At our store, we receive many inquiries asking if it is possible to reduce the volume of the siren, and since this cannot be done with the product alone, it is not possible to do so without replacing the siren with a lock-on, etc. However, we can reduce the siren volume at a low price by using the siren that comes with the product. I made an original so that the volume can be changed. I have uploaded a video that shows the difference in volume, so please watch it.
