What Are Alarm Systems?

Car alarms fall into the two major areas, passive and active or a combination of both, depending on how the car alarm is activated and the way it works. Alarms that are passive immediately are armed when you turn off the car and close all the doors. You do not have to worry whether or not you put on the alarm. On the other hand, you have to manually arm an active alarm system. Alarms that work both in a passive and active mode are most helpful for people who often forget to set their alarm. There are also two different types of codes for car alarms that use a code system. It is best to buy a dynamic code, because it is more difficult to steal that a static code alarm, which can more readily be deciphered with a radio transmitter called a code grabber. Unfortunately, neither the passive/active or static/dynamic alarm systems entirely stop stealing, so you may also want to consider a vehicle with a built-in tracking system that continues to send out signals.

A wide variety of burglar alarm systems are made to protect houses, companies, cars and other personal property. Home burglar alarms work on sensors, normally connected to a central control via a hardwired or radio frequency, or wireless, signal. The alarms are put on locations, such as entrances like windows and doors. When a motion sensor is set off, the alarm immediately transmits a very loud sound and calls for emergency response. Some burglar alarm systems only go off when there is an intrusion. Others, which are for security and home safety, sound in case of fire and other emergencies, too.

Some alarms only sound at the scene of a crime or emergency, and others, so-named monitored systems, send a signal to the police and/or fire department as well. Sometimes monitored alarm systems are more expensive than other types, but they work better in the long run. Another feature on a sophisticated alarm system lets you send a secret code when you are forced to turn off the alarm. Instead of putting in your usual code number, you put in a duress signal that does not alert the robber that anything is amiss. Other settings on a monitored system include an alarm that alerts the police when there is a call for help, wakes you up in case of fire, or detects carbon monoxide fumes.

In these days of increased thefts and fires, most commercial buildings have some form of alarm system, even if a very simple one. The alarms can be used in case of intrusion, theft or fire, or unhealthy fumes, toxic gasses and smoke. Some of these buildings that most use alarms are banks, retail outlets, malls, schools, libraries, medical facilities and multi-family housing areas. Many of these alarm systems also include surveillance.

Remember these tips: Do not forget to turn on your alarm, because you are in a hurry or just too lazy to go a little further and turn it on. Always get your alarms checked when it is time for routine maintenance. Even when the alarm is maintained, conduct frequent tests, so people know how to respond when they hear the alarm. Keep up-to-date on your system and changes in the security industry, so you use the most advanced system needed. Do not skirt your responsibilities for paying the bill for your alarm system. It is better to be safe than sorry.
