It is practical nowadays to have your own house alarm in order to protect your personal belongings from pesky intruders. Having to buy prepared security systems proves to be very costly and sometimes impractical. Others employ expensive security cameras and hire security staff, but still nothing beats the old fashioned style of protection—burglar alarms. Here are some easy steps in preparing your very own house alarm.
- Purchase all needed materials and equipment. In setting up your own house alarm, you need to get all the materials required in doing the said task, which would include practical ones like electrical tape, soldering equipment, scissors and sticky glue among others. Go for stores where you could buy these cheaply and at the same time, not sacrificing quality.
- Acquire a good buzzer and the appropriate power supply. A power supply is said to be a device, which supplies electrical energy to one or more loads. Its mechanism involves changing one type of electrical energy to another. Obtain a power supply that would have, as much as possible, the same or less voltage as the requirements of the buzzer, and equal or a little bit more amperage. Locate shops which sell their electronic equipment for cheaper prices. Test your equipment first before leaving the shop and always keep your receipts for possible reimbursements if something unexpected happens.
- Construct the alarm. Set up a connection between the power supply and the buzzer by soldering it directly to each other. You may also use a wire to bridge them together. Using a scrap piece of board or plywood, attach both your buzzer and power supply. Wrap both of them using electrical wire to prevent swiveling and other unnecessary movement.
- Create a switch for the alarm. Prepare two long wires, covering the distance from the power supply to the door with a little allowance. Create a switch mechanism using a magnet and an iron plate. Stick these two equipments together and then attach the corresponding wires. The alarm works when the magnet attaches on the iron plate from the action of opening the door. Connect the other ends of the wires to complete the circuit. Again solder each free terminal of both power supply and buzzer. Be cautious of accidents and always check if the power supply is turned off when completing the circuit.
- Check if the alarm works. Let the magnet come in contact with the iron plate before turning on the circuit. This would make the buzzer go off. After unplugging the circuit again, attach the iron plate to near door using electrical tape. Leave the magnet right in front of the door in such a way that when the door opens, the magnet latches on the plate thereby turning on your alarm. Finally, plug your circuit again and try out your house alarm.
Now that you have built your very own house alarm, no burglar or stupid crook would dare break in your house and steal your belongings. Just don’t forget to test your alarm once in a while to make sure that it’s still working.
