Fire Alarm Systems
Many people are hurt, lost their possessions and die because of fire. Although fire can easily be prevented it is one of the leading causes of injury at home in the United States. In some cases where individuals die of fire, it is because they were not aware that their house or the building that they are on is on fire.
Fire alarm systems warn people of a potential fire. It warns the occupant while the still have time to either put out the fire or evacuate to safety. Most of todays fire alarm systems automatically call or notify the nearest fire department so that the fire will not spread out of control.
Fire alarms are either set off manually or by heat detectors or smoke detectors. Fire alarms are most of the time set to detect levels of heat or smoke which usually is an indication of fire. And some fire alarm systems have blinking or flashing lights for those who have hearing impairment. With todays technology, fire alarm systems can now be integrated with the home security alarm system for the utmost protection and safeguard of your home.
Smoke detectors is part of the fire alarm system, it detects smoke in the air and sets off an alarm thus alerting those nearby for a possible fire. Most smoke detectors detect smoke nowadays either by ionization or optical detection and some smoke detectors have carbon monoxide detectors that detect carbon monoxide by which also prevents carbon monoxide poisoning. The optical detector in smoke detectors is a light sensor which uses a beam like laser. These beam sensors then sends a laser like beam to other sensors, if smoke is non-existent, the laser like beam passes through the optical chamber of the light sensor in a straight line. If smoke is present, the laser like beam is scattered by the smoke particles as it enters the light sensor and the scattered light then triggers the alarm of the smoke alarm.
Ionization detectors are much cheaper than light detectors, although these types of smoke detectors are discouraged from being used because of environmental reasons. Ionization detectors work by detecting particles of smoke by a small amount of radioactive americium-241 (that is why it is discouraged from being used). This radiation of this material passes through an ionization chamber. This chamber permits the steady flow of current of electrodes, so that when smoke particles enter this chamber it interrupts the flow thus setting the alarm off.
Some fire alarm systems have sprinkler system that will contain or put off the fire before it becomes uncontrollable. However the only way to prevent fire is to take steps to be careful and take additional preventive measures.

Medical Alarm Systems
Emergency medical alarm systems are alarm systems used by patients who are recovering from surgery that can not move with ease, or individuals who are old, weak, in poor health, or individuals who have need of urgent medical attention to alert emergency medical personnel.
Most medical alarm systems use a wireless transmitter (usually a pendant) to trigger the medical alarm. When the medical alarm is set off, the transmitter then sends a signal to the alarm monitoring companys main control center or other medical emergency institution. Medical emergency personnel are then sent off to the location where the medical alarm system was triggered.
Emergency medical alarm systems have three essential components. These parts are: an emergency medical alarm button that is set in pendant of a bracelet or usually a necklace, an emergency medical alarm console to call for assistance, and an emergency medical alert service that monitors and acts in response to the request for assistance.
Emergency Medical Alarm Systems originated and were developed during the early seventies in Germany by Wilhelm Horman. Wilhelm Horman aim in developing broad organizations for ambulatory and non-ambulatory care for the old, ailing, those who live unaccompanied and disabled individuals. Wilhelm Hormans idea of medical alarm systems were seen as somewhat extensive which includes the transmission of the medical data and social communication. Emergency medical alarm systems are not limited for individual who are old. The technical execution was accomplished with the aid of AEG Telefunken Backnang GmbH. The emergency medical alarm systems were then introduced to the world in the early eighties.
Emergency medical alarm systems were then added with an assortment of accessories like smoke detectors, motion detectors and fall sensors. A flood of gadgets that can be linked over analog or digital ISDN connections are very much available these days.
In some circumstances like for example, if an individual that emergency medical alarm system falls or is all of a sudden develop bad health, that individual can trigger a call for assistance simply by pressing the button that is on the pendant or on the wrist (in case of a bracelet type medical alarm system) without the need of a telephone. The emergency medical alarm systems are programmed to configure calls or connections so that it will terminate any calls in progress and then initiate a call for emergency assistance. The alert is then sent to the monitoring companys main control center or the systems operator which is either a public emergency rescue service agency or a private security company. The medical data of that individual is then displayed so that the emergency response team will then know the address, medical condition and medical history of the individual.
For millions of people who are suffering from various illnesses, medical alarm systems are indeed a very important device in their everyday life.
