The popularity of the home burglar alarm continues to grow in the US with more and more Americans installing burglar alarms to ensure the safety and security of their family and property.
Several Americans go for the simple do-it-yourself system, which can be hard-wired or wireless. In this system, the alarm goes off when an intruder breaks the electrical circuit. This triggers a siren whose noise is loud enough to wake up the entire neighborhood.
The buyer has the choice to go for an alarm system that uses an open circuit or a closed circuit. In an open circuit system, the circuit is completed when a door or window is opened, and the alarm is triggered. In a closed circuit system the opposite happens. When a door or window is opened, the circuit s connection is broken and the alarm goes off.
