How Burglar Alarm Systems Work

Burglar alarm systems provide peace of mind and security to families that have them installed in their homes. If you are looking to secure your home with an alarm system, knowing how one operates should be important to you.

Let’s take a closer look at alarm components and see just how burglar alarm systems work.

Main Control Panel – The main alarm control panel is the brains of any alarm system. Without it, there is no alarm system. An alarm panel should always be housed in a locked metal control box and mounted in an inconspicuous place.

Alarm Keypad – Keypads are important components to have on burglar alarm systems. Nowadays, keypads come with many different features and options. An alarm keypad is a console that can be used to arm and disarm the alarm system, bypass open zones, troubleshoot alarm issues, and more.

Alarm Power Supply – Burglar alarm systems need power to operate, regardless if they are hardwired or wireless. An alarm power supply, also known as an alarm transformer, plugs into an electrical outlet in the home and gives an alarm system the power it needs to operate efficiently.

Back-up Battery – All burglar alarm systems should have a back-up battery installed in them. If a home ever loses power, for any reason, the back-up battery will kick in and will power the alarm until the electricity is restored. Depending on the size and the condition of the system battery, this back-up protection can last a couple of hours up to a few days.

Motion Detectors – There are several types of motion detectors available to choose from for both hardwired and wireless burglar alarm systems. Some are very economical and straightforward, while others are a bit more expensive and complicated. Essentially, motion detectors work to detect movement in areas where they are installed.

Door and Window Sensors – Homeowners looking to add coverage to their doors and windows should consider adding door and window sensors to their burglar alarm systems. If a protected door or window is opened when an alarm system is armed, it will cause the alarm to trip. Depending on how the sensors are programmed, a door or window that is opened while the alarm is disarmed may chime locally in the home.

Glass Break Detectors – Glass break sensors, also referred to as audio detectors, are excellent devices to have on any burglar alarm systems. A burglar can get into a home undetected through a contacted window, if he shatters the glass and never opens the window to break contact. A glass break sensor, however, would detect the sound of the breaking glass and trigger an immediate alarm.

Shock Sensors – Similar to glass break detectors, shock sensors are installed on burglar alarms to detect the breaking of glass. Shock sensors, on the other hand, work a little differently. Rather than detecting the sound of glass, they work off vibration. This technology is similar to how a car alarm would operate.

Alarm Key fobs – Alarm key fobs are not essential to the operation of burglar alarm systems, but they offer convenience for those who use them. An alarm key fob looks similar to a car remote. Various key fob models offer different features and options; however, their main purpose is convenience. An alarm key fob allows you to arm and disarm your alarm system from outside of your home without effort. Some key fobs even have panic buttons enabled on them for extra security.

Alarm Sirens and Speakers – Sirens and speakers make noise when a protected zone is breached. Having local sound, regardless if an alarm is monitored or not, is always a good idea. Sound scares off burglars and helps police locate a home. Any homes with unmonitored burglar alarm systems are highly encouraged to install a siren or speaker for use as a deterrent and for added protection.
