I want a circuit which will be powered by 12 volts battery to generate a sound through a siren horn for 5 seconds at frequency of 15/30 minutes. For example, from the moment I turn on the circuit, it should sound the horn for a duration of 5 seconds for every 15/30 minutes. We need to have a switch which will decide between OFF time period for 15 minutes or 30 minutes. Once the battery is discharged, we would be able to recharge the battery using 220/230 V AC supply. The circuit should also have an LED which will indicate that the battery is fully charged. The siren horn will generate sound when we provide input of 12 V DC. So the input to the horn should be a 12 V DC supply for a duration of 5 seconds and for the next 15/30 minutes, no supply should be provided. Refer the diagram & image of the siren horn for better understanding of the function.
