Alarm Systems

All kinds of alarms are currently one of the most effective methods of protecting property against burglary. Thanks to them, from year to year there are less and less intrusions into properties and thefts of equipment located, for example, in single-family houses. According to various statistics, the number of such cases decreases on average by 3 to even 5 percent over twelve months. This is also largely due to the improvement of alarm devices, which thanks to this work more efficiently and effectively protect residential buildings against intruders.

The history of using alarms in homes dates back to the 19th century. The first installation of this kind was patented in 1853 by a craftsman from Sommerville near Boston - Augustus Russell Pope. It was a groundbreaking invention at that time, because until that moment only domestic animals informed about the possible appearance of a thief. Compared to today's alarm systems, Pope's installation was very primitive. Today, alarms offer a variety of features to maximize the security of your property.

Alarms for home use

Home alarms, regardless of the type, work based on a similar scheme. Their main task is to alert the household members of the impending danger. Individual models do this by activating optical or sound indicators. These respond to specific signals that reach them from various types of receptors. Most often, you can find alarms equipped with infrared sensors that react to movement (PIR) or magnetic sensors (so-called reed switches), which are placed in windows, doors, entrance gates, garage doors, etc. The first of them activate the signaling devices when within them (when the system is armed), the presence of an unwanted person will be registered. On the other hand, magnetic sensors react when tampering with possible entrances to the facility is detected.

Alarm systems are quite easy to use. Configuring the installation, as well as arming or disarming it, consists in using, for example, a touch panel, tablet or smartphone application (applies mainly to intelligent buildings). Typically, this is limited to providing a special cipher.

What's important – alarm systems not only protect houses, but also public utility facilities, factories, production halls, workshops, etc. Their application is very wide and universal.

An alarm system consists not only of sirens and receptors. The heart of the installation is the control panel, which controls the mechanism and is responsible for its power supply. More advanced models also have a telephone dialer, GSM module or radio notification. These solutions provide information about the system to the appropriate people in a specific way. There are also installations available on the market which, after detecting undesirable actions, activate special locks preventing the intruder from getting into the building, as well as possible escape.

In addition to infrared and magnetic sensors, ultrasonic detectors are becoming more and more common. They use acoustic waves in a range inaudible to humans and are triggered by air movement. For this reason, they are quite often prone to false positives.

Speaking of modern alarm systems, it must be remembered that they are not limited to devices protecting property against theft. They also include elements designed to protect household members against other threats. Here it is worth mentioning, for example, fire alarms, which are triggered by smoke or thermal sensors. In offices or factories, special showers are additionally activated to extinguish the fire as quickly as possible. In addition, it is increasingly recommended to install carbon monoxide detectors. They should be installed wherever there is a real risk of gas leakage. If you use LPG installations at home, it is worth considering the purchase of sensors that react to this chemical compound.

Alarms and monitoring

An element that supports alarm systems is, of course, monitoring. This is an increasingly used solution, which can also be seen in private single-family houses. A very interesting technology that works well, for example, when going on vacation, is the simulation of the presence of a member of the household. Modern systems are equipped with this option and effectively deter robbers from breaking into our house.

In addition, wired and wireless alarm installations are distinguished. The latter were considered slightly less effective until recently, although technological progress has made their usefulness now the same as in the case of systems based on cables and wires. It is worth mentioning that while the use of alarms is not a difficult task, the installation of the solution requires appropriate knowledge and experience. Therefore, it is best to outsource it to a qualified company.

How to choose the right alarm

There are several factors to consider when deciding to purchase an alarm system. First of all – the size of the facility in which the installation is to operate is very important. The bigger the building, the more sensors are installed around it. It is also necessary to pay attention to the type of building and its function. In places where there is a clear risk of e.g. fire or asphyxiation, it is necessary to install the appropriate type of sensors. It is often recommended to also consider the terrain around the facility. If the alarm is to respond not only under the building itself, but also. after invading the property, it is worth opting for models with sufficient range. In addition, it is important that sensors installed outdoors have appropriate degrees of protection that prove the resistance of the equipment, e.g. to frost or heavy precipitation.
