Burglar Alarms: How Does it Work?

In today’s modern society, a burglar alarm is essential to keeping your property protected from criminals. These devices warn you of intruders and discourage them from further entering your premises. It’s no surprise that most businesses have burglar alarms installed to safeguard their assets and prevent unwanted losses. Swift action is important in the event of a break-in, which is where burglar alarms come into play. They facilitate a quick response by notifying people within the vicinity that a home security has been compromised.

It is therefore crucial to know the basics of a burglar alarm system and understand its uses.  How do these devices work? What makes them a staple piece of equipment for the average Australian? Today we’ll be discussing how a burglar alarm functions and how it can offer the level of protection your establishment needs.

What is a burglar alarm system?

Burglar alarms consist of electrical components that are installed in key areas of your home. They detect movement via motion sensors and contacts to identify if someone has intruded your property. For example, a window sensor uses a reed switch and magnet, with the former being attached to the window frame and the latter attached to the window itself.

When the window is opened, the magnet is pulled away from the reed switch, breaking the circuit and causing the alarm to sound off. The same thing applies to door sensors. The reed switch is installed on the top part of the door frame and the magnet attaches to the top part of the door. They essentially function the same way, with some sensors offering a bit more features like remote notifications and keycodes to deter even the most savvy of burglars.

Motion sensors work differently. Active motion sensors for example, put out signals that are disrupted by movement (i.e. when someone crosses the signal path), causing the alarm to sound off. Passive sensors on the other hand, use passive infrared sensors (PIR) that detect body heat and notice sudden temperature changes. These devices are sensitive to infrared radiation and are commonly used for home security purposes.

Components of a burglar alarm system

All of the aforementioned devices like window sensors, door sensors, and motion sensors are what comprise a burglar alarm system. These devices are all linked to a control panel that users can both activate and deactivate using a special input code, fob, or by operating the panel itself. Thanks to modern technology, burglar alarm systems can be integrated with your smartphone by downloading the app of your chosen security systems provider.

You can use your smartphone to activate sensors, remotely set and unset alarms, and even trigger an alarm in case of an emergency. The whole system is connected to an external siren installed on the outside of your property where it emits a loud, prolonged sound to alert those nearby of a forced entry. An internal sounder or bell is also installed to alert occupants inside the property that an intruder has broken in.

Most burglar alarm systems today are hooked to an ARC (alarm monitoring centre). This adds another safety feature wherein the alarm signals are sent directly to the ARC facility of your chosen security systems provider where they interpret the signals and make direct contact with you. If they haven’t obtained a response, they will contact the local police authorities to respond to your property.

What are the benefits of burglar alarms?

Sure, burglar alarms can protect your home and possessions, but what else do these devices have to offer? Are there other benefits to installing a burglar alarm to your establishment? Here are a couple of advantages that you can enjoy when you choose to install a burglar alarm system.

1. It gives you peace of mind.

Burglar alarms can provide you with a sense of comfort knowing that your property is protected from a break-in. You can peacefully enjoy your vacation without having to worry about your home being broken into by a burglar. By remotely controlling your alarm system, you can monitor the condition of your property anytime whether you’re at the office or at a holiday.

2. It reduces your home insurance.

Most insurance agents will advise you to install a security system of some sort into your property because it helps reduce insurance premiums. Your home is arguably one of your biggest investments and it only makes sense to keep it adequately protected from any damage. If your insurance company knows that you have a burglar alarm system installed, there’s a good chance they’ll reduce your home insurance because the risk of loss has been reduced as well.

3. Potentially deters crime

While burglar alarms systems might not fully dispel the possibility of a break-in, it does help reduce it somewhat by deterring burglars and other criminals. Say they do break in to your home and a large alarm sounds off, they’d be foolish enough to stay longer inside your property and will most likely scurry away to avoid being spotted. Having a burglar alarm not only makes your home, but also helps make your neighbourhood a safer place for everyone.

Understanding how burglar alarms work can go a long way towards keeping your household safe and protected from break-ins. These devices provide security and peace of mind for thousands of Australian households and is a worthy investment for those looking to have a security system installed.
