Basically there are 4 components to an alarm system; the key pad, master control center and the various connected devices. I’m going to focus in on the key pad this talk.

The key pad got it’s name because the earlier alarm systems were turned on or off by a key. Now most systems are controlled by a “digital” key pad, but the name stuck, “keypad.”

Now that I’ve said that, there are different keypads that don’t even look like a keypad. Yes, they still have some systems controlled by a key, but most have buttons on them from 1 to 10. This is to let you “type in” your special code to tell the master control panel what you want the system to do. Some systems may have a “touch screen”. This looks like a computer monitor that has the various things on it that you want ths system to do. You touch the screen on the icon you want and it controls the system.

There may be several codes programmed into your system. Each person authorized to enter the building can be assigned there own code. The system will have a memory logging in the time and date the person either entered of left the building. You also may have a temporary code put in for a worker for the time he/she is needed to enter the building. This is taken out after the work is completed. Some people have their maid with her own code.

You also can program a special code for only certain times of the day. The master control panel will not let access on any other time periods.

A system also may have several “panels”. This I means you can have special codes for different areas of the building limiting a person only to the areas they are supposed to have access to. A good example of this is to have a jewelry draw, safe or file cabinet, silver closet with it’s own access code.

Key pads also have other information on them. They can tell you what doors or windows are not closed. What areas have been violated. The condition of the system. If there is something wrong with the system it will tell you the problem.

If you enter your home and go to turn your system off and it’s indicating you had an alarm while you wre gone, leave the home immediately. The person may still be in your home. Call the police. Let them search your home. Believe me, they would rather make this call than a homicide investigation call.

All this can be tied into an automated system that can be controll by a computer from anywhere in the world!!! Yes, you can even control your system anywhere. You can have a “spy in the sky” from anywhere if you have video included in the system. THINK ABOUT IT !!!!!!!
