What you need to know about Fire Alarm Systems
Summary: The cheapest is at $22, cheaper than your jeans. You wont be forgiven if fire breaks out because you forgo a $22 fire alarm system.
What is worse than burglary and theft in your property? The only candidate would be fire. If burglary happens on your property, at most all your valuables would be stolen. Cases of fire will not only decimate your valuables, your property will be razed. That is the most horrific nightmare of households.
True enough, property owners (households and offices) invests more in fire security and prevention than in thievery, even banks and holdings of valuables. Why, because fire is now also an element that burglars and thieves use as an accompaniment for their sting. Of course, burglary is still an important factor.
In effect, most total security units now include burglary and fire alarm system. Such systems supervise doors, windows and large spaces that would require such devices, e.g. theft prone areas (entry areas) and high fire risk areas like the library and the living room, especially above the carpets. Some total security units also include a 24 hour monitoring service that charges monthly dues.
Due to their relatively high cost, these total alarm systems are only found on homes that clearly could afford such. Smaller conventional households will make do of a smoke detector and a tank of fire extinguisher. But dont be hasty to discredit smoke detectors. Though very cheap, they are very, very reliable and often would warn the earliest signs of fire.
So why pass up the prospect of protecting your homes. For only $22 you can make one room fully prepared to meet fire accidents. (Actually, it only goes off, you still have to manually operate the fire extinguisher). Of course these type of fire alarm systems goes hand in hand with a fire extinguisher, which is yet another essential. Why, most fires can be extinguished with water (or cushion or mat, as long as it smothers the fire) but some fires DO get bigger with water, in fact grease fires are really dangerous if applied with water. Thus, fire extinguisher should it be.
There are two types of smoke fire alarm systems, and each one has a design specific to the area. Ionization detectors are the cheapest (the one Ive mentioned) and the easiest to install, the easiest to maintain but is more likely to generate false alarms due to their sensitive nature. Ideally, ionization detectors are to be installed on rooms having volatile materials and photoelectric for rooms having heavy furniture that smolders before bursting into flames.
While most fire alarm systems is use today are smoke detectors, other models make use of heat and temperature to detect the presence of fire. In some cases like gasoline and alcohol burning, these fires produce little smoke which may not trigger the smoke detectors immediately. Accordingly, these types are to be used.
Fire is one serious household accident that may or may not come during your lifetime. Just because there where no such incident before doesnt mean your home is immune. The cheapest is $22.96 at www3.shopping.com, way cheaper than your Nike. You wont be forgiven if fire breaks out because you forgo a $22 fire alarm system.
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.
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.
