Audio CD4001 based on Car Alarm Circuit


Posted on Feb 6, 2014

This is a simple alarm circuit for a checkup with a 4001. It can be used to protect our home, motorcycle, car or any other application that comes to mind. In this circuit will be a computer simulation with Livewire and then design the printed circuit Kicad. SW1 is a normally closed switch when pressed triggers the flip-flop formed by the two NOR g

ates of the CD4001 and remains there for a time determined by the time constant of R5-C2. This time it is keeping the relay RL1 and operated by its two contacts that investors control of two loads, for example, a siren and a light or any other that we connect to P3 and P4. We can replace the switch SW1 PIR motion sensor, an infrared barrier, a smoke detector, gas detector, a magnetic sensor, a panic button or other device to act as a closed switch and opened fire alarm.
