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.
Burglar Alarm System
Burglars, it is the term used for persons who have an intention of breaking and entering another persons house. It is a crime interrelated to theft. If you do not want your house or your business to be burglarized, it is essential that you install a burglar alarm system in your home or business.
Statistics shows that individuals who have no burglar alarm system installed in their home or business tend to be burglarized more than those who have burglar alarm system. On the other hand, there are those who have burglar alarm system install on their properties but still get burglarized because either their system is not very reliable and effective or they forgot to turn on their burglar alarm system.
The first good step in protecting your home is by installing a reliable and effective burglar alarm system. There are lots of simple and inexpensive yet very reliable alarm systems out on the market. But having a more sophisticated burglar alarm system is also a good idea.
For better security against burglars, install burglar alarm systems on all of the entry points of your home or business, such as motion sensors, sensors that monitor or detect glass breakage, and for maximum protection, also include smoke and carbon dioxide sensors.
There are two basic types of burglar alarm system. One is a burglar alarm system that sets out loud alarms (usually sirens) and flashing lights on the house of establishment the alarm system is protecting. The other type of burglar alarm system has the same features as the first mentioned, however, it is connected or monitored by a security company twenty-four hours a day. With this kind of alarm system, when the alarm is triggered, an employee (usually these alarm systems are monitory by a computer) of the security company then calls the local law enforcement agency.
The most sophisticated burglar alarm systems have surveillance cameras or close circuit cameras strategically placed on your property or business establishment. Some of the detectors of burglar alarm systems are not only found on windows and doors, they are also found underneath rugs (motion sensors) and all of the rooms inside the house. Some highly sophisticated alarm systems even use laser sensors and heat sensor to detect any unaccounted for movements or change of temperatures.
Studies also show that having a god is one of the most effective measures in preventing burglars. Locks and deadbolts in some rooms are very much recommended to protect you and your love ones at home. Having a security alarm system in your home and business provides peace of mind to most homeowners but always remember to use it consistently or regularly. If you have a security alarm system in your house or establishment dont forget to arm them.
