Yes, it can be changed.

There are both ways to change the siren sound: changing the timbre and adjusting the volume.
Depending on the situation, it may be handled by replacing the siren unit itself, and depending on the product and configuration, it may also be possible to make adjustments via settings.

Also, some people would like to operate the system with the volume slightly reduced, depending on how the alarm is used and the parking environment. At LOGON, we don’t just aim for it to be loud; we guide you while considering the balance between how it’s used and the sense of reassurance.

However, how much it can be changed depends on the type of security system and siren that are installed.
In our shop, we provide guidance while checking options such as timbre changes, volume adjustments, and replacing the siren unit—based on your vehicle and system.

If you’re concerned, if you can tell us your current configuration, we can organize the scope of changes that are possible and advise you.
