Burglar Alarm Installation Procedures and Tips

The complexity of an alarm system depends on the establishment it is going to be used. The more entry points, the more complicated the electrical circuit for the alarm system. Most of the time, complex alarm systems are installed in business establishments like stores. The need for a complex alarm system for this kind of establishment is higher than any building.

Most homes use simpler versions of alarm systems. In many cases, smaller homes use simple unmonitored alarm. Using alarm systems in homes is grounded in the concept that even homes and the persons residing in it needs protection too.

Alarm systems vary according to the task it is going to do. For example, when a person wanted to detect smoke or fire, he may choose installing fire alarm system in his house. Every type of alarm system works specifically to a certain job. The most common used alarm system type is the burglar alarm system.

Burglar alarm systems vary too according to the size of the building. Also, the installation complexity of such may change depending on the number of entry points to be integrated. In addition, burglar alarms may also be monitored by the police or relayed to a telephone line.

Most burglar alarm systems are installed by professionals. In many cases, the company where one bought the alarm systems is the one responsible for the installation of the alarm system.

However, there are also alarm systems that can be installed by do-it-yourselfers. These alarm systems are being sold in kits. Every kit contains complete components that one needed for the installation.

Before installing an alarm systems take note of the following considerations for a proper installation:

• The number of entry points in the house. Knowing how many entry points you have in your home will determine how many sensors you need to install. Entry points are not limited to doors. It can also be windows, fire exits, etc.

• The type of alarm system you brought. Is it a burglar alarm or a combination of a burglar alarm and a fire alarm? The more sensor types the complex the circuit will be.

• Note of the strategic place where you are going to put the control panel.

In installing the burglar alarm system, the very first component to be mounted must be the sounder or other known as the buzzer or bell. Think of where you want it to put. Most of the time, sounders are located in places that can easily be seen to warn off any burglar intending to break into the house. When the sounder is installed outside, one must make sure that it is mounted away from extreme heat or moisture. It is also advisable to enclose the sounder in a box to protect it from any atmospheric condition. Make sure also, that the sounder is placed in a way that it can be heard loudly.

After installing the sounder, the next component that must be installed is the sensors or the switches. Carefully install the sensors in edges of the windows and doors. Make sure that the magnet and the sensor is not too far from each other so that the sensor will have enough magnet reception. Do not put it otherwise too close to each other or else the magnet may sag to the sensor which can damage any of the component part.

Mount the wires neatly and integrate the rest of the components to the control panel. Test the system if it works properly by closing and opening the entry points. Make adjustments when there are components that do not work properly.

* Solicit referrals from your neighbors, relatives, friends, and insurance agents.

* Call the companies suggested by your neighbors, relatives, and insurance agents, as well as those listed by the National Burglar and Fire Alarm Association. Make sure that they are duly licensed and recognized by the National Burglar and Fire Alarm Association. Moreover, inquire if they take part in the Installation Quality Certification Program.

* Reduce your selections to approximately five companies or less.

* Arrange for a meeting with the representative of the companies. Schedule the appointment in an occasion when all the members of the family can attend. This is to be sure that all of them will know what the representatives have to offer about their systems.

How the Alarm Monitoring System Works

Burglar alarms are in electronic form. A simple set-up of an alarm system includes a sensor that is connected to one or more control units. When the sensor is triggered, the control unit seeks for a way to announce the alarm.

Basically, alarm systems can either be hardwired or wireless. The wired systems are usually used with sensors, smoke detectors for example, which demand power for reliable operation. Wired types come with the advantage of detecting tampering. However, wired systems are expensive to install. On the other hand, wireless alarm systems are easier to set-up. Instead of wires, they utilize transmitters. Wireless systems require constant supervision and maintenance to ensure efficient operation. If for example, the sensors or batteries have not been constantly checked, the system may not perform at its peak.

Alarm monitoring is employed in systems with a remote alarm output. In such systems, the control panels are connected to predetermined monitors, and they are configured in various methods. One includes a direct connection of the system to a responder, or a central station, such as a police quarters. However, this kind of configuration is becoming less popular because it is expensive. Direct monitoring connections can usually be found only in Local Government institutions, State, or school campuses where there is a dedicated security.

More conventional alarm systems make use of Public Switched Telephone Network, or PSTN. This configuration features a digital phone dialer unit which will dial the central station, which in turn will announce the alarm. The monitoring system can identify the physical location of the sensor that has been triggered with the use of certain programmed encoders. Most alarm control panels are designed with backup dialer ability that can be used when the primary PSTN route is not functioning well. The secondary dialer can be connected to a separate phone line (or an encoded radio, mobile phone, or internet interface gadgets) to entirely evade the PSTN. This is because if the primary lines have been tampered, alarms could still be raised via the redundant dialers and early warnings of pending problems can be advised.

In situations where the building is remotely located, PSTN service may not be feasible and channeling a direct line may be too expensive, there is still a way so your security can be monitored. And that is by using wireless phones or radio networks as the principal communication line. The use of the Internet as a main communication method is still very controversial within the alarm monitoring business. This is because an alarm signaling method needs to observe urgency and immediacy, and the authorities are doubtful of the quality of service of public internet.

When monitored, the alarms and speaker phones permit the central station to communicate with the owner, or even with the intruder. For monitored burglaries, the speaker phones let the central stations to convince the prowler to back off and give up as police units have been sent off.

Considering some factors, such as the location of the zone triggered and time of the day, the alarm monitoring center may perform various actions automatically. Some instructions they may initiate include calling the police stations, fire department or ambulance. They may also choose to check if the alarm is true. Some systems come with video surveillance to capture the actual acts of intrusion or other emergency cases on tape.
