install the system. You simply need to know exactly what equipment to purchase, what connectors to install, how to mount the equipment, and how to power it up and program the system. If you did not understand the significance of what I stated earlier, now is the time to grasp the message. Once the security devices and the security controllers are installed, the software does the configuration setup for you. That is what I am trying to say. Even though this is innovative technology, it is really simple to install.
Installing Numerous Systems
It has been my experience that when people are considering one technology for their new or remodeled home, they are probably considering other systems as well. It would be in your best interest to have installation manuals on each system you would like to include in your home. Read them all then buy your electronics, special tools, and cabling so that they are all on the job site in advance of your scheduled start date.
Unfortunately I am restricted in this article from expounding further about a alarm system. However, today I was able to at least acquaint you with the components of a security system and lay the ground work for a more in depth educational article about the many ways a security system can be wired to take advantage of the available technologies and therefore render a customized system for each home owner.
