A Transistor Based Motorcycle Alarm circuit

This circuit includes a timed output and an automatic reset feature. It can be manually operated using a key switch or a concealed switch. By incorporating an external relay, the circuit will automatically engage or immobilize the machine each time the ignition is turned off. It is easily adaptable for a 6-volt system, making it suitable for protecting classic motorcycles.

The described circuit is designed to enhance the security and functionality of classic motorcycles by providing a timed output that can be used to control various electrical components. The automatic reset feature ensures that the circuit returns to its initial state after a set period, which can be beneficial in preventing unauthorized use of the vehicle.

The manual operation capability allows the user to activate or deactivate the circuit as needed through either a key switch or a hidden switch, adding an extra layer of security. The use of a hidden switch can deter potential thieves, as it is not easily detectable.

Incorporating an external relay into the circuit design allows for the automatic immobilization of the motorcycle when the ignition is turned off. This relay can be configured to interrupt the power supply to critical components, such as the ignition system or fuel pump, effectively preventing the motorcycle from being started without the proper authorization.

The circuit's adaptability for a 6-volt system is particularly advantageous for classic bikes, as many older models utilize this voltage standard. This feature ensures compatibility with existing electrical systems, allowing for straightforward integration without the need for extensive modifications.

Overall, this circuit design provides a practical solution for enhancing the security of classic motorcycles while maintaining ease of use and adaptability to existing systems.This circuit features a timed output and automatic reset. It can be operated manually using a key-switch or a hidden switch. By adding an external relay, it will set itself automatically - and/or immobilize the machine - every time you turn-off the ignition. It`s easily adapted for a 6-volt system - so it will protect your "Classic Bike".. 🔗 External reference
