Sound Generator for Alarm

This is sound generator circuit.You can use this circuit for your alarm circuits.Here I have used common IC 4011.This circuit gives about 10W through a 8 ohm speaker.This circuit can be control (on and off) with sw1.






Note

# Use 12V smooth power supply for this

# Build this on a PCB

#If you are unable to find IC 4011 you can use Ic MC14011 or TC14011
