• This explains how things work on set-ups that include a siren. Systems without one, such as an immobiliser on its own, do not sound an alarm.

In principle, it’s not set up so that the siren keeps sounding continuously once it starts.

With our standard settings, when an abnormality is detected the siren will activate, and then it will stop on its own for the time being. How long it sounds can be adjusted depending on the type of system and its settings, but in every case it will not simply keep sounding, so please rest assured. However, since the vehicle is still under surveillance even after the siren stops, if someone attempts to do something to the vehicle again, the siren will sound again.

For this reason, many people worry that the siren might keep blaring endlessly to the point of disturbing the neighbors, but you don’t need to worry about it excessively.
The actual operating time may vary depending on the vehicle model, the installation details, and the settings. If you’re concerned, feel free to contact us and we’ll guide you in an easy-to-understand way.
Please note that the siren sounding when a door is opened while the system is armed is normal behaviour, not a fault.
If the siren goes off repeatedly over a short period, it may be picking up something it should not — please get in touch and we can look at the sensitivity and the settings.
