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.

ADT Alarm System
The ADT alarm system is one of the leaders in providing electronic home security systems and services in the United States. The ADT alarm system features state of the art, highly advanced and sophisticated security systems and services.
The ADT alarm system is composed of security system, surveillance system or electronic article surveillance (close circuit system), fire detection system, alarm system, gaseous extinguishing systems.
The ADT alarm system is the oldest and one of the largest electronic home security companies in the United States. The American District Telegraphy Company which was founded way back in 1874 is the forerunner of the present ADT alarm systems and service. The American District Telegraphy Company originally offered simple call boxes or telegraphs. At present, the ADT has become the top electronic security company that provides security protection of the top companies, financial institutions and millions of homes in the United States.
The ADT alarm system has four levels of safety measures against burglars. The first level is the yard sign. The yard sign serves as a warning to potential burglars. Most burglars are discouraged from committing burglary whenever the house or establishment is advertised with the alarm system. The second level in the ADT alarm system is the window decals. Window decals serve as a secondary warning in case if the burglar has not noticed the yard sign. The third level of the ADT alarm system is the alarm siren. A very loud alarm siren will be triggered if unauthorized entry is detected by the ADT alarm system inside the house or establishment. The last level of the ADT alarm system is the round the clock monitoring. The ADT alarm system monitors the house or establishment twenty-four hours a day and will alert or call the local law enforcement agency if the alarm is triggered.
The ADT alarm system is monitored by highly certified staff. The ADT staffs are trained to manage emergencies such as flood, fire, and carbon monoxide poisoning. The ADT Home Security has an extensive array of equipments available, depending on the request of its clients.
The main product of ADT Home Security is alarm monitoring services. ADT Home Security maintains a centralized monitoring base that collects electronic signals from the ADT alarm systems installed in the United States. If the security system is triggered, such as an unauthorized entry or intrusion, the security system then sends off a signal to the ADT monitoring station. A monitoring specialist then checks the data that is sent by the security system and the specialist then chooses what type of response the alarm signal requires. In some cases, the monitoring specialist will contact the residence or the owner of the establishment by the use of a telephone to further investigate and determine if the alarm is false or not. If the specialist determines that the situation is not a false alarm, the local police department is then contacted.

Door Alarm System
Summary: The first ever alarm system was a straightforward device consisting only of a power, a solenoid gong to serve as the alarm and the trigger
The first ever alarm system was a burglar alarm. This door alarm system was a straightforward device; the circuit consists only of a power, a solenoid gong to serve as the alarm, the switch or the trigger. In an era where inventions and discoveries are taking place one after the other, the alarm system was surprisingly received warmly, even though major inventions such as the telephone did also take place.
Though Edwin Holmes door alarm system is somewhat primitive compared with todays technology, it is still surprisingly effective. The design flaws of the door alarm system make it a bit unreliable but if you are interested, read on as I detail how to put together your own door alarm system.
Note that this little DIY (do-it-yourself) exercise needs elementary electricity skill. You should know also the dangers of naked lines and electrical hazards. So without further ado
Choose a switch. The suitable one is a press switch. To help you illustrate, study the door switch of a refrigerator. When you open the door, the light goes on, right. The circuit we are going to make is exactly the same, except our resistor wont be a light bulb but instead a buzzer. So choose a press switch that completes the circuit when the button is released. If your not sure, ask the help of the proprietor of the hardware store.
Now choose a buzzer. The buzzer is purely your choice. It could be a standard BUZZ or a subtle Ding-Dong as long as it is loud enough to be heard for it to be useful.
Now, choose another switch. This switch is used in setting the device on. Because without it, your door will constantly alarm whenever somebody passes through the door.
Connect the circuit. Start first by choosing a spot for the buzzer. The best place for you to place the buzzer would be in the stairs area or the junction of two rooms (if its a one story house). Attach the trigger switch to the doorframe, basically just like the refrigerator device. In most cases you have to extract a piece of the wood to have a place for your switch. Close the circuit by attaching to a power supply. Remember to turn off the power before working. Attach first the wire to the alarm, then to the trigger switch then to the control on-off switch then lastly to the buzzer. Attach the circuit to the power lastly. Check the connection, if you have a tester its time to use it now. Check everything thoroughly before putting the power back on.
When activated the door alarm system will buzz every time the door is open. Now you see the flaw. It only takes the intruder to close the door for the alarm to silence. But still, in most cases. The alarm should jolt everyone to wakefulness.

The Fundamentals of a Burglar Alarm System
Summary: The most fundamental design of a burglar alarm system is just a simple electric circuit that sounds whenever a circuit is completed or broken. So fundamental that you can make one yourself.
Todays burglar alarm systems have gone a long way from being a simplistic device with a solenoid gong that Edwin Holmes has made in 1852. Todays burglar alarm system incorporates the internet and radio waves, making it really a difficult beat for burglars.
The most fundamental design of a burglar alarm system is just a simple electric circuit that sounds whenever a circuit is completed, or in some designs, broken. This action is called breaking the circuit, and other than your dog maybe the only alarm that guards your doors and windows. How do burglar alarm systems work?
In every electrical circuit, electricity flows on a completed path between two points of opposite charge, negative and positive or input and output. The circuit and the electricity is controlled by means of a switch, an on or off device where you can open or close, or reroute a part of the circuit.
So for example, in a standard circuit that consists of a power supply, a line, switch, bulb, and line back to power supply, every time the switch is turned on the bulb lights. Burglar alarm systems work that way: whenever the alarm is set on active, current passes through the doors and windows. Anyone attempting to open a door will educe the alarm.
One problem though with this design, to stop the alarm you only need to close back the door and the circuit in once again complete. Thats the function of the control box that accompanies most modern alarm system. This control box is connected to all system alarms. Once the alarm is triggered, this control box won’t cut it off until somebody manually cuts off the circuit. Subsequently, the control boxes are usually hidden and equipped with a lock so the burglar wont be able to find it.
Because this burglar alarm system is quite rudimentary, you can make one perfectly for your home. With proper knowledge of electricity you can homebrew the Break Circuit Burglar Alarm System (you may call it this way). For ideas relating to such circuits, study how refrigeration lighting comes to play.
Homebrew your Burglar Alarm System
Opening the refrigerator door emits a light. On some designs, the switch is embedded in such a way when you open the door the switch is released, completing the circuit and light goes on. Similarly, embed a press switch on a door frame. Work the circuit in such a way that the pressing will break the circuit and releasing will complete. Now attach the circuit to a buzzer.
Actually, you can imagine many uses with this circuit design. Why, try hooking it up on a disc player and invite your special someone over for dinner. Of course for the dramatic to take effect, you should let her open the door.
