To make an earthquake alarm model, you can use a sensitive seismic sensor connected to a microcontroller or Raspberry Pi board. The sensor should be programmed to detect vibrations characteristic of earthquakes and trigger an alarm system such as a buzzer or LED lights. You can also add a battery backup system for continuous operation during power outages.
The switches to activate the backup alarm are usually placed within the transmission. If you don't feel like going through this hassle, you can connect the positive wire for the backup alarm to the circuit which activates the backup lights, or you can put a manual switch in the cab to work the backup alarm.

To help you turn your backup sensor on I would need more information. What does the backup sensor go on? What type of vehicle? What year is it? an what model vehicle is it?
Because you haven't diagnosed it to determine what repair needs to be made. Either it's not getting power, it's not grounded, or the backup alarm itself is toast.
If your smoke alarm is still chirping after you changed the battery, it could be due to a few reasons such as a faulty battery, improper installation, or a dirty sensor. It is recommended to check the battery connection, clean the sensor, and ensure the alarm is properly installed to troubleshoot the issue. If the problem persists, it may be best to replace the smoke alarm.
