How Do Security Alarms Work? A Jacksonville Tech Explains.

February 04, 2019

All security alarms are not created equal. This article will focus on a simple, monitored burglar alarm for your home. As you will see, such security alarms are just electronic devices. And, like all electronics devices, they can fail, so knowing how they work may give you a heads-up on troubleshooting and finding a local fix.

Start at the very beginning

Security alarms protect against burglary, fire, panic, and more. When something activates the alarm, it engages and sends a message to a central monitoring location. The electronically coded message conveys the confidential customer information to the central monitoring station that could help the customer in distress. The central monitoring station sends out the emergency services immediately, and they resolve the crisis.

Key components

Security alarms are not exactly a do-it-yourself project, but the core system is easy to understand.

  • Control Panel: Every system has a central processing unit, usually installed out of the way in a closet. This center control will receive and interpret signals from active and passive sensors and forward it to the monitoring center.  Newer systems are incorporating the keypad into the control panel and this one unit is displayed wirelessly on the first level of a home.
  • Keypad: The keypad is your access to the system. When the system is installed, you set up a confidential code that lets you arm or disarm the system. You would locate this near your front and rear entrances so you can deactivate the system when you enter. Most keypads also include a panic button that alerts the monitoring center even if there are no signals from the sensors.
  • Sensors: Most basic systems work with sensors attached at each door and window to detect unwanted violation of the perimeter.  Many systems also include a motion detector or a glass break detector.  You can upgrade the system with fire, acoustic, and infrared sensors.

You also may want to boost your home security system by adding carbon monoxide detectors, individual medical alerts, video cameras,and remote or mobile controls.

Protecting your system - protecting your home

Home (or business) security alarm systems are easily understood but not easily mastered. Once you have put time and money into selecting and installing your system, you need to accept that it will need repair, adjustment, and auditing from time to time. And, given the size of your investment, you want the kind of security service you can rely on.

That means you want a security service company that is local. A local service provider will respond quickly with solutions not suggestions. Performance by background checked and drug tested professionals will offer the kind of warranty and confidence you need. Dealing with people you know assures you the chance to hold them accountable for your security as well as your family's. Providers - who live and work in your community, contribute to the community's interests, and belong to the local Chamber of Commerce - bring a commitment to serve your needs and build a relationship for as long as your home security system lasts.
