Burglar Alarms Guide

By Christopher Williams

An American by the name of Edward Holmes patented the first electro-mechanical burglar alarm in 1852. It was very uncomplex in nature, but well-received by the general public. When a trip wire was tripped a gong was struck by a solenoid. The trip wire was usually wound around doors and windows. The family dog was typically the best form of alarm and protection prior to this invention. It wasn't until the 1900's that this alarm saw it's most prominent advancements.

There are three main components to the basic burglar alarm system: the detection device, the main control unit, and the siren or sounder. The detection device, depending on what it's set for, can monitor motion, heat, noise, shock, vibration, and smoke (if the unit is also used for smoke detection). When the device is triggered it sends the message to the main control unit, or the brain. The data is quickly analyzed and it is then determined whether or not to sound the alarm.

A wireless burglar system is relatively easy to install, and doesn't require a specialist. Every component of the wireless system contains a radio transmitter/receiver which allows the detection device to communicate with the control unit. With this setup there are no worries about running wire, the parts can be placed just about anywhere, and it is easy to add onto the system or move it around.

A monitored home security system allows the home to be protected 24 hours a day by an alarm company. When a detection device is triggered the alarm is set off and the information is sent to the alarm company monitoring the system. This gives the homeowner peace of mind when they are not at home. There is also minimal maintenance to the homeowner, as the agency hired to install and monitor your home will also ensure that the system is always operable.

Magnetic switches can be used on doors and windows as a burglar alarm. They are very easy to install and maintain. In the simplest terms, there is a magnet and a switch that are lined up on the door or window. When the connection is broken between the two, i.e. the door is opened, then the alarm goes off. The draw-back to this is when the window or door is then closed, the alarm will usually stop.

There are different reasons to have a burglar alarm, and they are no longer just for the wealthy and business owners. They are still used to protect valuables, but are also widely used to protect the family as well. Not all intruders are after monetary riches. The cost of home security systems has decreased, making them very affordable.

It is very important to choose the right burglar alarm. The money you have available to spend on an alarm, if you are able to install it yourself or need a professional to do the job, and why you need the alarm system are all key points to consider before you make a purchase. To ensure that you are completely satisfied with your choice, do some research and educate yourself on the alarms available.
