subject: How Do These Security Alarms Work? [print this page] Security alarms are really great for protecting your home and your family. It is a device that allows people to leave their homes unattended without having to worry. It also makes people feel that their homes are their strongholds.
Security alarms have sensors and bells that are installed in every part of the house, usually in entry points such as doors and windows. Most alarm systems, if not all, have magnetic sensors that keep the voltage flowing through the circuit while the entry points are shut. If these entry points are opened, the flow of voltage through the circuit is also cut. This causes the alarms to go off and the system to notify the monitoring agency of the unauthorized entry.
Also, these sensors have wires that connect them to the central monitoring system or a metal box. Inside the metal box, you can find batteries that are used in case there's no power or in case the power was cut by a burglar.
Security alarm systems also have keypads that allow you to activate or deactivate the alarms. Some security systems require the homeowner to input the password whenever they arrive home. They usually provide a certain amount of time for the owner to input the password before they sound the alarm and notify the monitoring company of any breach.
You can also find some security systems that have the ability to know which entry point has been breached and provide such information to the police. Some are even more advanced that they have their own security force which can investigate the unauthorized entry. Some have auto-dialers that can notify not only the police and monitoring agencies, but also the homeowner and other programmed set of numbers.
Some security systems can be used to monitor the arrival and departure of every individual that lives in your home via phone or pager. These types of systems are ideal for working parents who want to know the comings and goings of their children.
