If you’re looking at home alarm systems, you should know that how they work is actually very simple and should be easy to understand, even for the least technologically savvy among you. They are made up of several components, each of which is essential to the functioning of the system as a whole. Here is a careful description of what makes up home alarm systems, which is critical to you understanding how the alarm will work for your home security system.
The Alarm Itself – The alarm itself is a device that produces a sound. This isn’t just any sound, but usually a ringing, and a quite loud ringing at that. Some are 80 decibels, others are 95 decibels, but no matter what, the sound is usually very loud and not the most pleasant. The reason it is so loud and annoying is so that it can be sure to wake you or the neighbors up if you are sleeping. The alarm may also have flashing lights that accompany the sound. Often, home alarm systems are connected to a monitoring service, so that when system goes off, a professional home security company receives the alert. When they receive calls from home alarm systems, these companies know to immediately phone you to see whether or not the alarm was falsely activated. If they cannot get a hold of you, they’ll immediately call the police to investigate the situation.
How to Control It – Controlling the alarm is quite simple. It’s hooked up to a control panel so that you can program when to turn it on or off. For example, you can tell it to turn on with a press of a button when you are leaving your house. You can also tell it to turn on at a certain time of night, or whenever you are going out of town. Home alarm systems are consumer friendly and easy to work with, so that you should not have much trouble setting them according to your needs. In addition, the control panel is the same place you go to in order to turn off the alarm when something falsely triggered it or when an intruder is caught. Simply go to the panel and enter your personalized authorization code to reset the system.
What Sets Off The Alarm – This is probably the most complicated part of understanding the alarm system, so we’ll try to state it as simply as possible with an analogy that will hopefully be easy to understand. There is a circuit between two points, like a rope between two trees. Electricity flows through this circuit when it is connected, or when the rope is tied to both trees. Then, a switch will either open or close that circuit, just like tying or untying the rope from one of the trees. An open-circuit system is usually unconnected, and when the switch is flipped, the circuit will then be connected. With our rope and tree analogy, this means that usually one end of the rope is not attached to one of the trees. The tree WITH the rope attached is the “alarm tree”. When the rope is tied back on the other tree (flipping the switch), the rope is now connected on both ends and the “alarm tree” will sound. On the other hand, a closed-circuit system is usually connected, and when the switch is flipped, the circuit will be broken. Again, with the tree analogy, this means that usually both ends of the rope are tied to the trees, and when one is untied (flipping the switch), the “alarm tree” will sound. So in home alarm systems, for example, a door will have an alarm circuit connected to it. With an open-circuit alarm system, when someone opens the door, the circuit closes or connects and the alarm will sound. With a closed-circuit alarm system, when someone opens the door, the circuit breaks and the alarm will sound. In either case, the change in the flow of electricity through the alarm circuit will activate the alarm.
That’s all there is to it. With these three major components, home alarm systems keep your homes secure from intruders who intend to break in and burglarize your homes. Thankfully, home security systems don’t need much more than that to keep you safe and secure.