The Alarm System
Summary: A brief timeline of Alarm Systems
The need to protect properties had surface even at prehistoric ages. Cave people make use of alarms such as traps and springs to protect their property. When animal husbandry was learned by man, dogs and mutts are tethered near the valuables to function both as alarm and guard.
In the middle ages, early alarms systems were in forms of large gongs which are struck in case of disaster and emergency. In the outposts, bonfires atop a structure (usually a watch tower) are used to warn settlements of impeding invasions.
The first true alarm system surfaced in 1852 and Edwin Holmes was the inventor. A simplistic device, it was actually a solenoid gong which sounded when the trip wire was disturbed. The alarm system was nothing compared to todays technology but in the industrial revolution era, where great inventions also surfaced like the electrical power generation and early forms of telephones, this invention was warmly received. And the inventions complimented each other too, especially for alarm systems and electrical transmissions which were shortly integrated into the device.
Alarms systems during this century make extensive use of DC alarm circuits and relays. These forms of alarm systems are wound along window sills and around door jambs coupled with conductive lead foil and magnetic or mechanical switches laced with thin resilient wire. Invisible trip wires and wooden dowel alarm screen are also state of the art.
It was another century later when alarm systems took a lengthier stride into advancement, with the advent of IC, circuit wafers, and nanotechnology. Smaller units integrated with microwave and ultrasonic motion sensors with entrance and exit delays are the modern forms of alarm systems. Perimeter sensors and live video feed was already a mainstay to most designs. Bell rings (on doors) are also a new innovation for alarm systems. All these technologies are still being used in abundance even to these days.
Alarms also made a sudden turn to other areas. Like the Bell ring, alarm systems are now used monitor volcanoes and earthquakes. Unconventional alarm systems such as the atmospheric alarm for space vehicles used to supervise the oxygen content and thermal heat regulator in foundries and mines.
Today, alarm systems have advanced even further. The rapid and expanded use of the network and web revolutionized the alarm systems definitely, as alarm systems have gone intelligent. Now, they sort problems themselves, minimize false alarms by identifying triggers, measuring size, weight and environmental factors. Some even detect internal circuitry problems, ensuring these alarm systems are functioning properly.
In an attempt to stay ahead of dangers, alarm system manufacturers have always integrated latest technology into the latest alarm system design. Guaranteed as technology moves still further, alarm systems will also keep pace with the latest tirelessly. Oftentimes, its just a matter of speculation how far will these systems.
Alarm Systems
Every time we hear the word alarm systems, we automatically think of business or home security. From the earliest alarm systems to the highly advanced, state of the art, sophisticated ones; alarm systems are the number one adversary of every robber and burglars in the whole word. Alarm systems are the first ones that every burglar must first neutralize or disable to carry out what they intended to do.
Installing alarm systems is another way of protecting the people and the possessions that you value at home and business. Alarm systems keep your possessions and property safe and also give you a peace of mind. The advantage of having an alarm system is that it serves a warning to any potential individual who have bad intentions be it on your home or on your business. If that individual notices that you have install alarm systems on your properties, they might get discourage from robbing or stealing.
There are lots of kinds of alarm systems. There are some alarm systems that are dedicated on preventing intrusions, while there are other systems that warn owners of fires. The complexity of these systems ranges from simple to highly advance, from dedicated systems to multi tasks systems, from silent to loud noisemakers. There are also alarm systems for vehicles like cars, trucks and boats.
An alarm system has five main components. The first component is the control pane. The control panel is the control system or the brains of the system. The second component is the keypad. The keypad is usually found in the vicinity of the main entrance. The keypad is responsible for the manipulation of the alarm system (allows you to disarm or arm your alarm system). The magnetic contacts is the third component of the alarm system. Magnetic contacts are installed on the windows and doors of your property. An alarm will sound if the if one or more of these contacts are severed if your alarm system is armed. The fourth component is the sensors. The most common sensor of alarm systems are motion sensors. Motion sensors detect any movement of the windows or doors or to where they are installed. Some sophisticated systems have heat sensors that detects body heat or change of temperature on a particular area. The last component of an alarm system is the alarms. Alarms are usually loud sirens. Some systems have flashing lights to attract more attention, while there are some systems that have silent alarms.
There are lots of simple alarm systems found on home improvement centers that are easy to install or more popularly known as do it yourself alarm systems. The best way of protecting the people you love and the things you value is to have an effective alarm system and use it regularly.
