cmos based vehicle anti theft alarm
The car alarm circuit is designed to enhance vehicle security by providing a range of features that deter unauthorized access. The Exit and Entry delays are crucial for allowing the user time to enter or exit the vehicle without triggering the alarm. Typically, these delays are adjustable, allowing the user to set the duration based on personal preferences.
The instant alarm zone is a critical feature that activates the alarm immediately upon unauthorized entry into specific areas of the vehicle, ensuring rapid response to potential threats. The intermittent siren output serves to draw attention to the alarm condition without causing continuous disturbance, which can be beneficial in residential areas.
The automatic reset function ensures that the alarm system resets itself after a designated period, preventing unnecessary battery drain and allowing the user to regain control of the system without manual intervention. This feature can be particularly useful in scenarios where the alarm is triggered accidentally.
Additionally, the integration of external relays provides flexibility in enhancing the alarm system's capabilities. By utilizing these relays, users can immobilize the vehicle's ignition system or fuel pump, rendering the vehicle inoperable to unauthorized users. Furthermore, the ability to flash the lights serves as a visual deterrent and alerts nearby individuals to the alarm condition.
Overall, this car alarm circuit is designed to provide comprehensive security solutions tailored to meet the needs of vehicle owners, combining functionality with ease of use to ensure maximum protection against theft and unauthorized access.This car alarm circuit features Exit and Entry delays, an instant alarm zone, an intermittent siren output and automatic Reset. By adding external relays you can immobilize the vehicle and flash the lights.. 🔗 External reference
