Things to Prepare
Before we move on how to make a door alarm with a buzzer, here are the things you will need to prepare.
- mini buzzer
- Electrical tape
- Insulated/flexi wires
- Wall hangers
- Wire snips
- Wire strippers/knife
Steps on How to Make a Door Alarm with a Buzzer
Step 1: Prepare the Wires
Strip off a ½-inch of insulation on both ends of the flexi-wire using a knife. The insulation should carry two wires. Take the wires and connect them to the metal connectors on a 9-volt battery holder. Tighten them using the electrical tape. Join the additional wire to the electrical buzzer. Both wires must be joined to the electrical buzzer joints and held safely with electrical tape.
Check if it works properly by joining the battery to the holder. You should hear the buzzer go off if proper connections are made. Otherwise, reposition the wires. Once you hear the buzzer, remove the batteries.
Step 2: Assemble the Wires
Go down the flexi-wire to around half a meter, and cut one of the wires in half. Divide both wires that are inside it, and cut one of the wires. Peel both the cut wires using the knife, and try not to knick the other cut of the wire. Strip about a centimeter each. Set aside.
Open the clothespin, and stick two thumbtacks inside the opening of the two. The thumbtack heads should come in contact with each other. Don’t push them all the way down yet. This is to guarantee that the buzzer will sound once it is finished. Take the two stripped wires, use one side of the wire, and put it underneath the thumbtack head. Push the thumbtack down tightly, so the wire is secured as well.
Step 3: Assembly the Alarm
Connect the other wire to the opposing end of the clothespin, against the other thumbtack. Be sure to press tightly to secure the wire and the thumbtack into the clothespin. Close the clothespin, and connect the batteries back to its holder. If everything is placed correctly, the buzzer should sound.
If there’s no buzzer, reset the wires. Open the clothespin and set it on the doorframe. When the door closes, the two thumbtacks should not touch each other, and when the door opens, the thumbtacks should come in contact.
Connect the rest of the assembly to the back door. Re-check the alarm to guarantee that it is working correctly. Fasten the assembly to the back of the door with tape or string to secure that it won’t move anywhere. Now, you just have learned how to make a door alarm with a buzzer.
Learning how to make a door alarm with a buzzer is easy and doable. The wires, buzzers, and batteries must be appropriately attached and fastened. A DIY door alarm may not be as refined as commercially-made ones, but it is more affordable, and it might just be the thing you wanted for your home protection.
