Hii friend,

Today I am going to make a circuit for Wire Tripper security alarm using 12V Relay.if someone cut the wire then buzzer will give sound and LED will be glowing.

Let's get started,

Step 1: Materials Required -

Components required -

(1.) Relay -12V x1

(2.) Buzzer x1

(3.) Connecting wires x1

(4.) Battery - 9V x1

(5.) Battery clipper x1

(6.) Resistor - 220 ohm x1

(7.) LED - 3V x1

Step 2: Connect Pins of Relay

Firstly we have to Connect common pin and coil-2 pin of the Relay as solder in the picture.

Step 3: Connect Buzzer to the Relay

Next solder +ve pin of buzzer to Normally Close (NO) pin of the relay as you can see in the picture.

Step 4: Connect 220 Ohm Resistor

Next solder 220 ohm resistor to +ve leg of LED as solder in the picture.

Step 5: Connect LED to the Circuit

Next Solder +ve leg of LED to +ve pin of buzzer and

Solder -ve leg of LED to -ve pin of buzzer as you can see in the picture.

Step 6: Connect Battery Clipper Wire

Next we have to connect battery clipper wire to the circuit.

Solder +ve wire of battery clipper to coil-2/common pin of the Relay and

Solder -ve wire of battery clipper to -ve pin of buzzer as you can see in the picture.

Step 7: Connect Wire Between Buzzer -ve Pin to Coil-1 Pin of Relay

Next solder a wire from -ve pin of buzzer to coil-1 pin of the Relay as you can see in the picture.

Step 8: Connect Battery and Cut the Wire

Now wire tripper security alarm circuit project is completed so connect battery to the Battery clipper and cut the wire which is connected between -ve pin of buzzer to coil-1 pin of the Relay.

Step 9: Result

As we will cut the wire then LED will glowing and buzzer will give sound.

This type we can make circuit of wire tripper security alarm using Relay.

Thank you
