Educate yourself about door alarms

Door Alarms and emergency exit alarms are one of the easiest ways to secure an area, and are one of the most affordable options. Although burglars may choose to break in using the window, main entries are still the most common entrance for theft. Securing your doors is the first step toward protecting your entire property.


Door Alarms work on one of two types of systems: a closed circuit or an open circuit system. Effectively, in a closed circuit system, the closed door completes the circuit allowing electricity to flow through it. When the circuit is broken, an alarm is triggered. Conversely, in an open circuit system, when the door is opened, the open circuit closes also triggering an alarm. This same idea is also used in window alarms.
